What are the potential security risks of using cookies to prevent script execution on page reload in PHP?

Using cookies to prevent script execution on page reload in PHP can pose security risks such as potential cookie tampering or manipulation by malicious users. To mitigate these risks, it is recommended to use server-side validation and verification of the cookie data before executing any scripts. 

// Set a cookie to prevent script execution on page reload
$cookie_name = "prevent_script_execution";
$cookie_value = "true";
setcookie($cookie_name, $cookie_value, time() + 3600, "/");

// Verify the cookie value before executing any scripts
if(isset($_COOKIE[$cookie_name]) && $_COOKIE[$cookie_name] == "true"){
    // Execute scripts here
} else {
    // Handle unauthorized access or redirect to a different page
}
