How to import a php file so that only php is imported without html?

Question

PHP

Hi everyone again!
i have two files, let's say index.php and config.php. In index.php there is both php code and HTML markup, when I import the index.php file from config.php, even the markup is imported, but how can I import so that only php is imported?

Answer 1

The markup is taken out in separate files.

I have training - a project, a PHP dock and that's it.

The php doc has a set_error_handler that will catch most errors, and _{almost all} the rest can be caught using the register_shutdown_function.
After your error handler is triggered, calling debug_backtrace or Exception ->getTrace will not only allow you to see which line the error occurred on, but will show what happened before the error - which functions were called and with what parameters.
Have fun.
_{(yes, there are, of course, ready-made libraries for error handling, but for learning purposes, you can also write a bicycle)}

Answer 2

Well, you have to move what needs to be imported separately from the markup into a third file. And import everything from the third file to both index and config
