Extract zip files on the server on the fly and chmod

Upload zip file (ex. WordPress package) and extract.php to the same folder, then type the following:

http://path/to/extract.php?file=filename.zip

On success you will get "ZIP archive extracted" message.

extract.php

<?php
function recursiveChmod( $path, $filePerm = 0644, $dirPerm = 0755 ) { 
	if ( ! file_exists( $path ) ) {
		return( false );
	}

	if ( is_file( $path ) ) {
		chmod( $path, $filePerm );
	} elseif ( is_dir( $path ) ) {
		chmod( $path, $dirPerm );

		$foldersAndFiles = scandir( $path );
		$entries = array_slice( $foldersAndFiles, 2 );
		foreach( $entries as $entry ) {
			recursiveChmod( $path.DIRECTORY_SEPARATOR.$entry, $filePerm, $dirPerm );
		}
	}

	return( true );
}

$file = $_GET['file'];
$zip  = new ZipArchive();
if ( $zip->open( $file ) === TRUE ) {
    $zip->extractTo( __DIR__ );
    $zip->close();
    recursiveChmod( __DIR__, 0644, 0755 );
    echo 'ZIP archive extracted';
} else {
    echo 'ZIP archive extraction failed';
}
