array_pad

Description

array_pad() returns a copy of the input padded to size specified by pad_size with value pad_value. If pad_size is positive then the array is padded on the right, if it's negative then on the left. If the absolute value of pad_size is less than or equal to the length of the input then no padding takes place. It is possible to add most 1048576 elements at a time.

Example 1. array_pad() example <?php $input = array(12, 10, 9); $result = array_pad($input, 5, 0); // result is array(12, 10, 9, 0, 0) $result = array_pad($input, -7, -1); // result is array(-1, -1, -1, -1, 12, 10, 9) $result = array_pad($input, 2, "noop"); // not padded ?>
