Can you use static constants in PHP?

Question

I expected the following to work but it doesn\'t seem to.

Answer 1

They're not static constants, just constants

class Patterns 
{ 
    const EMAIL = "/^([a-z0-9\+_\-]+)(\.[a-z0-9\+_\-]+)*@([a-z0-9\-]+\.)+[a-z]{2,6}$/ix"; 
    const INT = "/^\d+$/"; 
    const USERNAME = "/^\w+$/"; 
} 

echo Patterns::EMAIL;
