i want to use this php script to know if my file.php contain errors , if it contain't errors i will not include it , else i include it .

Solution:

No, it's not possible. If you include a script in another script, and then execute that script, then PHP evaluates the whole combined script as if it was one file. So if there is a syntax error in any of the included scripts it will cause the whole thing to fail. That, naturally, happens before any of your other code can run. Your whole concept simply doesn't make sense. If you have syntax errors, test the scripts and fix the syntax errors before the code goes live.

And, as the comments suggest, if the real issue is that some files do not get deployed properly, then the solution is to fix the issues which are causing the deployment to fail.
