How can different hashing algorithms impact the comparison of hashed passwords in PHP?

When comparing hashed passwords in PHP, it is important to ensure that both the hashing algorithm and the salt used for hashing are consistent. If different hashing algorithms are used to hash the passwords, the comparison will fail as the hashes will not match. To solve this issue, always use the same hashing algorithm and salt when hashing and comparing passwords.

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

// Storing hashed password in database

// Comparing hashed password
$user_input = "password123";
if (password_verify($user_input, $hashed_password)) {
    echo "Password is correct!";
} else {
    echo "Password is incorrect!";
}
