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.

$result = array_pad($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 ?>
