PHP正则表达式验证生日

Question

Im having difficulties figuring out how to do the following preg_match in php. I have a HTML form where the user can enter his or hers birthdate by day, month & year.

How do i validate the following Day: make sure it's a number between 1 and 31, actually between 01 and 31 Month: make sure it's a number between 1 and 12, actually between 01 and 12 Year: make sure it's a number between 1800 and 2012, actually between 1800 and 2012

if (preg_match( ????? )) {
     echo " SUCCESS";
} else { 
     echo " ERROR";
} 

Thanks...

Answer 1

Checkdate needs 3 different parameters, for validating one input with preg_match, use pattern:

(0[1-9]|[12][0-9]|3[01])[- /.](0[1-9]|1[012])[- /.]((?|19|20)\d\d)

it validates correct date in style dd-mm-yyy and dd.mm.yyyy and dd/mm/yyyy and if you want, it also parses values out for each parameter

Answer 2

您可以通过checkdate()函数执行此操作
