How do I Generate a JavaScript file with PHP when it is requested in an HTML program? I want a PHP program like this that runs on the server when a certain JavaScript file is requested. Example code:
<?php
If (requested("file:///C:/server/htdocs/javascriptgenerator.php") {
javascript-code-to-give-to-client = "function myFunction(){...";
}
?>
I know that was very fake code, but that is how I write when I don't know how to do it. I would also want this file to always be running on the server in case the file is requested. I also want to know how to just send the file as normal. I also want to know how to do this depending on the client.

The easiest way is to not actually use javascriptfile.js. Instead have a new php file called javascriptgenerator.php or something with the following code in:
<?php
header('Content-Type: text/javascript');
if($condition){
echo file_get_contents('js/javascript_file_a.js');
}
The header() line ensures that the browser will pick up that it's a JS file.
Using this in an HTML file is simple, just use this line of code in the <head> tag
<script type="text/javascript" src="javascriptgenerator.php"></script>
If you need to find out information about the client you can inspect the user agent, which you can then pass to the get_browser() function like this:
$user_agent = $_SERVER['HTTP_USER_AGENT'];
$browser_info = get_browser($user_agent);
Example get Browser Output (from PHP Manual):
Array
