Regular expression match with multibyte support

Beschreibung

mb_ereg ( string $pattern , string $string [, array &$regs ] ) : int

Executes the regular expression match with multibyte support.

Parameter-Liste

pattern

The search pattern.

string

The 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.

Rückgabewerte

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.

Changelog

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