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

How do I delete a directory and its entire contents (files and subdirectories) 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); 
   } 
 }


Building on The Pixel Developer's comment, a snippet using the SPL might look like:

$files = new RecursiveIteratorIterator(
    new RecursiveDirectoryIterator($dir, RecursiveDirectoryIterator::SKIP_DOTS),
    RecursiveIteratorIterator::CHILD_FIRST
);

foreach ($files as $fileinfo) {
    $todo = ($fileinfo->isDir() ? 'rmdir' : 'unlink');
    $todo($fileinfo->getRealPath());
}

rmdir($dir);

Note: It does no sanity checking and makes use of the SKIP_DOTS flag introduced with the FilesystemIterator in PHP 5.3.0. Of course, the $todo could be an if/else. The important point is that CHILD_FIRST is used to iterate over the children (files) first before their parent (folders).


Deletes all files and folders in the path.

function recurseRmdir($dir) {
  $files = array_diff(scandir($dir), array('.','..'));
  foreach ($files as $file) {
    (is_dir("$dir/$file") && !is_link("$dir/$file")) ? recurseRmdir("$dir/$file") : unlink("$dir/$file");
  }
  return rmdir($dir);
}


For *nix you can use a shell_exec for rm -R or DEL /S folder_name for Windows.


There is another thread with more examples here: A recursive remove directory function for PHP?

If you are using Yii then you can leave it to the framework:

CFileHelper::removeDirectory($my_directory);

function rrmdir($source, $removeOnlyChildren = false)
{
    if(empty($source) || file_exists($source) === false)
    {
        return false;
    }

    if(is_file($source) || is_link($source))

            {
                return false;
            }
        }
        else
        {
            if(unlink($fileinfo->getRealPath()) === false)
            {
                return false;
            }
        }

    }

    return true;
}


The 100% working solution

public static function rmdir_recursive($directory, $delete_parent = null)
  {
    $files = glob($directory . '/{,.}[!.,!..]*',GLOB_MARK|GLOB_BRACE);
    foreach ($files as $file) {
      if (is_dir($file)) {
        self::rmdir_recursive($file, 1);
      } else {
        unlink($file);
      }
    }
    if ($delete_parent) {
      rmdir($directory);
    }
  }


Example with glob() function. It will delete all files and folders recursively, including files that starts with dot.

delete_all( 'folder' );

function delete_all( $item ) {
    if ( is_dir( $item ) ) {
        array_map( 'delete_all', array_diff( glob( "$item/{,.}*", GLOB_BRACE ), array( "$item/.", "$item/.." ) ) );
        rmdir( $item );
    } else {
        unlink( $item );
    }
};


Enhanced @Artefacto 's solution - corrected typos and simplified code, working for both - empty && non-empty directories .

  function recursive_rmdir($dir) { 
    if( is_dir($dir) ) { 
      $objects = array_diff( scandir($dir), array('..', '.') );
      foreach ($objects as $object) { 
        $objectPath = $dir."/".$object;
        if( is_dir($objectPath) )
          recursive_rmdir($objectPath);
        else
          unlink($objectPath); 
      } 
      rmdir($dir); 
    } 
  }


Using DirectoryIterator and recursion correctly:

function deleteFilesThenSelf($folder) {
    foreach(new DirectoryIterator($folder) as $f) {
        if($f->isDot()) continue; // skip . and ..
        if ($f->isFile()) {
            unlink($f->getPathname());
        } else if($f->isDir()) {
            deleteFilesThenSelf($f->getPathname());
        }
    }
    rmdir($folder);
}


It seems that all other answers assume the path given to the function is always a directory. This variant works to remove directories as well as single files:

/**
 * Recursively delete a file or directory.  Use with care!
 *
 * @param string $path
 */
function recursiveRemove(string $path) {
    if (is_dir($path)) {
        foreach (scandir($path) as $entry) {
            if (!in_array($entry, ['.', '..'], true)) {
                recursiveRemove($path . DIRECTORY_SEPARATOR . $entry);
            }
        }
        rmdir($path);
    } else {
        unlink($path);
    }
}

EDIT: If you're picky (and you should be picky) you may want to add code to check for scandir(), rmdir() and unlink() returning an error and throw an exception if so.


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);
        }
    }
}


'simple' code that works and can be read by a ten year old:

function deleteNonEmptyDir($dir) 
{
   if (is_dir($dir)) 
   {
        $objects = scandir($dir);

        foreach ($objects as $object) 
        {
            if ($object != "." && $object != "..") 
            {
                if (filetype($dir . "/" . $object) == "dir")
                {
                    deleteNonEmptyDir($dir . "/" . $object); 
                }
                else
                {
                    unlink($dir . "/" . $object);
                }
            }
        }

        reset($objects);
        rmdir($dir);
    }
}

Please note that all I did was expand/simplify and fix (didn't work for non empty dir) the solution here: In PHP how do I recursively remove all folders that aren't empty?


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.


I use this code ...

 function rmDirectory($dir) {
        foreach(glob($dir . '/*') as $file) {
            if(is_dir($file))
                rrmdir($file);
            else
                unlink($file);
        }
        rmdir($dir);
    }

or this one...

<?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); 
  } 
?>


I juste made this code, from some StackOverflow discussions. I didn't test on Linux environment yet. It is made in order to delete a file or a directory, completely :

function splRm(SplFileInfo $i)
{
    $path = $i->getRealPath();

    if ($i->isDir()) {
        echo 'D - ' . $path . '<br />';
        rmdir($path);
    } elseif($i->isFile()) {
        echo 'F - ' . $path . '<br />';
        unlink($path);
    }
}

function splRrm(SplFileInfo $j)
{
    $path = $j->getRealPath();

    if ($j->isDir()) {
        $rdi = new RecursiveDirectoryIterator($path, FilesystemIterator::SKIP_DOTS);
        $rii = new RecursiveIteratorIterator($rdi, RecursiveIteratorIterator::CHILD_FIRST);
        foreach ($rii as $i) {
            splRm($i);
        }
    }
    splRm($j);

}

splRrm(new SplFileInfo(__DIR__.'/../dirOrFileName'));


function rmdir_recursive( $dirname ) {

    /**
     * FilesystemIterator and SKIP_DOTS
     */

    if ( class_exists( 'FilesystemIterator' ) && defined( 'FilesystemIterator::SKIP_DOTS' ) ) {

        if ( !is_dir( $dirname ) ) {
            return false;
        }

        foreach( new RecursiveIteratorIterator( new RecursiveDirectoryIterator( $dirname, FilesystemIterator::SKIP_DOTS ), RecursiveIteratorIterator::CHILD_FIRST ) as $path ) {
            $path->isDir() ? rmdir( $path->getPathname() ) : unlink( $path->getRealPath() );
        }

        return rmdir( $dirname );

    }

    /**
     * RecursiveDirectoryIterator and SKIP_DOTS
     */

    if ( class_exists( 'RecursiveDirectoryIterator' ) && defined( 'RecursiveDirectoryIterator::SKIP_DOTS' ) ) {

        if ( !is_dir( $dirname ) ) {
            return false;
        }

        foreach( new RecursiveIteratorIterator( new RecursiveDirectoryIterator( $dirname, RecursiveDirectoryIterator::SKIP_DOTS ), RecursiveIteratorIterator::CHILD_FIRST ) as $path ) {
            $path->isDir() ? rmdir( $path->getPathname() ) : unlink( $path->getRealPath() );
        }

        return rmdir( $dirname );

    }

    /**
     * RecursiveIteratorIterator and RecursiveDirectoryIterator
     */

    if ( class_exists( 'RecursiveIteratorIterator' ) && class_exists( 'RecursiveDirectoryIterator' ) ) {

        if ( !is_dir( $dirname ) ) {
            return false;
        }

        foreach( new RecursiveIteratorIterator( new RecursiveDirectoryIterator( $dirname ), RecursiveIteratorIterator::CHILD_FIRST ) as $path ) {
            if ( in_array( $path->getFilename(), array( '.', '..' ) ) ) {
                continue;
            }
            $path->isDir() ? rmdir( $path->getPathname() ) : unlink( $path->getRealPath() );
        }

        return rmdir( $dirname );

    }

    /**
     * Scandir Recursive
     */

    if ( !is_dir( $dirname ) ) {
        return false;
    }

    $objects = scandir( $dirname );

    foreach ( $objects as $object ) {
        if ( $object === '.' || $object === '..' ) {
            continue;
        }
        filetype( $dirname . DIRECTORY_SEPARATOR . $object ) === 'dir' ? rmdir_recursive( $dirname . DIRECTORY_SEPARATOR . $object ) : unlink( $dirname . DIRECTORY_SEPARATOR . $object );
    }

    reset( $objects );
    rmdir( $dirname );

    return !is_dir( $dirname );

}


Modified variant of @XzaR solution. It does remove empty folders, when all files are deleted from them and it throws exceptions instead of returning false on errors.

function recursivelyRemoveDirectory($source, $removeOnlyChildren = true)
{
    if (empty($source) || file_exists($source) === false) {
        throw new Exception("File does not exist: '$source'");
    }

    if (is_file($source) || is_link($source)) {
        if (false === unlink($source)) {
            throw new Exception("Cannot delete file '$source'");
        }
    }

    $files = new RecursiveIteratorIterator(
        new RecursiveDirectoryIterator($source, RecursiveDirectoryIterator::SKIP_DOTS),
        RecursiveIteratorIterator::CHILD_FIRST
    );

    foreach ($files as $fileInfo) {
        /** @var SplFileInfo $fileInfo */
        if ($fileInfo->isDir()) {
            if ($this->recursivelyRemoveDirectory($fileInfo->getRealPath()) === false) {
                throw new Exception("Failed to remove directory '{$fileInfo->getRealPath()}'");
            }
            if (false === rmdir($fileInfo->getRealPath())) {
                throw new Exception("Failed to remove empty directory '{$fileInfo->getRealPath()}'");
            }
        } else {
            if (unlink($fileInfo->getRealPath()) === false) {
                throw new Exception("Failed to remove file '{$fileInfo->getRealPath()}'");
            }
        }
    }

    if ($removeOnlyChildren === false) {
        if (false === rmdir($source)) {
            throw new Exception("Cannot remove directory '$source'");
        }
    }
}


Once you finish running tests , just remove # from the #unlink and #rmdir in the class .

<?php 
class RMRFiles {

        function __construct(){
        }

    public function recScan( $mainDir, $allData = array() )
    {

    // hide files
    $hidefiles = array(
    ".",
    "..") ;

    //start reading directory
    $dirContent = scandir( $mainDir ) ;

        //cycle through
        foreach ( $dirContent as $key => $content )
        {
            $path = $mainDir . '/' . $content ;

            // if is readable / file
            if ( ! in_array( $content, $hidefiles ) )
            {
            if ( is_file( $path ) && is_readable( $path ) )
            {
            #delete files within directory
            #unlink($path);
            $allData['unlink'][] = $path ;
            }

            // if is readable / directory
            else
            if ( is_dir( $path ) && is_readable( $path ) )
            {
            /*recursive*/
            $allData = $this->recScan( $path, $allData ) ;

            #finally remove directory
            $allData['rmdir'][]=$path;
            #rmdir($path);
            }
            }
        }

    return $allData ;

    }
