+ * always look for the longest possible match first and then work its way down to individual characters.
+ *
+ * @param array $search list of strings or characters that need to be replaced
+ * @param array $replace list of strings or characters that will replace the corresponding values in $search
+ * @param string $subject the string on which this operation is being performed
