How to Recursively Delete a Directory and Its Entire Contents (Files + Sub Dirs) in PHP

How do I recursively delete a directory and its entire contents (files + sub dirs) in PHP?

The user-contributed section in the manual page of rmdir contains a decent implementation:

 function rrmdir($dir) { 
if (is_dir($dir)) {
$objects = scandir($dir);
foreach ($objects as $object) {
if ($object != "." && $object != "..") {
if (is_dir($dir. DIRECTORY_SEPARATOR .$object) && !is_link($dir."/".$object))
rrmdir($dir. DIRECTORY_SEPARATOR .$object);
else
unlink($dir. DIRECTORY_SEPARATOR .$object);
}
}
rmdir($dir);
}
}

In PHP how do I recursively remove all folders that aren't empty?

From the first comment in the official documentation.

http://php.net/manual/en/function.rmdir.php

<?php

// When the directory is not empty:
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);
}
}

?>

Edited rmdir to rrmdir to correct typo from obvious intent to create recursive function.

Delete directory with files in it?

There are at least two options available nowadays.

  1. 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);
    }
  2. 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);

Remove all files, folders and their subfolders with php

<?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);
}
}
?>

Try out the above code from php.net

Worked fine for me

List all the files and folders in a Directory with PHP recursive function

Get all the files and folders in a directory, don't call function when you have . or ...

Your code :

<?php
function getDirContents($dir, &$results = array()) {
$files = scandir($dir);

foreach ($files as $key => $value) {
$path = realpath($dir . DIRECTORY_SEPARATOR . $value);
if (!is_dir($path)) {
$results[] = $path;
} else if ($value != "." && $value != "..") {
getDirContents($path, $results);
$results[] = $path;
}
}

return $results;
}

var_dump(getDirContents('/xampp/htdocs/WORK'));

Output (example) :

array (size=12)
0 => string '/xampp/htdocs/WORK/iframe.html' (length=30)
1 => string '/xampp/htdocs/WORK/index.html' (length=29)
2 => string '/xampp/htdocs/WORK/js' (length=21)
3 => string '/xampp/htdocs/WORK/js/btwn.js' (length=29)
4 => string '/xampp/htdocs/WORK/js/qunit' (length=27)
5 => string '/xampp/htdocs/WORK/js/qunit/qunit.css' (length=37)
6 => string '/xampp/htdocs/WORK/js/qunit/qunit.js' (length=36)
7 => string '/xampp/htdocs/WORK/js/unit-test.js' (length=34)
8 => string '/xampp/htdocs/WORK/xxxxx.js' (length=30)
9 => string '/xampp/htdocs/WORK/plane.png' (length=28)
10 => string '/xampp/htdocs/WORK/qunit.html' (length=29)
11 => string '/xampp/htdocs/WORK/styles.less' (length=30)

Deleting a directory with all of the files inside it

This will do it, just be careful you don't delete the whole server:

$dir='your/directory';
exec('rm -rf '.escapeshellarg($dir));

PHP Delete all files that are empty in a Directory and any sub directories

empty($file) doesn't check that the file referenced by $file is empty, it checks that the variable $file is empty. I.e., if $file contains an empty string "" or null then empty($file) will return true. Since your $file contains a non-empty string (the name of the file), empty($file) will always return false, regardless of the file contents. You want to check that filesize($file) is zero.
