Bug #80915 [NEW]: Taking a reference to $_SERVER hides it's values from phpinfo()
From: donatj at gmail dot com
Operating system: All
PHP version: 8.0.3
Package: Scripting Engine problem
Bug Type: Bug
Bug description:Taking a reference to $_SERVER hides it's values from phpinfo()
Description:
------------
$_SERVER disappeared from our admin phpinfo page, after a bit of poking
I figured
out a middleware we're using takes a reference to $_SERVER.
It only reads, doesn't write to it at all - but it breaks phpinfo.
This can be seen in my given example code where simply:
$foo =& $_SERVER;
breaks phpinfo's variable output
Test script:
---------------
<?php
echo "---- Expected Output ----\n\n";
\phpinfo(INFO_VARIABLES);
echo "\n\n---- Actual Broken Output ----\n\n";
$foo =& $_SERVER;
\phpinfo(INFO_VARIABLES);
echo "\n\n---- Proof that \$_SERVER isn't broken ----\n\n";
print_r($_SERVER);
Expected result:
----------------
