 * strPad
 *
 * Pad a string to a certain length with another string

 * the output is padded with spaces, otherwise it is padded with characters from pad_string
 * up to the limit.
 *
 * The 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,
