password_verify doesn't verify hash
The function password_verify(); takes two parameters; a non-hashed input, and a stored hash to compare it to. It hashes the non-hashed input automatically to compared it to the stored version. So your initial code was re-hashing an already hashed password. Should look like this:
$verify=password_verify($_POST['passwrd'],$row[2]);if($verify){ $_SESSION["usrname"]=$usrname; echo "Correct";}else { echo "user: " . $usrname. "<br>"; echo "pass: " . $hash. "<br>"; echo "db: " . $row[2]."<br>"; echo "Wrong Username or Password";}
You rehashed the password - just pass the plaintext password and your hash (from db) to password_verify and it works.
