Is it advisable to use multiple hashing algorithms like MD5 and bcrypt in succession for password hashing in PHP, or is it better to stick to one secure algorithm like bcrypt?

It is generally not advisable to use multiple hashing algorithms in succession for password hashing in PHP. It is better to stick to a single secure algorithm like bcrypt, which is specifically designed for password hashing and is considered secure for this purpose. Using multiple algorithms can introduce unnecessary complexity and potential security vulnerabilities. 

// Using bcrypt for password hashing
$password = "password123";
$hashedPassword = password_hash($password, PASSWORD_BCRYPT);

// Verifying the password
if (password_verify($password, $hashedPassword)) {
    echo "Password is valid";
} else {
    echo "Invalid password";
}
