I was wondering if the codes below are the correct way to check for a street address, email address, password, city and url using preg_match using regular expressions?
And if not how should I fix the preg_match code?
preg_match ('/^[A-Z0-9 \'.-]{1,255}$/i', $trimmed['address']) //street address
preg_match ('/^[\w.-]+@[\w.-]+\.[A-Za-z]{2,6}$/', $trimmed['email'] //email address
preg_match ('/^\w{4,20}$/', $trimmed['password']) //password
preg_match ('/^[A-Z \'.-]{1,255}$/i', $trimmed['city']) //city
preg_match("/^[a-zA-Z]+[:\/\/]+[A-Za-z0-9\-_]+\\.+[A-Za-z0-9\.\/%&=\?\-_]+$/i", $trimmed['url']) //url
