array_pad -- Pad array to the specified length with a value
Description
array array_pad (array input, int pad_size, mixed pad_value)
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.
Example 1. Array_pad() example
$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
