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.
