The regular expression pattern.

The string being searched.

If matches are found for parenthesized substrings of$patternand the function is called with the third argument$regs, the matches will be stored in the elements of the array$regs. If no matches are found,$regsis 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.

返回值

Returns the byte length of the matched string if a match for$patternwas found in$string, or FALSE if no matches were found or an error occurred.

If the optional parameter$regswas not passed or the length of the matched string is0, this function returns1.
