MongoDB\BSON\Regex::__construct — Construct a new Regex

final public function MongoDB\BSON\Regex::__construct(string $pattern, string $flags = "")

pattern (string): The regular expression pattern.

注意:
The pattern should not be wrapped with delimiter characters.
flags (string): The » regular expression flags. Characters in this argument will be sorted alphabetically.

バージョン	説明
PECL mongodb 1.2.0	The `flags` argument is optional and defaults to an empty string. Characters in the `flags` argument will be sorted alphabetically when a Regex is constructed. Previously, the characters were stored in the order provided. MongoDB\Driver\Exception\InvalidArgumentException is thrown if `pattern` or `flags` contain null bytes. Previously, values would be truncated at the first null byte.

例1 MongoDB\BSON\Regex::__construct() example

<?php

$regex = new MongoDB\BSON\Regex('^foo', 'i');
var_dump($regex);

?>

上の例の出力は以下となります。

object(MongoDB\BSON\Regex)#1 (2) {
  ["pattern"]=>
  string(4) "^foo"
  ["flags"]=>
  string(1) "i"
}
