List all .jpg files from all folders and subfolders - php

I would like to list all .jpg files from folders and subfolders.
I have that simple code:
<?php
// directory
$directory = "img/*/";
// file type
$images = glob("" . $directory . "*.jpg");
foreach ($images as $image) {
echo $image."<br>";
}
?>
But that lists .jpg files from img folder and one down.
How to scan all subfolders?

Php coming with the DirectoryIterator which can be very useful in that case.
Please note that this simple function can be easly improved by adding the whole path to a file instead the only file name, and maybe use something else instead of the reference.
/*
* Find all file of the given type.
* #dir : A directory from which to start the search
* #ext : The extension. XXX : Dont call it with "." separator
* #store : A REFERENCE to an array on which store the element found.
* */
function allFileOfType($dir, $ext, &$store) {
foreach(new DirectoryIterator($dir) as $subItem) {
if ($subItem->isFile() && $subItem->getExtension() == $ext)
array_push($store, $subItem->getFileName());
elseif(!$subItem->isDot() && $subItem->isDir())
allFileOfType($subItem->getPathName(), $ext, $store);
}
}
$jpgStore = array();
allFileOfType(__DIR__, "jpg", $jpgStore);
print_r($jpgStore);

As a directotry can contain subdirectories, and in their turn contains subdirectories, so we should use a recursive function. glob() is here not sufficient. This might work for you:
<?php
function getDir4JpgR($directory) {
if ($handle = opendir($directory)) {
while (false !== ($entry = readdir($handle))) {
if($entry != "." && $entry != "..") {
$str1 = "$directory/$entry";
if(preg_match("/\.jpg$/i", $entry)) {
echo $str1 . "<br />\n";
} else {
if(is_dir($str1)) {
getDir4JpgR($str1);
}
}
}
}
closedir($handle);
}
}
//
// call the recursive function in the main block:
//
// directory
$directory = "img";
getDir4JpgR($directory);
?>
I put this into a file named listjpgr.php. And in my Chrome Browser, it gives this capture:

How to echo out the contents of every text file that in a directory?

I have created a directory with some files in there:
index.php
one.txt
two.txt
three.txt
four.txt
In the index.php page, I am currently using this code to echo out all of the files within the directory:
<?php
$blacklist = array("index.php");
if ($handle = opendir('.')) {
while (false !== ($entry = readdir($handle))) {
if ($entry != "." && $entry != ".." && !in_array($entry, $blacklist)) {
echo "$entry\n";
}
}
closedir($handle);
}
?>
Now, if anyone views the index.php page, this is what they'll see:
one.txt two.txt three.txt four.txt
As you can see from the PHP code, index.php is blacklisted so it is not echoed out.
However, I would like to go a step further than this and echo out the contents of each text file rather than the filenames. With the new PHP code (that I need help with creating), whenever someone visits the index.php page, this is what they'll now see:
(Please ignore what is in the asterisks, they are not a part of the code, they just indicate what each text file contains)
Hello ** this is what the file **one.txt** contains **
ok ** this is what the file **two.txt** contains **
goodbye ** this is what the file **three.txt** contains **
text ** this is what the file **four.txt** contains **
Overall:
I would like to echo out the contents of every file in the directory (they are all text files) aside from index.php.
You could use file_get_contents to put the file into a string.
<?php
$blacklist = array("index.php");
if ($handle = opendir('.')) {
while (false !== ($entry = readdir($handle))) {
if ($entry != "." && $entry != ".." && !in_array($entry, $blacklist)) {
echo "$entry " . file_get_contents($entry) . "\n";
}
}
closedir($handle);
}
?>
Furthermore, you could use PHP's glob function to filter only the .txt files out, that way you do not have to blacklist files if you're going to be adding more files to that directory that need ignored.
Here is how it would be done using the glob function.
<?php
foreach (glob("*.txt") as $filename) {
echo "$filename " . file_get_contents($filename) . "\n";
}
?>
This would print the contents of the files. You can do some workaround if the path is not the current path and writing some kind of boundary between the files contents.
<?php
$blacklist = array("index.php");
if ($handle = opendir('.')) {
while (false !== ($entry = readdir($handle))) {
if ($entry != "." && $entry != ".." && !in_array($entry, $blacklist)) {
echo file_get_contents($entry) . "\n";
}
}
closedir($handle);
}
?>
I hope this helps you.
Never reinvent the wheel. Use composer.
Require symfony/finder
use Symfony\Component\Finder\Finder;
class Foo
{
public function getTextFileContents($dir)
{
$finder = (new Finder())->files()->name('*.txt');
foreach ($finder->in($dir) as $file) {
$contents = $file->getContents();
// do something while file contents...
}
}
}
I would give a chance to some SPL filesystem iterators to accomplish such this task:
$dir = '/home/mydirectory';
$rdi = new \RecursiveDirectoryIterator($dir, \FilesystemIterator::SKIP_DOTS);
$rdi = new \RegexIterator($rdi, '/\.txt$/i');
$iterator = new \RecursiveIteratorIterator($rdi, \RecursiveIteratorIterator::CHILD_FIRST);
foreach ($iterator as $file) {
echo 'Contents of the '.$file->getPathname().' is: ';
echo file_get_contents($file->getPathname());
}
This will recursively find & iterate all .txt files in given directory, including sub-directories.
Since each $file in iteration is a FilesystemIterator instance, you can use all related methods for additional controls like $file->isLink() (true for symbolic links), $file->isReadable() (false for unreadable files) etc..
If you don't want lookup sub-folders, just change the RecursiveDirectoryIterator in the second line from:
$rdi = new \RecursiveDirectoryIterator($dir, \FilesystemIterator::SKIP_DOTS);
to:
$rdi = new \DirectoryIterator($dir, \FilesystemIterator::SKIP_DOTS);
Hope it helps.
As #brock-b said, you could use glob to get the full list of files and file_get_contents to grab the contents:
$blacklist = array('index.php');
$files = glob('*.txt'); # could be *.* if needed
foreach ($files as $file) {
if (!in_array(basename($file), $blacklist)) {
echo file_get_contents($file);
}
}
Note: the blacklist wont be hit since you're seeking for *.txt files. Only useful when doing an *.* or *.php file search

Php Show Files after listing directory (Part 2)

This is a part two to my previous question that got answered Php Browsing Multiple Directories
Now that I got the script reading the directories perfectly, Is it possible to load the results of the file listings into a new page like races.php to "pretty it up"
Here is how it's listing the files Example of Files being listed from server
I would really like to have that be displayed inside of the site instead of jumping out into a apache server listing so its more user friendly.
EDIT
I think what I'm trying to do in theory that is once the script scans the dir it puts it into an array called $files I then foreach loop it for all of the folders but where I get stuck now is how do I pass that $file into a new page ? and make it show the contents inside the folder :)
Thanks again and sorry super newbie here trying to learn!
Script File to generate list and click to files inside of each:
<?php
$files = array();
$dir = opendir('races/ob/');
// $dir = opendir('races/ob/');
while(false != ($file = readdir($dir))) {
if(($file != ".") and ($file != "..") and ($file != "index.php")) {
$files[] = $file; // put in array.
}
}
natsort($files); // sort.
// print.
foreach($files as $file) {
echo("<span class='txt-spacing'><a href='races/ob/$file'>$file</a> <br />\n</>");
}
?>
The simple function can do all for you
scandir(<path>);
It will give you list of all files in the directory.
I figured out my problem with some help from a friend. I hope others can use this to help out the community.
1) First thing is to list A directory of files on the index.php
2) Once the user clicks the generated folder, go into races.php and display the the results of the files listed inside the folder clicked.
Here is how it's done by passing a parameter in the URL
index.php
<?php
$files = array();
$dir = opendir('races/ob/');
// $dir = opendir('races/ob/');
while(false != ($file = readdir($dir))) {
if(($file != ".") and ($file != "..") and ($file != "index.php")) {
$files[] = $file; // put in array.
}
}
natsort($files); // sort.
// print.
foreach($files as $file) {
$url = "races/ob/$file";
$path = urlencode($url);
echo("<span class='txt-spacing'>
<a href='races.php?race=$path'>$file</a> <br />\n</>");
}
?>
races.php
<?php
$path = $_GET['race'];
// right here, you need the path prefix
$path = '/public_html' . urldecode($path); //SERVER PATH
// above here you need it
$objects = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path), RecursiveIteratorIterator::SELF_FIRST);
$fileData = array();
foreach($objects as $name => $object){
$fileinfo = pathinfo($name);
if (!is_dir($name) && isset($fileinfo['extension'])) {
$file = $fileinfo['basename'];
$fileData[] = $file;
}
}
?>
<?php foreach($fileData as $file): ?>
<a target = '_blank' href="http://crpu.ca<?php echo urldecode($_GET['race']) . '/' . $file; ?>"><?php echo "$file<br>"; ?></a>
<?php endforeach; ?>

Read File Names From folder Only Keep Files with .iso extention

I have a script that gets a string from a config file and based on that string grabs the file names of a folder.
I now only need the iso files. Not sure if the best way is to check for the .iso string or is there another method?
<?php
// Grab the contents of the "current.conf" file, removing any linebreaks.
$dirPath = trim(file_get_contents('current.conf')).'/';
$fileList = scandir($dirPath);
if(is_array($fileList)) {
foreach($fileList as $file) {
//could replace the below if statement to only proceed if the .iso string is present. But I am worried there could be issues with this.
if ($file != "." and $file != ".." and $file != "index.php")
{
echo "<br/><a href='". $dirPath.$file."'>" .$file."</a>\n";
}
}
}
else echo $dirPath.' cound not be scanned.';
?>
If you only need the files with an extension of .iso, then why not use:
glob($dirPath.'/*.iso');
rather than scandir()
try this:
if(is_array($fileList)) {
foreach($fileList as $file) {
$fileSplode = explode('.',$file); //split by '.'
//this means that u now have an array with the 1st element being the
//filename and the 2nd being the extension
echo (isset($fileSplode[1]) && $fileSplode[1]=='iso')?
"<br/><a href='". $dirPath.$file."'>" .$file."</a>\n":'');
}
}
If you want it in an OOP style you could use:
<?php
foreach (new DirectoryIterator($dirPath) as $fileInfo) {
if($fileInfo->getExtension() == 'iso') {
// do something with it
}
}
?>

Deleting all files from a folder using PHP?

For example I had a folder called `Temp' and I wanted to delete or flush all files from this folder using PHP. Could I do this?
$files = glob('path/to/temp/*'); // get all file names
foreach($files as $file){ // iterate files
if(is_file($file)) {
unlink($file); // delete file
}
}
If you want to remove 'hidden' files like .htaccess, you have to use
$files = glob('path/to/temp/{,.}*', GLOB_BRACE);
If you want to delete everything from folder (including subfolders) use this combination of array_map, unlink and glob:
array_map( 'unlink', array_filter((array) glob("path/to/temp/*") ) );
This call can also handle empty directories ( thanks for the tip, #mojuba!)
Here is a more modern approach using the Standard PHP Library (SPL).
$dir = "path/to/directory";
if(file_exists($dir)){
$di = new RecursiveDirectoryIterator($dir, FilesystemIterator::SKIP_DOTS);
$ri = new RecursiveIteratorIterator($di, RecursiveIteratorIterator::CHILD_FIRST);
foreach ( $ri as $file ) {
$file->isDir() ? rmdir($file) : unlink($file);
}
}
foreach (new DirectoryIterator('/path/to/directory') as $fileInfo) {
if(!$fileInfo->isDot()) {
unlink($fileInfo->getPathname());
}
}
This code from http://php.net/unlink:
/**
* Delete a file or recursively delete a directory
*
* #param string $str Path to file or directory
*/
function recursiveDelete($str) {
if (is_file($str)) {
return #unlink($str);
}
elseif (is_dir($str)) {
$scan = glob(rtrim($str,'/').'/*');
foreach($scan as $index=>$path) {
recursiveDelete($path);
}
return #rmdir($str);
}
}
$dir = 'your/directory/';
foreach(glob($dir.'*.*') as $v){
unlink($v);
}
Assuming you have a folder with A LOT of files reading them all and then deleting in two steps is not that performing.
I believe the most performing way to delete files is to just use a system command.
For example on linux I use :
exec('rm -f '. $absolutePathToFolder .'*');
Or this if you want recursive deletion without the need to write a recursive function
exec('rm -f -r '. $absolutePathToFolder .'*');
the same exact commands exists for any OS supported by PHP.
Keep in mind this is a PERFORMING way of deleting files. $absolutePathToFolder MUST be checked and secured before running this code and permissions must be granted.
See readdir and unlink.
<?php
if ($handle = opendir('/path/to/files'))
{
echo "Directory handle: $handle\n";
echo "Files:\n";
while (false !== ($file = readdir($handle)))
{
if( is_file($file) )
{
unlink($file);
}
}
closedir($handle);
}
?>
The simple and best way to delete all files from a folder in PHP
$files = glob('my_folder/*'); //get all file names
foreach($files as $file){
if(is_file($file))
unlink($file); //delete file
}
Got this source code from here - http://www.codexworld.com/delete-all-files-from-folder-using-php/
unlinkr function recursively deletes all the folders and files in given path by making sure it doesn't delete the script itself.
function unlinkr($dir, $pattern = "*") {
// find all files and folders matching pattern
$files = glob($dir . "/$pattern");
//interate thorugh the files and folders
foreach($files as $file){
//if it is a directory then re-call unlinkr function to delete files inside this directory
if (is_dir($file) and !in_array($file, array('..', '.'))) {
echo "<p>opening directory $file </p>";
unlinkr($file, $pattern);
//remove the directory itself
echo "<p> deleting directory $file </p>";
rmdir($file);
} else if(is_file($file) and ($file != __FILE__)) {
// make sure you don't delete the current script
echo "<p>deleting file $file </p>";
unlink($file);
}
}
}
if you want to delete all files and folders where you place this script then call it as following
//get current working directory
$dir = getcwd();
unlinkr($dir);
if you want to just delete just php files then call it as following
unlinkr($dir, "*.php");
you can use any other path to delete the files as well
unlinkr("/home/user/temp");
This will delete all files in home/user/temp directory.
Another solution:
This Class delete all files, subdirectories and files in the sub directories.

public function delete($path) {
if (is_dir($path)) {
array_map(function($value) {

Posted a general purpose file and folder handling class for copy, move, delete, calculate size, etc., that can handle a single file or a set of folders.
https://gist.github.com/4689551
To use:
To copy (or move) a single file or a set of folders/files:
$files = new Files();
$results = $files->copyOrMove('source/folder/optional-file', 'target/path', 'target-file-name-for-single-file.only', 'copy');
Delete a single file or all files and folders in a path:
$files = new Files();
$results = $files->delete('source/folder/optional-file.name');
Calculate the size of a single file or a set of files in a set of folders:
$files = new Files();
$results = $files->calculateSize('source/folder/optional-file.name');
<?
//delete all files from folder & sub folders
function listFolderFiles($dir)
{
$ffs = scandir($dir);
echo '<ol>';
foreach ($ffs as $ff) {
if ($ff != '.' && $ff != '..') {
if (file_exists("$dir/$ff")) {
unlink("$dir/$ff");
}
echo '<li>' . $ff;
if (is_dir($dir . '/' . $ff)) {
listFolderFiles($dir . '/' . $ff);
}
echo '</li>';
}
}
echo '</ol>';
}
$arr = array(
"folder1",
"folder2"
);
for ($x = 0; $x < count($arr); $x++) {
$mm = $arr[$x];
listFolderFiles($mm);
}
//end
?>
For me, the solution with readdir was best and worked like a charm. With glob, the function was failing with some scenarios.
// Remove a directory recursively
function removeDirectory($dirPath) {
if (! is_dir($dirPath)) {
return false;
}
if (substr($dirPath, strlen($dirPath) - 1, 1) != '/') {
$dirPath .= '/';
}
if ($handle = opendir($dirPath)) {
while (false !== ($sub = readdir($handle))) {
if ($sub != "." && $sub != ".." && $sub != "Thumb.db") {
$file = $dirPath . $sub;
if (is_dir($file)) {
removeDirectory($file);
} else {
unlink($file);
}
}
}
closedir($handle);
}
rmdir($dirPath);
}
public static function recursiveDelete($dir)
{
foreach (new \DirectoryIterator($dir) as $fileInfo) {
if (!$fileInfo->isDot()) {
if ($fileInfo->isDir()) {
recursiveDelete($fileInfo->getPathname());
} else {
unlink($fileInfo->getPathname());
}
}
}
rmdir($dir);
}
I've built a really simple package called "Pusheh". Using it, you can clear a directory or remove a directory completely (Github link). It's available on Packagist, also.
For instance, if you want to clear Temp directory, you can do:
Pusheh::clearDir("Temp");
// Or you can remove the directory completely
Pusheh::removeDirRecursively("Temp");
If you're interested, see the wiki.
I updated the answer of #Stichoza to remove files through subfolders.
function glob_recursive($pattern, $flags = 0) {
$fileList = glob($pattern, $flags);
foreach (glob(dirname($pattern).'/*', GLOB_ONLYDIR|GLOB_NOSORT) as $dir) {
$subPattern = $dir.'/'.basename($pattern);
$subFileList = glob_recursive($subPattern, $flags);
$fileList = array_merge($fileList, $subFileList);
}
return $fileList;
}
function glob_recursive_unlink($pattern, $flags = 0) {
array_map('unlink', glob_recursive($pattern, $flags));
}
This is a simple way and good solution. try this code.
array_map('unlink', array_filter((array) array_merge(glob("folder_name/*"))));

move all files in a folder to another?

when moving one file from one location to another i use
rename('path/filename', 'newpath/filename');
how do you move all files in a folder to another folder? tried this one without result:
rename('path/*', 'newpath/*');
A slightly verbose solution:
// Get array of all source files
$files = scandir("source");
// Identify directories
$source = "source/";
$destination = "destination/";
// Cycle through all source files
foreach ($files as $file) {
if (in_array($file, array(".",".."))) continue;
// If we copied this successfully, mark it for deletion
if (copy($source.$file, $destination.$file)) {
$delete[] = $source.$file;
}
}
// Delete all successfully-copied files
foreach ($delete as $file) {
unlink($file);
}
Please try this solution, it's tested successfully ::
<?php
$files = scandir("f1");
$oldfolder = "f1/";
$newfolder = "f2/";
foreach($files as $fname) {
if($fname != '.' && $fname != '..') {
rename($oldfolder.$fname, $newfolder.$fname);
}
}
?>
An alternate using rename() and with some error checking:
$srcDir = 'dir1';
$destDir = 'dir2';
if (file_exists($destDir)) {
if (is_dir($destDir)) {
if (is_writable($destDir)) {
if ($handle = opendir($srcDir)) {
while (false !== ($file = readdir($handle))) {
if (is_file($srcDir . '/' . $file)) {
rename($srcDir . '/' . $file, $destDir . '/' . $file);
}
}
closedir($handle);
} else {
echo "$srcDir could not be opened.\n";
}
} else {
echo "$destDir is not writable!\n";
}
} else {
echo "$destDir is not a directory!\n";
}
} else {
echo "$destDir does not exist\n";
}
tried this one?:
<?php
$oldfolderpath = "old/folder";
$newfolderpath = "new/folder";
rename($oldfolderpath,$newfolderpath);
?>
So I tried to use the rename() function as described and I kept getting the error back that there was no such file or directory. I placed the code within an if else statement in order to ensure that I really did have the directories created. It looked like this:
$tempDir = '/home/site/images/tmp/';
$permanentDir = '/home/site/images/' . $claimid; // this was stored above
mkdir($permanentDir,0775);
if(is_dir($permanentDir)){
echo $permanentDir . ' is a directory';
if(is_dir($tempDir)){
echo $tempDir . ' is a directory';
}else{
echo $tempDir . ' is not a directory';
}
}else{
echo $permanentDir . ' is not a directory';
}
rename($tempDir . "*", $permanentDir);
So when I ran the code again, it spit out that both paths were directories. I was stumped. I talked with a coworker and he suggested, "Why not just rename the temp directory to the new directory, since you want to move all the files anyway?"
Turns out, this is what I ended up doing. I gave up trying to use the wildcard with the rename() function and instead just use the rename() to rename the temp directory to the permanent one.
so it looks like this.
$tempDir = '/home/site/images/tmp/';
$permanentDir = '/home/site/images/' . $claimid; // this was stored above
mkdir($permanentDir,0775);
rename($tempDir, $permanentDir);
This worked beautifully for my purposes since I don't need the old tmp directory to remain there after the files have been uploaded and "moved".
Hope this helps. If anyone knows why the wildcard doesn't work in the rename() function and why I was getting the error stating above, please, let me know.
Move or copy the way I use it
function copyfiles($source_folder, $target_folder, $move=false) {
$source_folder=trim($source_folder, '/').'/';
$target_folder=trim($target_folder, '/').'/';
$files = scandir($source_folder);
foreach($files as $file) {
if($file != '.' && $file != '..') {
if ($move) {
rename($source_folder.$file, $target_folder.$file);
} else {
copy($source_folder.$file, $target_folder.$file);
}
}
}
}
function movefiles($source_folder, $target_folder) {
copyfiles($source_folder, $target_folder, $move=true);
}
try this:
rename('path/*', 'newpath/');
I do not see a point in having an asterisk in the destination
If the target directory doesn't exist, you'll need to create it first:
mkdir('newpath');
rename('path/*', 'newpath/');
As a side note; when you copy files to another folder, their last changed time becomes current timestamp. So you should touch() the new files.
... (some codes for directory looping) ...
if (copy($source.$file, $destination.$file)) {
$delete[] = $source.$file;
$filetimestamp = filemtime($source.$file);
touch($destination.$file,$filetimestamp);
}
... (some codes) ...
Not sure if this helps anyone or not, but thought I'd post anyway. Had a challenge where I has heaps of movies I'd purchased and downloaded through various online stores all stored in one folder, but all in their own subfolders and all with different naming conventions. I wanted to move all of them into the parent folder and rename them all to look pretty. all of the subfolders I'd managed to rename with a bulk renaming tool and conditional name formatting. the subfolders had other files in them i didn't want. so i wrote the following php script to, 1. rename/move all files with extension mp4 to their parent directory while giving them the same name as their containing folder, 2. delete contents of subfolders and look for directories inside them to empty and then rmdir, 3. rmdir the subfolders.
$handle = opendir("D:/Movies/");
while ($file = readdir($handle)) {
if ($file != "." && $file != ".." && is_dir($file)) {
$newhandle = opendir("D:/Movies/".$file);
while($newfile = readdir($newhandle)) {
if ($newfile != "." && $newfile != ".." && is_file("D:/Movies/".$file."/".$newfile)) {
$parts = explode(".",$newfile);
if (end($parts) == "mp4") {
if (!file_exists("D:/Movies/".$file.".mp4")) {
rename("D:/Movies/".$file."/".$newfile,"D:/Movies/".$file.".mp4");
}
else {
unlink("D:/Movies/".$file."/".$newfile);
}
}
else { unlink("D:/Movies/".$file."/".$newfile); }
}
else if ($newfile != "." && $newfile != ".." && is_dir("D:/Movies/".$file."/".$newfile)) {
$dirhandle = opendir("D:/Movies/".$file."/".$newfile);
while ($dirfile = readdir($dirhandle)){
if ($dirfile != "." && $dirfile != ".."){
unlink("D:/Movies/".$file."/".$newfile."/".$dirfile);
}
}
rmdir("D:/Movies/".$file."/".$newfile);
}
}
unlink("D:/Movies/".$file);
}
}
i move all my .json files from root folder to json folder with this
foreach (glob("*.json") as $filename) {
rename($filename,"json/".$filename);
}
pd: someone 2020?
