Are there any security risks associated with using PHP_SELF in the $_SERVER superglobal array, as suggested in the thread?

Using PHP_SELF in the $_SERVER superglobal array can pose a security risk as it can be manipulated by an attacker to inject malicious code. To mitigate this risk, it's recommended to use htmlspecialchars() function to sanitize the input before using it in your code. 

$script_name = htmlspecialchars($_SERVER['PHP_SELF']);
echo "The current script is: $script_name";
