What are the potential consequences of not being able to use additional functions in PHP scripts due to server restrictions?

If server restrictions prevent the use of additional functions in PHP scripts, it can limit the functionality and capabilities of your code. To solve this issue, you can try to find alternative functions or methods that achieve the same result without violating server restrictions. Additionally, you can reach out to your server administrator or hosting provider to see if they can adjust the restrictions to allow the necessary functions.

// Example of using an alternative function to get the current timestamp
$current_timestamp = time(); // Using time() function as an alternative to date() function
echo $current_timestamp;
