PHP - Get keys from array

Introduction

We can get a list of the keys of the array with array_keys, and a list of its values with array_values:

Demo

<?php
    $properties = [ /*from w  w  w  .  j  a v a 2 s .c om*/
        'firstname' => 'T', 
        'surname' => 'R', 
        'house' => 'S' 
    ]; 
    $keys = array_keys($properties); 
    var_dump($keys); 
    $values = array_values($properties); 
    var_dump($values); 
?>
