Wildcard in PHP

[Anon]

Does anyone know of a wildcard symbol in PHP? I am trying to search through an array for a date '2002-03-*'. This would let me get all the values in the array within a given month and year.

[van__]

<?
$myArray = array("2002-3-4"=>"Joe Bob","2002-3-5"=>"Billy Bob","2002-2-30"=>"Jim Bob");

$timeStamp = "2002-3-+[0-9]{1}";

foreach ($myArray as $key=>$val) {
if (ereg($timeStamp,$key)) {
$results[$key] = $val;
}
}

print_r($results);
?>
