regex to allow atleast one special character, one uppercase, one lowercase(in any order)

Question

Can anyone help me with a regex to allow atleast one special character, one uppercase, one lowercase.

This is what I have so far:

Answer 1

It can be done quickly by 3 regular expression.

function check($string){
   return    preg_match("/[`!%$&^*()]+/", $string) 
          && preg_match("/[a-z]+/", $string) 
          && preg_match("/[A-Z]+/", $string) ;
}

Dont forget to tweak the list of special characters. Because I dont know what characters you think are special.

I believe wasting a lot of time on a single line regex while you are not expert will not increase your productivity. This 3 regex solution will do just fine. It saves time.
