PHP: Check if variable exist but also if has a value equal to something

Question

I have (or not) a variable $_GET[\'myvar\'] coming from my query string and I want to check if this variable exists and also if the value corresponds to somethi

Answer 1

Well, you could get by with just if($_GET['myvar'] == 'something') since that condition presumes that the variable also exists. If it doesn't, the expression will also result in false.

I think it's ok to do this inside conditional statements like above. No harm done really.
