How can PHP be used to verify a user's password input from a form field?

To verify a user's password input from a form field in PHP, you can compare the input password with the hashed password stored in your database. You can use the password_verify() function to compare the input password with the hashed password securely.

// Assuming $inputPassword is the password input from the form field
// Assuming $hashedPassword is the hashed password stored in the database

if (password_verify($inputPassword, $hashedPassword)) {
    // Password is correct
    echo "Password is correct.";
} else {
    // Password is incorrect
    echo "Password is incorrect.";
}
