What are best practices for securely storing and comparing passwords in a PHP application?

Storing passwords securely in a PHP application involves hashing the password before storing it in the database and using a secure method to compare the hashed password with the user input during login. The recommended approach is to use PHP's password_hash() function to hash the password and password_verify() function to compare the hashed password with the user input. 

// Hashing the password before storing it in the database
$password = "user_password";
$hashed_password = password_hash($password, PASSWORD_DEFAULT);

// Storing the hashed password in the database

// Comparing the hashed password with user input during login
$user_input_password = "user_input_password";

if (password_verify($user_input_password, $hashed_password)) {
    // Passwords match
    echo "Password is correct";
} else {
    // Passwords do not match
    echo "Password is incorrect";
}
