So, I'm familiar with Javascript, HTML, and Python. I have never learned PHP, and at the moment, I'm banging my head against my desk trying to figure out what (to me) seems to be such a simple thing.
I have a folder, with other folders, that contain images.
At the moment, I'm literally just trying to get a list of the folders as links. I get kind of there, but then my output is always reversed! Folder01, Folder02 comes out as Folder02, Folder01. I can't fricken' sort my output. I've been searching constantly trying to figure this out but nothing is working for me.
<?php
function listAlbums(){
if ($handle = opendir('./photos/')) {
while (false !== ($entry = readdir($handle))) {
if ($entry != "." && $entry != "..") {
echo $entry . "<br/>";
}
}
closedir($handle);
}
}
?>
This outputs: Folder02, Folder01. I need it the other way around. I've tried asort, array_reverse, etc. but I must not be using them properly. This is killing me. I never had to even thin about this in Python, or Javascript, unless I actually wanted to have an ascending list...
Try one of these, one is recursive, one is not:
// Recursive
function listAlbums($path = './photos/')
{
$objects = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path));
foreach($objects as $name => $object) {
ob_start();
echo rtrim($object,".");
$data = ob_get_contents();
ob_end_clean();
$arr[] = $data;
}
return array_unique($arr);
}
// Non-recursive
function getAlbums($path = './photos/')
{
$objects = dir($path);
while (false !== ($entry = $objects->read())) {
if($entry !== '.' && $entry !== '..')
$arr[] = $path.$entry;
}
$objects->close();
return $arr;
}
// I would use __DIR__, but not necessary
$arr = listAlbums();
$arr2 = getAlbums();
// Reverse arrays by key
krsort($arr);
krsort($arr2);
// Show arrays
print_r($arr);
print_r($arr2);
I try your code and make simple changes and I am able to do what you want to get.
Here is my code ( copy of your code + Modify ) :
function listAlbums() {
$files = array();
if ($handle = opendir('./photos/')) {
while (false !== ($entry = readdir($handle))) {
if ($entry != "." && $entry != "..") {
//echo $entry . "<br/>";
$files[] = $entry;
}
}
closedir($handle);
}
// Sort your folder in ascending order
sort($files);
// Sort your folder in descending order [ code commented ]
//rsort($files);
// Check your photos folder has folder or not
if( !empty( $files ) ) {
// Show Your Folders
foreach ($files as $key => $folderName ) {
echo $folderName . "<br/>";
}
} else {
echo 'You have no folder yet in photos directory';
}
}
My Changes:
First store your all folders in the photos directory in an array variable
Secondly sort this array whatever order you want.
Finally show your folders (And your work will be solved)
You can know more about this from sort-and-display-directory-list-alphabetically-using-opendir-in-php
Thanks
Ok, this is the best result i've gotten all night. This does 99% of what I need. But I still can't figure out this damn sort issue. This code will go through a list of directories, and create lightbox galleries out of the images in each folder. However, the first image is always the last one in the array, and I can't figure out how the heck to get it to sort normally! Check line 16 to see where I talking about.
<?php
function listAlbums(){
$directory = "./photos/";
//get all folders in specified directory
$folders = glob($directory . "*");
//get each folder item name
foreach($folders as $folderItem){
//check to see if the folderItem is a folder/directory
if(is_dir($folderItem)){
$count = 0;
foreach (new DirectoryIterator($folderItem) as $fileInfo) {
if($fileInfo->isDot()) continue;
$files = $folderItem."/".$fileInfo->getFilename();
if ($count == 0){ //This is where my issues start. This file ends up being the last one in the list. I need it to be the first.
echo ''.basename($folderItem).'' . "<br/>";
echo "<div style='display: none'>" . "<br/>";
$count++;
}else{
echo ''.basename($folderItem).'' . "<br/>";
}
}echo "</div>";
}
}
}
?>
Whew! Ok, I got everything working. DirectoryIterator was pissing me off with its random print order. So I fell back to just glob and scandir. Those seem to print out a list "logically". To summarize, this bit of php will grab folders of images and turn each folder into its own lightbox gallery. Each gallery shows up as a hyperlink that triggers the lightbox gallery. I'm pretty happy with it!
So here's my final code:
<?php
function listAlbums(){
$directory = "./photos/";
//get all folders in specified directory
$folders = glob($directory . "*");
//get each folder item name
foreach($folders as $folderItem){
//check to see if the folderItem is a folder/directory
if(is_dir($folderItem)){
$count = 0;
$scanDir = scandir($folderItem);
foreach($scanDir as $file){
if ($file === '.' || $file === '..') continue;
$filePath = $folderItem."/".$file;
if ($count == 0){
echo ''.basename($folderItem).'' . "<br/>";
echo "<div style='display: none'>" . "<br/>";
$count++;
}else{
echo ''.basename($folderItem).'' . "<br/>";
}
}echo "</div>";
}
}
}
Special thanks to Rasclatt for bearing with me through all of this and offering up a lot of hand-holding and help. I really appreciate it!
Having issues writing a function to return the directories contained within one directory and then placing all of each directories file paths into an array called $files.
I've got the Directory collection working, but can't seem to create the file array
Here's the code I have so far:
<?php
function find_recursive_images_and_dirs($path, $option) {
try {
$iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path),
RecursiveIteratorIterator::CHILD_FIRST);
foreach ($iterator as $path) {
if ($path->isDir()) {
if(substr($path->__toString(), (strrpos($path->__toString(), "/")+1)) != "." && substr($path->__toString(), (strrpos($path->__toString(), "/")+1)) != ".."){
$directories[] = $path->__toString();
$childrenIterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator(($path->__toString() . "/")), RecursiveIteratorIterator::CHILD_FIRST);
//echo $path->getChildren() . "</br>";
echo "<pre>" . var_dump($path) . "</pre>";
foreach ($childrenIterator as $child) {
echo "Entered!2";
if(substr($path->__toString(), (strrpos($path->__toString(), "/")+1)) != "." && substr($path->__toString(), (strrpos($path->__toString(), "/")+1)) != ".."){
echo "Entered!3";
echo $child->__toString();
$files[] = $child->__toString();
}
}
}
} /*else {
$files[] = $path->__toString();
}*/
}
if($option == "files")
return $files;
else if($option == "directories")
return $directories;
} catch (Exception $e) {
echo "/* There was a problem, error: " . $e . " */";
}
}
$path = "../administrator/panel/gallery/public/";
$files = find_recursive_images_and_dirs($path, "files");
$directories = find_recursive_images_and_dirs($path, "directories");
print_r($files);
?>
I tried the getChildren() method, but it just spits out an error, so I ended up trying to create a new recursive directory iterator using the dir path returned when checking whether the file is a directory in the main folder. The program then uses that path and does the same thing, only this time it places the files listed in each folder in an array named $files, but for some reason, nothing is being stored in the array, in fact, it doesn't even enter the second foreach().
I'm trying to create a dynamic image gallery script, so that a client, once I'm done with the site, can upload images via FTP and the site will update automatically. I'm using a script I found on here, but I cannot get it to work for the life of me. The PHP writes information, but will never actually write out the images it's supposed to find in the directory. Not sure why. Demo here and you can see the working code (without PHP) here.
<?php
function getDirTree($dir,$p=true) {
$d = dir($dir);$x=array();
while (false !== ($r = $d->read())) {
if($r!="."&&$r!=".."&&(($p==false&&is_dir($dir.$r))||$p==true)) {
$x[$r] = (is_dir($dir.$r)?array():(is_file($dir.$r)?true:false));
}
}
foreach ($x as $key => $value) {
if (is_dir($dir.$key."/")) {
$x[$key] = getDirTree($dir.$key."/",$p);
}
}
ksort($x);
return $x;
}
$path = "../images/bettydew/";
$tree = getDirTree($path);
echo '<ul class="gallery">';
foreach($tree as $element => $eval) {
if (is_array($eval)) {
foreach($eval as $file => $value) {
if (strstr($file, "png")||strstr($file, "jpg")||strstr($file, "bmp")||strstr($file, "gif")) {
$item = $path.$file;
echo '<img src="'.$item.'" alt="'.$item.'"/>';
}
}
}
}
echo '</ul>';
?>
path problem and a recursion problem in the sub-directories.
perhaps try this:
<?php
$path = "./images/bettydew/";
$file_array = array ();
readThisDir ( $path, &$file_array );
echo '<ul class="gallery">';
foreach ( $file_array as $file )
{
if (strstr($file, "png")||strstr($file, "jpg")||strstr($file, "bmp")||strstr($file, "gif"))
{
list($width, $height) = getimagesize($file);
echo '<li><img src="'.$file.'" width="'.$width.'" height="'.$height.'" alt="'.$file.'"/></li>';
}
}
echo '</ul>';
function readThisDir ( $path, $arr )
{
if ($handle = opendir($path))
{
while (false !== ($file = readdir($handle)))
{
if ($file != "." && $file != "..")
{
if (is_dir ( $path."/".$file ))
{
readThisDir ($path."/".$file, &$arr);
} else {
$arr[] = $path."/".$file;
}
}
}
closedir($handle);
}
}
?>
Either Your path is mistake... it caused me similar error when i feed wrong path to the $path variable.
Or you do not have read permission on that directory... check the permissions too
And remember to check '/' at the end of your path as without it your code cannot do recursive search inside the child directory...
And finally your code will not give the correct file path of the files of sub-directory while writing output... so check it too...
I wonder, what's the easiest way to delete a directory with all its files in it?
I'm using rmdir(PATH . '/' . $value); to delete a folder, however, if there are files inside of it, I simply can't delete it.
There are at least two options available nowadays.
Before deleting the folder, delete all its files and folders (and this means recursion!). Here is an example:
public static function deleteDir($dirPath) {
if (! is_dir($dirPath)) {
throw new InvalidArgumentException("$dirPath must be a directory");
}
if (substr($dirPath, strlen($dirPath) - 1, 1) != '/') {
$dirPath .= '/';
}
$files = glob($dirPath . '*', GLOB_MARK);
foreach ($files as $file) {
if (is_dir($file)) {
self::deleteDir($file);
} else {
unlink($file);
}
}
rmdir($dirPath);
}
And if you are using 5.2+ you can use a RecursiveIterator to do it without implementing the recursion yourself:
$dir = 'samples' . DIRECTORY_SEPARATOR . 'sampledirtree';
$it = new RecursiveDirectoryIterator($dir, RecursiveDirectoryIterator::SKIP_DOTS);
$files = new RecursiveIteratorIterator($it,
RecursiveIteratorIterator::CHILD_FIRST);
foreach($files as $file) {
if ($file->isDir()){
rmdir($file->getRealPath());
} else {
unlink($file->getRealPath());
}
}
rmdir($dir);
I generally use this to delete all files in a folder:
array_map('unlink', glob("$dirname/*.*"));
And then you can do
rmdir($dirname);
what's the easiest way to delete a directory with all its files in it?
system("rm -rf ".escapeshellarg($dir));
Short function that does the job:
function deleteDir($path) {
return is_file($path) ?
#unlink($path) :
array_map(__FUNCTION__, glob($path.'/*')) == #rmdir($path);
}
I use it in a Utils class like this:
class Utils {
public static function deleteDir($path) {
$class_func = array(__CLASS__, __FUNCTION__);
return is_file($path) ?
#unlink($path) :
array_map($class_func, glob($path.'/*')) == #rmdir($path);
}
}
With great power comes great responsibility: When you call this function with an empty value, it will delete files starting in root (/). As a safeguard you can check if path is empty:
function deleteDir($path) {
if (empty($path)) {
return false;
}
return is_file($path) ?
#unlink($path) :
array_map(__FUNCTION__, glob($path.'/*')) == #rmdir($path);
}
As seen in most voted comment on PHP manual page about rmdir() (see http://php.net/manual/es/function.rmdir.php), glob() function does not return hidden files. scandir() is provided as an alternative that solves that issue.
Algorithm described there (which worked like a charm in my case) is:
<?php
function delTree($dir)
{
$files = array_diff(scandir($dir), array('.', '..'));
foreach ($files as $file) {
(is_dir("$dir/$file")) ? delTree("$dir/$file") : unlink("$dir/$file");
}
return rmdir($dir);
}
?>
You may use Symfony's Filesystem (code):
// composer require symfony/filesystem
use Symfony\Component\Filesystem\Filesystem;
(new Filesystem)->remove($dir);
However I couldn't delete some complex directory structures with this method, so first you should try it to ensure it's working properly.
I could delete the said directory structure using a Windows specific implementation:
$dir = strtr($dir, '/', '\\');
// quotes are important, otherwise one could
// delete "foo" instead of "foo bar"
system('RMDIR /S /Q "'.$dir.'"');
And just for the sake of completeness, here is an old code of mine:
function xrmdir($dir) {
$items = scandir($dir);
foreach ($items as $item) {
if ($item === '.' || $item === '..') {
continue;
}
$path = $dir.'/'.$item;
if (is_dir($path)) {
xrmdir($path);
} else {
unlink($path);
}
}
rmdir($dir);
}
This is a shorter Version works great to me
function deleteDirectory($dirPath) {
if (is_dir($dirPath)) {
$objects = scandir($dirPath);
foreach ($objects as $object) {
if ($object != "." && $object !="..") {
if (filetype($dirPath . DIRECTORY_SEPARATOR . $object) == "dir") {
deleteDirectory($dirPath . DIRECTORY_SEPARATOR . $object);
} else {
unlink($dirPath . DIRECTORY_SEPARATOR . $object);
}
}
}
reset($objects);
rmdir($dirPath);
}
}
You can try as follows:
/*
* Remove the directory and its content (all files and subdirectories).
* #param string $dir the directory name
*/
function rmrf($dir) {
foreach (glob($dir) as $file) {
if (is_dir($file)) {
rmrf("$file/*");
rmdir($file);
} else {
unlink($file);
}
}
}
I can't believe there are 30+ answers for this. Recursively deleting a folder in PHP could take minutes depending on the depth of the directory and the number of files in it! You can do this with one line of code ...
shell_exec("rm -rf " . $dir);
If you're concerned with deleting the entire filesystem, make sure your $dir path is exactly what you want first. NEVER allow a user to input something that can directly delete files without first heavily validating the input. That's essential coding practice.
This one works for me:
function removeDirectory($path) {
$files = glob($path . '/*');
foreach ($files as $file) {
is_dir($file) ? removeDirectory($file) : unlink($file);
}
rmdir($path);
return;
}
Here you have one nice and simple recursion for deleting all files in source directory including that directory:
function delete_dir($src) {
$dir = opendir($src);
while(false !== ( $file = readdir($dir)) ) {
if (( $file != '.' ) && ( $file != '..' )) {
if ( is_dir($src . '/' . $file) ) {
delete_dir($src . '/' . $file);
}
else {
unlink($src . '/' . $file);
}
}
}
closedir($dir);
rmdir($src);
}
Function is based on recursion made for copying directory. You can find that function here:
Copy entire contents of a directory to another using php
Glob function doesn't return the hidden files, therefore scandir can be more useful, when trying to delete recursively a tree.
<?php
public static function delTree($dir) {
$files = array_diff(scandir($dir), array('.','..'));
foreach ($files as $file) {
(is_dir("$dir/$file")) ? delTree("$dir/$file") : unlink("$dir/$file");
}
return rmdir($dir);
}
?>
Example for the Linux server: exec('rm -f -r ' . $cache_folder . '/*');
Litle bit modify of alcuadrado's code - glob don't see files with name from points like .htaccess so I use scandir and script deletes itself - check __FILE__.
function deleteDir($dirPath) {
if (!is_dir($dirPath)) {
throw new InvalidArgumentException("$dirPath must be a directory");
}
if (substr($dirPath, strlen($dirPath) - 1, 1) != '/') {
$dirPath .= '/';
}
$files = scandir($dirPath);
foreach ($files as $file) {
if ($file === '.' || $file === '..') continue;
if (is_dir($dirPath.$file)) {
deleteDir($dirPath.$file);
} else {
if ($dirPath.$file !== __FILE__) {
unlink($dirPath.$file);
}
}
}
rmdir($dirPath);
}
The Best Solution for me
my_folder_delete("../path/folder");
code:
function my_folder_delete($path) {
if(!empty($path) && is_dir($path) ){
$dir = new RecursiveDirectoryIterator($path, RecursiveDirectoryIterator::SKIP_DOTS); //upper dirs are not included,otherwise DISASTER HAPPENS :)
$files = new RecursiveIteratorIterator($dir, RecursiveIteratorIterator::CHILD_FIRST);
foreach ($files as $f) {if (is_file($f)) {unlink($f);} else {$empty_dirs[] = $f;} } if (!empty($empty_dirs)) {foreach ($empty_dirs as $eachDir) {rmdir($eachDir);}} rmdir($path);
}
}
p.s. REMEMBER! dont pass EMPTY VALUES to any Directory deleting functions!!! (backup them always, otherwise one day you might get DISASTER!!)
I want to expand on the answer by #alcuadrado with the comment by #Vijit for handling symlinks. Firstly, use getRealPath(). But then, if you have any symlinks that are folders it will fail as it will try and call rmdir on a link - so you need an extra check.
$it = new RecursiveDirectoryIterator($dir, RecursiveDirectoryIterator::SKIP_DOTS);
$files = new RecursiveIteratorIterator($it, RecursiveIteratorIterator::CHILD_FIRST);
foreach($files as $file) {
if ($file->isLink()) {
unlink($file->getPathname());
} else if ($file->isDir()){
rmdir($file->getPathname());
} else {
unlink($file->getPathname());
}
}
rmdir($dir);
I prefer this because it still returns TRUE when it succeeds and FALSE when it fails, and it also prevents a bug where an empty path might try and delete everything from '/*' !!:
function deleteDir($path)
{
return !empty($path) && is_file($path) ?
#unlink($path) :
(array_reduce(glob($path.'/*'), function ($r, $i) { return $r && deleteDir($i); }, TRUE)) && #rmdir($path);
}
What about this:
function recursiveDelete($dirPath, $deleteParent = true){
foreach(new RecursiveIteratorIterator(new RecursiveDirectoryIterator($dirPath, FilesystemIterator::SKIP_DOTS), RecursiveIteratorIterator::CHILD_FIRST) as $path) {
$path->isFile() ? unlink($path->getPathname()) : rmdir($path->getPathname());
}
if($deleteParent) rmdir($dirPath);
}
Using DirectoryIterator an equivalent of a previous answer…
function deleteFolder($rootPath)
{
foreach(new DirectoryIterator($rootPath) as $fileToDelete)
{
if($fileToDelete->isDot()) continue;
if ($fileToDelete->isFile())
unlink($fileToDelete->getPathName());
if ($fileToDelete->isDir())
deleteFolder($fileToDelete->getPathName());
}
rmdir($rootPath);
}
you can try this simple 12 line of code for delete folder or folder files...
happy coding... ;) :)
function deleteAll($str) {
if (is_file($str)) {
return unlink($str);
}
elseif (is_dir($str)) {
$scan = glob(rtrim($str,'/').'/*');
foreach($scan as $index=>$path) {
$this->deleteAll($path);
}
return #rmdir($str);
}
}
Something like this?
function delete_folder($folder) {
$glob = glob($folder);
foreach ($glob as $g) {
if (!is_dir($g)) {
unlink($g);
} else {
delete_folder("$g/*");
rmdir($g);
}
}
}
Delete all files in Folder
array_map('unlink', glob("$directory/*.*"));
Delete all .*-Files in Folder (without: "." and "..")
array_map('unlink', array_diff(glob("$directory/.*),array("$directory/.","$directory/..")))
Now delete the Folder itself
rmdir($directory)
2 cents to add to THIS answer above, which is great BTW
After your glob (or similar) function has scanned/read the directory, add a conditional to check the response is not empty, or an invalid argument supplied for foreach() warning will be thrown. So...
if( ! empty( $files ) )
{
foreach( $files as $file )
{
// do your stuff here...
}
}
My full function (as an object method):
private function recursiveRemoveDirectory( $directory )
{
if( ! is_dir( $directory ) )
{
throw new InvalidArgumentException( "$directory must be a directory" );
}
if( substr( $directory, strlen( $directory ) - 1, 1 ) != '/' )
{
$directory .= '/';
}
$files = glob( $directory . "*" );
if( ! empty( $files ) )
{
foreach( $files as $file )
{
if( is_dir( $file ) )
{
$this->recursiveRemoveDirectory( $file );
}
else
{
unlink( $file );
}
}
}
rmdir( $directory );
} // END recursiveRemoveDirectory()
Here is the solution that works perfect:
function unlink_r($from) {
if (!file_exists($from)) {return false;}
$dir = opendir($from);
while (false !== ($file = readdir($dir))) {
if ($file == '.' OR $file == '..') {continue;}
if (is_dir($from . DIRECTORY_SEPARATOR . $file)) {
unlink_r($from . DIRECTORY_SEPARATOR . $file);
}
else {
unlink($from . DIRECTORY_SEPARATOR . $file);
}
}
rmdir($from);
closedir($dir);
return true;
}
What about this?
function Delete_Directory($Dir)
{
if(is_dir($Dir))
{
$files = glob( $Dir . '*', GLOB_MARK ); //GLOB_MARK adds a slash to directories returned
foreach( $files as $file )
{
Delete_Directory( $file );
}
if(file_exists($Dir))
{
rmdir($Dir);
}
}
elseif(is_file($Dir))
{
unlink( $Dir );
}
}

You could copy the YII helpers
$directory (string) - to be deleted recursively.
$options (array) - for the directory removal.
Valid options are:
traverseSymlinks: boolean, whether symlinks to the directories should be traversed too. Defaults to false, meaning that the content of the symlinked directory would not be deleted. Only symlink would be removed in that default case.
public static function removeDirectory($directory,$options=array())
{
if(!isset($options['traverseSymlinks']))

Have your tryed out the obove code from php.net
Work for me fine
For windows:
system("rmdir ".escapeshellarg($path) . " /s /q");
Like Playnox's solution, but with the elegant built-in DirectoryIterator:
function delete_directory($dirPath){
if(is_dir($dirPath)){
$objects=new DirectoryIterator($dirPath);
foreach ($objects as $object){
if(!$object->isDot()){
if($object->isDir()){
delete_directory($object->getPathname());
}else{
unlink($object->getPathname());
}
}
}
rmdir($dirPath);
}else{
throw new Exception(__FUNCTION__.'(dirPath): dirPath is not a directory!');
}
}
I do not remember from where I copied this function, but it looks like it is not listed and it is working for me
function rm_rf($path) {
if (#is_dir($path) && is_writable($path)) {
$dp = opendir($path);
while ($ent = readdir($dp)) {
if ($ent == '.' || $ent == '..') {
continue;
}
$file = $path . DIRECTORY_SEPARATOR . $ent;
if (#is_dir($file)) {
rm_rf($file);
} elseif (is_writable($file)) {
unlink($file);
} else {
echo $file . "is not writable and cannot be removed. Please fix the permission or select a new path.\n";
}
}
closedir($dp);
return rmdir($path);
} else {
return #unlink($path);
}
}

[0] => /var/www/html/copy2/Copy (5) of New Text Document.txt
[1] => /var/www/html/copy2/Copy of New Text Document.txt
)
Mirror Array
(
[0] => /var/www/html/copy1/Copy (2) of New Text Document.txt
[1] => /var/www/html/copy1/Copy (3) of New Text Document.txt
[2] => /var/www/html/copy1/Copy (5) of New Text Document.txt
)
Difference Array
(
[0] => /var/www/html/copy1/Copy (2) of New Text Document.txt
[1] => /var/www/html/copy1/Copy (3) of New Text Document.txt
[2] => /var/www/html/copy1/Copy (5) of New Text Document.txt

when i iterate a loop to delete on difference array all files has to be deleted as per displayed output.. how can i rectify this.. the loop for deletion is given below.
$dirs_to_delete = array();
foreach ($diff_path as $path) {
if (is_dir($path)) {
$dirs_to_delete[] = $path;
} else {
unlink($path);
}
}
while ($dir = array_pop($dirs_to_delete)) {
rmdir($dir);
}
First you need a recursive listing of both directories. A simple function like this will work:
function scan_dir_recursive($dir, $rel = null) {
$all_paths = array();
$new_paths = scandir($dir);
foreach ($new_paths as $path) {
if ($path == '.' || $path == '..') {
continue;
}
if ($rel === null) {
$path_with_rel = $path;
} else {
$path_with_rel = $rel . DIRECTORY_SEPARATOR . $path;
}
$full_path = $dir . DIRECTORY_SEPARATOR . $path;
$all_paths[] = $path_with_rel;
if (is_dir($full_path)) {
$all_paths = array_merge(
$all_paths, scan_dir_recursive($full_path, $path_with_rel)
);
}
}
return $all_paths;
}
Then you can compute their difference with array_diff.
$diff_paths = array_diff(
scan_dir_recursive('/foo/bar/mirror'),
scan_dir_recursive('/qux/baz/source')
);
Iterating over this array, you will be able to start deleting files. Directories are a bit trickier because they must be empty first.
// warning: test this code yourself before using on real data!
$dirs_to_delete = array();
foreach ($diff_paths as $path) {
if (is_dir($path)) {
$dirs_to_delete[] = $path;
} else {
unlink($path);
}
}
while ($dir = array_pop($dirs_to_delete)) {
rmdir($dir);
}
I've tested things and it should be working well now. Of course, don't take my word for it. Make sure to setup your own safe test before deleting real data.
For recursive directories please use:
$modified_directory = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator('path/to/modified'), true
);
$modified_files = array();
foreach ($modified_directory as $file)
{
$modified_files []= $file->getPathname();
}
You can do other things like $file->isDot(), or $file->isFile(). For more file commands with SPLFileInfo visit http://www.php.net/manual/en/class.splfileinfo.php
Thanks all for the precious time given to my work, Special Thanks to erisco for his dedication for my problem, Below Code is the perfect code to acomplish the task I was supposed to do, with a little change in the erisco's last edited reply...
$source = '/var/www/html/copy1';
$mirror = '/var/www/html/copy2';
function scan_dir_recursive($dir, $rel = null) {
$all_paths = array();
$new_paths = scandir($dir);
foreach ($new_paths as $path) {
if ($path == '.' || $path == '..') {
continue;
}
if ($rel === null) {
$path_with_rel = $path;
} else {
$path_with_rel = $rel . DIRECTORY_SEPARATOR . $path;
}
$full_path = $dir . DIRECTORY_SEPARATOR . $path;
$all_paths[] = $path_with_rel;
if (is_dir($full_path)) {
$all_paths = array_merge(
$all_paths, scan_dir_recursive($full_path, $path_with_rel)
);
}
}
return $all_paths;
}
$diff_paths = array_diff(
scan_dir_recursive($mirror),
scan_dir_recursive($source)
);
echo "<pre>Difference ";print_r($diff_paths);
$dirs_to_delete = array();
foreach ($diff_paths as $path) {
$path = $mirror."/".$path;//added code to unlink.
if (is_dir($path)) {
$dirs_to_delete[] = $path;
} else {
if(unlink($path))
{
echo "File ".$path. "Deleted.";
}
}
}
while ($dir = array_pop($dirs_to_delete)) {
rmdir($dir);
}
First do a scandir() of the original folder, then do a scandir on mirror folder. start traversing the mirror folder array and check if that file is present in the scandir() of original folder. something like this
$original = scandir('path/to/original/folder');
$mirror = scandir('path/to/mirror/folder');
foreach($mirror as $mirr)
{
if($mirr != '.' && $mirr != '..')
{
if(in_array($mirr, $original))
{
// do not delete the file
}
else
{
// delete the file
unlink($mirr);
}
}
}
this should solve your problem. you will need to modify the above code accordingly (include some recursion in the above code to check if the folder that you are trying to delete is empty or not, if it is not empty then you will first need to delete all the file/folders in it and then delete the parent folder).
