How can developers effectively debug PHP scripts to identify and resolve errors, such as staying on the index.php page after login attempts?

To debug PHP scripts and resolve errors like staying on the index.php page after login attempts, developers can use tools like error reporting, logging, and debugging extensions. They can also check for syntax errors, logic errors, and runtime errors in the code. Additionally, developers can use conditional statements to redirect users to a different page after successful login. 

// Check if login is successful
if ($login_successful) {
    // Redirect user to dashboard.php after successful login
    header("Location: dashboard.php");
    exit();
} else {
    // Display error message or stay on index.php page
    echo "Login failed. Please try again.";
}
