What do you really mean?
If your php generates output with some javascript embedded, there's no difference for client, whether a page is generated or not: for him it's just some html and js. You need only to check if you really generate some valid javascript. Look in the resulting code for errors.
And in case you want your js validation to be executed on the server side, there's of course no chance to get anything: js is for client, not for server.

the js is embedded within the php file. the same function on a normal html page works. the function checks to see that the required fields are not empty and then proceeds or a popup box is generated that tells the user what they need to do

now on the php file, i did the same and deliberately left afield empty but no pop up box appeared!!

hope it makes sense 🙂

As there's no difference for browser whether a document is static or was generated by a script, any problems should be in resulting html. Save it as html document and inspect it for errors in script. Maybe some element id got spoiled, or the script doesn't generate precisely that code which you meant to.
Good luck!
