Welcome to JavaRanch
Do you understand that PHP runs in the server and Javascript runs in the client (browser) so "calling JavaScript function from PHP" is meaningless? If you TellTheDetails with what exactly you need to get done, we can probably come up with a better useful suggestion.

I always use echo "<script> function(); </script>";

It doesn't work in the way you think it does. You don't even need to have an "echo"- just placing <script> function(); </script> outside <?php ?> tags does the same as what with "echo" does. Particularly, it 'prints' that fragment as a text in the HTML content, and your browser interprets the generated HTML and there is a Javascript snippet calling your function - that's now something like calling-JS-from-PHP.

If calling to a Javascript method in a separate file is all what you need, simply 'import' that Javascript file using <script src> in your <head> block, and then you can call its functions anywhere in the body as you always do.
 
I agree. Here's the link: http://aspose.com/file-tools
