] ) : intExecutes the regular expression match with multibyte support.
patternThe search pattern.
stringThe search string.
regs
If matches are found for parenthesized substrings of
pattern and the function is called with the
third argument regs, the matches will be stored
in the elements of the array regs.
If no matches are found, regs is set to an empty
array.
$regs[1] will contain the substring which starts at the first left parenthesis; $regs[2] will contain the substring starting at the second, and so on. $regs[0] will contain a copy of the complete string matched.
Returns the byte length of the matched string if a match for
pattern was found in string,
or FALSE if no matches were found or an error occurred.
If the optional parameter regs was not passed or
the length of the matched string is 0, this function returns 1.

mb_ereg() will now set regs to
an empty array, if nothing matched. Formerly,
regs was not modified in that case.
