PHP: Unlink All Files Within A Directory, and then Deleting That Directory

Question

I there a way I can use RegExp or Wildcard searches to quickly delete all files within a folder, and then remove that folder in PHP, WITHOUT using the "exec" command? My server does not give me authorization to use that command. A simple loop of some kind would suffice.

I need something that would accomplish the logic behind the following statement, but obviously, would be valid:

$dir = "/home/dir"
unlink($dir . "/*"); # "*" being a match for all strings
rmdir($dir);

Solution 1

Use glob to find all files matching a pattern.

function recursiveRemoveDirectory($directory)
{
    foreach(glob("{$directory}/*") as $file)
    {
        if(is_dir($file)) { 
            recursiveRemoveDirectory($file);
        } else {
            unlink($file);
        }
    }
    rmdir($directory);
}

Solution 2

Use glob() to easily loop through the directory to delete files then you can remove the directory.

foreach (glob($dir."/*.*") as $filename) {
    if (is_file($filename)) {
        unlink($filename);
    }
}
rmdir($dir);

Solution 3

The glob() function does what you're looking for. If you're on PHP 5.3+ you could do something like this:

$dir = ...
array_walk(glob($dir . '/*'), function ($fn) {
    if (is_file($fn))
        unlink($fn);
});
unlink($dir);

Solution 4

A simple and effective way of deleting all files and folders recursively with Standard PHP Library, to be specific, RecursiveIteratorIterator and RecursiveDirectoryIterator. The point is in RecursiveIteratorIterator::CHILD_FIRST flag, iterator will loop through files first, and directory at the end, so once the directory is empty it is safe to use rmdir().

foreach( new RecursiveIteratorIterator( 
    new RecursiveDirectoryIterator( 'folder', FilesystemIterator::SKIP_DOTS | FilesystemIterator::UNIX_PATHS ), 
    RecursiveIteratorIterator::CHILD_FIRST ) as $value ) {
        $value->isFile() ? unlink( $value ) : rmdir( $value );
}

rmdir( 'folder' );

Solution 5

Try easy way:

$dir = "/home/dir";
array_map('unlink', glob($dir."/*"));
rmdir($dir);

In Function for remove dir:

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($file, array('..', '.')))  {
                unlinkr($file, $pattern);
                //remove the directory itself
                rmdir($file);
                } else if(is_file($file) and ($file != __FILE__)) {
                // make sure you don't delete the current script
                unlink($file); 
            }
        }
        rmdir($dir);
    }

//call following way:
unlinkr("/home/dir");
