So I'm creating an image upload site and I need to delete multiple directories and files simultaneously. I have managed to create code that does the job however I'm unsure whether this is 'good code' as I'm repeating myself.
Is there a better way to write the below?
$dirname = 'uploads/'.$album_id;
$dirnamethumb = 'uploads/thumbs/'.$album_id;
if (is_dir($dirname))
$dir_handle = opendir($dirname);
if (!$dir_handle)
return false;
while($file = readdir($dir_handle)) {
if ($file != "." && $file != "..") {
if (!is_dir($dirname."/".$file))
unlink($dirname."/".$file);
else
delete_directory($dirname.'/'.$file);
}
}
if (is_dir($dirnamethumb))
$dir_handle = opendir($dirnamethumb);
if (!$dir_handle)
return false;
while($file = readdir($dir_handle)) {
if ($file != "." && $file != "..") {
if (!is_dir($dirnamethumb."/".$file))
unlink($dirnamethumb."/".$file);
else
delete_directory($dirnamethumb.'/'.$file);
}
}
closedir($dir_handle);
rmdir($dirname);
rmdir($dirnamethumb);
return true;
Thank you in advance for your help!
Why not try this recursive function from similar question
function rrmdir($dir) {
foreach(glob($dir . '/*') as $file) {
if(is_dir($file))
rrmdir($file);
else
unlink($file);
} rmdir($dir);
}
try this,
$dir = '/path/to/some/dir/'; // notice: trailing slash!
if ($handle = opendir($dir)) {
while (false !== ($entry = readdir($handle))) {
if (is_dir($dir . $entry) ) {
rmdir($dir . $entry);
}
}
closedir($handle);
}
?>

I am using this code in order to get a list files from directory:
$dir = '/restosnapp_cms/images/';
if ($dp = opendir($_SERVER['DOCUMENT_ROOT'] . $dir)) {
$files = array();
while (($file = readdir($dp)) !== false) {
if (!is_dir($dir . $file)) {
$files[] = $file;
}
}
closedir($dp);
} else {
exit('Directory not opened.');
}
I want to get rid of the values '.' and '..'.
Is it possible to do this? Thank you. :)
Just check for them first:
while ($file = readdir($p)) {
if ($file == '.' || $file == '..') {
continue;
}
// rest of your code
}
DirectoryIterator is much more fun than *dir functions:
$dir = new DirectoryIterator($_SERVER['DOCUMENT_ROOT'] . $dir);
foreach($dir as $file) {
if (!$file->isDir() && !$file->isDot()) {
$files[] = $file->getPathname();
}
}
But the bottomline is regardless of which way you do it, you need to use a conditional.
I have a directory /main with folders and files inside those folders.
I want to keep directory /main but delete everything in it:
$di = new RecursiveDirectoryIterator('/main');
foreach (new RecursiveIteratorIterator($di) as $filename => $file) {
if(!is_dir($filename)){
unlink($filename);
}
};
This is deleting the files inside the folders, leaving /main with a list of empty folders, how do I delete these now?
I know this should be possible to integrate inside the loop, I tried rmdir without success.
Try this code
UPDATED ANSWER:
$dir = '/home/XXXXX/public_html/';
foreach(glob($dir.'*.*') as $v){
echo $v;
// unlink($v);
}
destroy_dir($dir);
function destroy_dir($dir) {
if (!is_dir($dir) || is_link($dir)) return unlink($dir);
foreach (scandir($dir) as $file) {
if ($file == '.' || $file == '..') continue;
if (!destroy_dir($dir . DIRECTORY_SEPARATOR . $file)) {
chmod($dir . DIRECTORY_SEPARATOR . $file, 0777);
if (!destroy_dir($dir . DIRECTORY_SEPARATOR . $file)) return false;
};
}
return rmdir($dir);
}
Here, Code is not tested.
function delete_directory_files($dirname) {
if (is_dir($dirname))
$dir_handle = opendir($dirname);
if (!$dir_handle)
return false;
while($file = readdir($dir_handle)) {
if ($file != "." && $file != "..") {
if (!is_dir($dirname."/".$file))
unlink($dirname."/".$file);
else
delete_directory($dirname.'/'.$file);
}
}
closedir($dir_handle);
return true;
}
rmdir("./uploads/temp/".$user."/");
I have many files in a directory I wish to remove in my PHP script, however these is no way for me to unlink() the file first. Is there a way I co do
unlink(* FROM (dir=)) // don't downvote the long shot
// delete all files from the dir first
// then delete that dir
Reference a directory has to be empty in order to delete it, see php.net/manual/en/function.rmdir.php
You can use the DirectoryIterator and unlink together.
use this
function delete_directory($dirname) {
if (is_dir($dirname))
$dir_handle = opendir($dirname);
if (!$dir_handle)
return false;
while($file = readdir($dir_handle)) {
if ($file != "." && $file != "..") {
if (!is_dir($dirname."/".$file))
unlink($dirname."/".$file);
else
delete_directory($dirname.'/'.$file);
}
}
closedir($dir_handle);
rmdir($dirname);
return true;
}
This code can easily be improved upon, as it's a quick hack, but it takes a directory as an argument and then uses functional recursion to delete all files and folders within, and then finally removes the directory. Nice and quick, too.
There is no other way except to delete all files first using one way or another and then remove directory.
public static function deleteDir($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);
}
Try using glob to loop over the files in the directory to delete
foreach (glob('/path/to/directory/*') as $file){
unlink('/path/to/directory/' . $file);
}
Check this http://lixlpixel.org/recursive_function/php/recursive_directory_delete/
function recursive_remove_directory($directory, $empty=FALSE)
{
if(substr($directory,-1) == '/')
{
$directory = substr($directory,0,-1);
}
if(!file_exists($directory) || !is_dir($directory))
{
return FALSE;
}elseif(is_readable($directory))
{
$handle = opendir($directory);
while (FALSE !== ($item = readdir($handle)))
{
if($item != '.' && $item != '..')
{
$path = $directory.'/'.$item;
if(is_dir($path))
{
recursive_remove_directory($path);
}else{
unlink($path);
}
}
}
closedir($handle);
if($empty == FALSE)
{
if(!rmdir($directory))
{
return FALSE;
}
}
}
return TRUE;
}
You can delete it recursively:
public function delete_folder ($path) {
$handle = opendir($path);
while ($file = readdir($handle)) {
if ($file != '..' && $file != '.') {
if (is_file($path . DS . $file))
unlink($path . DS . $file);
else
delete_folder($path . DS . $file);
}
}
closedir($handle);
rmdir($tmp_path);
}
delete_folder('path/to/folder');
The function below returns an array of XML files from a given directory including all subdirectories. How can I modify this function by passing a second optional parameter which excludes a directory.
E.g:
getDirXmlFiles($config_dir, "example2");
Directory/Files
/file1.xml
/file2.xml
/examples/file3.xml
/examples/file4.xml
/example2/file5.xml
/example2/file5.xml
In the above case the function would return all files except files in the example2 directory.
function getDirXmlFiles($base) {
$files = array();
if(!is_dir($base)) return $files;
if ($handle = opendir($base)) {
while (false !== ($file = readdir($handle))) {
if ($file == "." || $file == "..") continue;
if(is_dir("$base/$file")) {
$subfiles = $this->getDirXmlFiles("$base/$file");
$files = array_merge($files, $subfiles);
} else {
if(Cms_File::type($file,false) == "xml")
$files[] = "$base/$file";
}
}
closedir($handle);
}
return $files;
}
Try this:
function getDirXmlFiles($base, $exclude = NULL) {
$files = array();
if(!is_dir($base)) return $files;
if ($handle = opendir($base)) {
while (false !== ($file = readdir($handle))) {
if ($file == "." || $file == ".." || "$base/$file" == $exclude) continue;
if(is_dir("$base/$file")) {
$subfiles = $this->getDirXmlFiles("$base/$file",$exclude);
$files = array_merge($files, $subfiles);
} else {
if(Cms_File::type($file,false) == "xml")
$files[] = "$base/$file";
}
}
closedir($handle);
}
return $files;
}
Redefine the function inputs:
function getDirXmlFiles($base, $excludeDir) {
Then change this line:
if(is_dir("$base/$file")) {
to this:
if(is_dir("$base/$file") && "$base/$file" != "$base/$excludeDir") {
You can just slightly modify the function to check and see if the current directory is the one you want to exclude or not
function getDirXmlFiles($base,$exclude) {
$files = array();
if(!is_dir($base)) return $files;
if ($handle = opendir($base)) {
while (false !== ($file = readdir($handle))) {
if ($file == "." || $file == "..") continue;
if(is_dir("$base/$file") && $file != $exclude) {
$subfiles = $this->getDirXmlFiles("$base/$file",$exclude);
$files = array_merge($files, $subfiles);
} else {
if(Cms_File::type($file,false) == "xml")
$files[] = "$base/$file";
}
}
closedir($handle);
}
return $files;
}
Smth of the sort ( tested only the syntax validation there might be needed some small debugging ) ( this will allow you to exclude multiple directory names )
function getDirXmlFiles($base, $excludeArray = array()) {
if (!is_array($excludeArray))
throw new Exception(__CLASS__ . "->" . __METHOD__ . " expects second argument to be a valid array");
$files = array();
if(!is_dir($base)) return $files;
if ($handle = opendir($base)) {
while (false !== ($file = readdir($handle))) {
$path = $base . "/" . $file;
$isDir = is_dir($path);
if (
$file == "."
|| $file == ".."
|| (
$isDir
&& count($excludeArray) > 0
&& in_array($file, $excludeArray)
)
)
continue;
if($isDir) {
$subfiles = $this->getDirXmlFiles($path, $excludeArray);
$files = array_merge($files, $subfiles);
} else {
if(Cms_File::type($file,false) == "xml")
$files[] = $path;
}
}
closedir($handle);
}
return $files;
}
how can i delete multiple files from the folder?
code:$query=$this->main_model->get($id);
if($query->num_rows()>0)
{
foreach ($query->result() as $row)
{
unlink("uploads/".$id."/".$row->img_name);
unlink("uploads/".$id."/".$row->img_name_tn);
unlink("uploads/".$id."/".$row->file);
unlink("uploads/".$id."/".$row->file2);
unlink("uploads/".$id."/Thumbs.db");
}
rmdir("uploads/".$id);
}
here is the code i used but it delete the files at ones. and how can i delete all files from the folder?
originally from php.net:
<?php
$dir = '/uploads/';
if ($handle = opendir($dir)) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") { // strip the current and previous directory items
unlink($dir . $file); // you can add some filters here, aswell, to filter datatypes, file, prefixes, suffixes, etc
}
}
closedir($handle);
}
?>
I found this at php.net:
"The shortest recursive delete possible"
function rrmdir($path) {
return is_file($path)?
#unlink($path):
array_map('rrmdir',glob($path.'/*'))==#rmdir($path)
;
}
You could do it like this:
function delete_files($dirname) {
if (is_dir($dirname))
$dir_handle = opendir($dirname);
if (!$dir_handle)
return false;
while($file = readdir($dir_handle)) {
if ($file != "." && $file != "..") {
if (!is_dir($dirname."/".$file))
unlink($dirname."/".$file);
}
}
closedir($dir_handle);
return true;
}
You need to use a recursive function. A comment from the rmdir page have written a function on how to do it, see http://www.php.net/manual/en/function.rmdir.php#98622. This code will delete the folder and everything in it.
<?php
function rrmdir($dir) {
if (is_dir($dir)) {
$objects = scandir($dir);
foreach ($objects as $object) {
if ($object != "." && $object != "..") {
if (filetype($dir."/".$object) == "dir") rrmdir($dir."/".$object); else unlink($dir."/".$object);
}
}
reset($objects);
rmdir($dir);
}
}
?>
