A problem ignored before php

{Code...} loads a test. php file. This file is empty and only & amp; lt ;? Php? & Amp; gt ;. No error is reported. But if you write {code...} in this way, an error will be reported. Does include create a new php runtime environment? Or why?

Include is The middle part, without the php start Terminator

Php files should not be closed unless HTML content is included in them.

Your error message is not posted. it seems that this problem may be caused by other invalid characters following the Terminator.

Your code area is not well placed. What is your code?

 ?>

This is definitely wrong, and the syntax is incorrect. if not, it is recommended that you edit the problem again. include is equivalent to copying the include file. if you include invalid characters here, the problem may occur, you can also run test. php tests.

Supplement: As mentioned above, although include is a copy file, it should also pay attention to the scope. for details, see include and require in PHP.

After reading your updates, your syntax itself is wrong and will inevitably be wrong.

For more information about the end tag, see official instructions on PHP tag.

Include is not simply to plug the code into the file.

Php is an explanatory language. when reading include and other commands, it will load the opcodes of another file for execution. I think so.
