Use array_map to simply delete files and directories in PHP

Don't talk nonsense, just paste the code. What this article embodies is conciseness

<?php

 

// Delete all empty directories under the directory 

array_map('rmdir', glob('*', GLOB_ONLYDIR));

 

// Delete all files in the directory 

array_map('unlink', array_filter(glob('*'), 'is_file'));

Implement array_column functionality using array_map:

$data = array(

    array(

        'a' => 'first a',

        'b' => 'first b'

    ),

    array(

        'a' => 'second a',

        'b' => 'second b'

    )

);

 

$array_column = array_map(function($element){

    return $element['a'];

}, $data);

 

print_r($array_column);
