Question

I have in database values like this

123456789
826438758
?[e-mail]
?[e-mail]

I am getting the value dynamically but I need to be able to find out if there is a ? in the value. If there is a question mark in the value I want to redirect them to some other place

I think we can do this with regex but not sure how

Answer 1

if (strpos($string, '?') === 0) {
  //redirect
  header("Location: http://www.example.com");
}

The === is important as it will return false when there is no question mark, and false == 0 is true.
