Delete recursive files in PHP

September 14, 2009, 11:54 PM

Many time when you are working with file sin php you can find this scenario: You need to erase a directory and all his content (another directories and files inside).

For doing this the easier way is using a recursive function that makes this work for us.

I tried few of them and they work, but my favourite one was found in php.net (currently the link doesn’t have the comment anymore :S)

function removeRessource($_target) {//remove the done file
    //file?
    if( is_file($_target) ) {
        if( is_writable($_target) ) {
            if( @unlink($_target) ) {
                return true;
            }
        }
        return false;
    }
    //dir recursive
    if( is_dir($_target) ) {
        if( is_writeable($_target) ) {
            foreach( new DirectoryIterator($_target) as $_res ) {
                if( $_res->isDot() ) {
                    unset($_res);
                    continue;
                }
                if( $_res->isFile() ) {
                    removeRessource( $_res->getPathName() );
                } elseif( $_res->isDir() ) {
                    removeRessource( $_res->getRealPath() );
                }
                unset($_res);
            }
            if( @rmdir($_target) )    return true;
        }
        return false;
    }
}

To use it just call the function with the given path, that’s all.
