/* str_pad -- Pad a string to a certain length with another string (PHP4)
* string str_pad ( string input, int pad_length [, string pad_string [, int pad_type]])
* This functions returns the input string padded on the left, the right, or both sides to the specified
* padding length. If the optional argument pad_string is not supplied, the input is padded with spaces,
* otherwise it is padded with characters from pad_string up to the limit.
*
* Optional argument pad_type can be STR_PAD_RIGHT, STR_PAD_LEFT, or STR_PAD_BOTH. If pad_type is not
* specified it is assumed to be STR_PAD_RIGHT.
*
* If the value of pad_length is negative or less than the length of the input string, no padding takes
* place.
