How can the issue of the Captcha validation always returning a false code be resolved in the PHP code provided?

The issue of the Captcha validation always returning a false code can be resolved by ensuring that the Captcha code is being properly generated and validated. One common mistake is not setting the Captcha session correctly or not comparing the user input with the Captcha code. By double-checking these aspects and ensuring proper implementation, the issue can be resolved. 

// Start the session
session_start();

// Generate a random Captcha code
$captcha_code = rand(1000, 9999);

// Store the Captcha code in the session
$_SESSION['captcha_code'] = $captcha_code;

// Validate the Captcha code entered by the user
if(isset($_POST['captcha']) && $_POST['captcha'] == $_SESSION['captcha_code']) {
    // Captcha validation successful
    echo "Captcha validation successful!";
} else {
    // Captcha validation failed
    echo "Captcha validation failed!";
}
