array_pad

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.
