Description:
------------
file_get_contents emits a warning instead of an exception if the file does not exist!

This may be a good choice if the file is local where you can test for file existence. In case of remote files via http, this is quite not possible.

Since the silence operator does not work anymore, this raises undesireable errors in the logs.

Test script:
---------------
file_get_contents('https://www.google.com/rss.xml');

Expected result:
----------------
do not emit warnings. Just throw exceptions!

Actual result:
--------------
the emitted warning is filling the logs and does not help!

You may wish to either suppress the warning using "@" (if you do not care about it), or promote it to an exception using an error handler. The existing behavior will not be changed for backwards-compatibility reasons.

the @ operator does not work as it does in php 7.4
 [2021-05-12 10:00 UTC] nikic@php.net 
The @ operator no longer suppresses fatal errors in PHP 8. It does still suppress warnings, and file_get_contents() throws a warning, not a fatal error.

If @ does not work as expected in PHP 8, then this might be caused by a broken custom error handler. Please search for my_error_handler on https://www.php.net/manual/en/migration80.incompatible.php for an example of the necessary change.

sorry. Thanks a lot - I didn't realize this change!
