PHP Program to remove all occurrences of an element from an array

<?php
//array with the string elements
$array = array('the','quick','brown','fox','quick','lazy','dog');

//array with the elements to be delete 
$array_del = array('quick');

//creating a new array without 'quick' element
$array1 = array_values(array_diff($array,$array_del));
//printing the $array1 variable
var_dump($array1);

//now we are removing 'the' and 'dog'
//array with the elements to be delete 
$array_del = array('the', 'dog');

//creating a new array without 'the' and 'dog' elements
$array2 = array_values(array_diff($array,$array_del));
//printing the $array2 variable
var_dump($array2);
?>
