Date pattern match

[glenelkins]

Hi

 

I have a pattern for REGEX:

 

$pattern = '%[0-9]{2,2}/[0-9]{2,2}/[0-9]{4,4}%';

 

This matches a date of birth, which should be in the format mm/dd/yyyy  the pattern matches 2/2/4  perfect. What would i need to change in the pattern to make sure that the mm part is not greater than 12 and the dd part is not greater than 31

Try this...

 

$pattern = '%(0?[1-9]{1}|1[0-2]{1})/([0-2]?[0-9]{1}|3[0-1]{1})/[0-9]{4,4}%';

Anything wrong with checkdate?

 

list($month, $day, $year) = explode('/', $date);
if (!checkdate($month, $day, $year)) {
echo 'invalid date';
}
