How can debugging techniques be used to identify errors in PHP scripts, specifically related to password hashing?

When debugging PHP scripts related to password hashing, one common error is using the wrong hashing algorithm or not properly comparing hashed passwords. To identify and fix this issue, you can use debugging techniques like printing variables, checking the return values of hashing functions, and comparing hashed passwords correctly using functions like password_verify. 

$password = "password123";
$hashedPassword = password_hash($password, PASSWORD_DEFAULT);

// Debugging technique: print the hashed password to check if it's generated correctly
echo "Hashed Password: " . $hashedPassword . "<br>";

// Simulate password verification process
$userInput = "password123";
if (password_verify($userInput, $hashedPassword)) {
    echo "Password is correct!";
} else {
    echo "Password is incorrect!";
}
