PHP outputs source code on errors

Question

PHP

Good evening everyone.
I set up ispconfig on Ubuntu, in case of errors in php files, the source code of the script is displayed, for example
<?php echo '<pre>'; print_r($_SERVER)
Instead of an error, it displays
?php echo '<pre>'; print_r($_SERVER)
Already searched through the entire php.ini but there is no sense, can anyone come across how to fix it?

Answer 1

The problem was solved, the error turned out to be in FTP, when uploading files, the sign of the first sign < was cut off , now I'll see why

Answer 2

The problem is not php, but apache. It seems that the php interpreter does not even reach.

Answer 3

And the problem is not in the download mode? File Type Matching - Binary/ascii?

Answer 4

If you want to avoid similar problems in the future, catch errors!
