php date validation

I'm building a php form and just want to test a field to see if the date is in the proper format without using a function...

I know just enough php to get the form working...other than this...got the testing for a proper e-mail address working, but can't get this to work...

I've tried this, but it's not working...anyone? The format should be MM/DD/YYYY

Code:

---

$result=preg_match("/^(\d{2})/(\d{2})/(\d{4})$/",$date);
if(!$result){
        echo "Enter a valid date";
        exit;
}

---

I also tried:

Code:

---

$result=ereg("^(\d{2})/(\d{2})/(\d{4})+$",$date);

---

but I don't know enough about what the punctuation symbols ^,/,(,{ and [ represent to get it working correctly...

version 4.4.7

TIA

Try this:

PHP Code:

---

<?PHP
$date = "01/01/2008";

$result = preg_match("/^[0-9]{2}\/[0-9]{2}\/[0-9]{4}$/",$date);

if(!$result){
    echo "Enter a valid date";
    exit;
}
?>

Hi,

so 13/13/2009 is a valid date?
