If you want to delete an element in an array, you can use the unset directly, but the index of the array does not rearrange:

<?php  
$arr = Array (' A ', ' B ', ' C ', ' d ');
Unset ($arr [1]);
Print_r ($arr);

The result:

Array ([0] => a [2] => C [3] => D)

So how do you get the missing elements to be filled and the array will be indexed again? The answer is Array_splice ():

<?php  
$arr = Array (' A ', ' B ', ' C ', ' d ');  
Array_splice ($arr, 1,1);  
Print_r ($arr);

The result:

Array ([0] => a [1] => C [2] => D)
