So here is my code, the problem is that i get strcmp() output as 5 when i enter the password 'malik' in both the fields when it should obviously be 0,
i will attach an image to make myself clear. Also, I tried using var_dump($upassword) and var_dump($ucpassword) and I got String(5) for both of them, so there are no whitespaces.

  • Check for any trailing whitespace character (such as tab, space etc) in either of the two password strings.

  • Please extract a Minimal, Complete, and Verifiable example from your code before even posting here. There's way too much code here and the interpretation "strcmp() doesn't work" is not helpful either. As a new user, make sure you read How to Ask and take the tour.

  • You should really be testing for zero(0) since that is what strcmp() returns on a match ... if(strcmp($upassword, $ucpassword) == 0){echo "All cool";}else{echo "Passwords do not Match"}

  • @Jamie_D This part is alright - if the passwords are different, then terminate the script

You are setting $ucpassword to an empty string. It should be like this:



if($uname == '' || $uemail == '' || $upassword == '' || $ucpassword == ''){
die("Please fill all the fields");
}
