PHP is a server-side scripting language, which means it runs on the server and generates HTML code that is then sent to the client’s browser. JavaScript, on the other hand, is a client-side scripting language, which means it runs in the client’s browser. Therefore, in order to check if JavaScript is enabled in PHP, you need to use a technique that can detect whether the client’s browser has JavaScript enabled.
One common technique is to use the `$_SERVER[‘HTTP_USER_AGENT’]` variable. This variable contains the user agent string, which is a string that identifies the client’s browser. If the user agent string contains the word “JavaScript”, then it is likely that JavaScript is enabled in the client’s browser.
