array_pad

Definition and usage

array_pad() function inserts a specified number of elements with the specified value into the array.

Tip: If you set the size parameter to a negative number, the function inserts a new element before the original array (see example below).

Note: If the size parameter is less than the length of the original array, the function will not delete any elements.

Example

Example 1

Returns 5 elements and inserts the "blue" value into the new element of the array:

 <?php
$a = array ( "red" , "green" ) ;
print_r ( array_pad ( $a , 5 , "blue" ) ) ;
?>

Try it yourself

Example 2

Use negative size parameter:

 <?php
$a = array ( "red" , "green" ) ;
print_r ( array_pad ( $a , - 5 , "blue" ) ) ;
?>
