Пример #1 MongoRegex::__construct() example
This example uses a regular expression to query for all documents with a username field starting (^) with an l and a vowel ([aeiouy]), case-insensitive (/i).
<?php
$luke_search = new MongoRegex("/^l[aeiouy]/i");
$cursor = $collection->find(array("username" => $luke_search));
?>

AFAICT, as of PHP 5.3.6, this function doesn't work correctly with any delimiter character other than plain slash (/), which is annoying if your pattern looks like a URL or file path for example (which itself may contain slashes you'll have to escape).
One can make use of the print_r($your_mongoregex_object) statement to ensure the pattern is recognized properly.
