Changelog

Version Description
8.0.0 This function returns true on success now. Previously, it returned the byte length of the matched string if a match for pattern was found in string and matches was passed. If the optional parameter matches was not passed or the length of the matched string was 0, this function returned 1.
7.1.0 mb_eregi() will now set matches to an empty array, if nothing matched. Formerly, matches was not modified in that case.
