Description:
------------
for some reason, `ini_set` in FPM is causing a 500 error with absolutely no error reporting,

So I'm running PHP 7.4.2 via nginx using the PHP socket, this also happened with PHP 7.4.1

```
 index index.html index.htm index.php;

 location / {
      try_files $uri $uri/ =404;
 }

 location ~ \.php$ {
      include snippets/fastcgi-php.conf;
      fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
 }
```


Test script:
---------------
using phpMyAdmin Stable branch added `ini_set("display_errors", true);` to config.ini.php above the blowfish secret var set.


set error_report = E_ALL & display_errors = On to the php/7.4/php.ini then restarted php-fpm `service php7.4-fpm restart`

Expected result:
----------------
either error that ini_set is not allowed, or for the page to load and PHP to have accepted the ini_set directive.

Actual result:
--------------
I just get a blank white screen for a HTTP 500 error, absolutely no error information.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

additionally you could have a look at the error_log setting as it might provide more information. You should also try disabling any extensions to see if that helps

ok,

<?php ini_set("display_error", true);  echo "durrrr"; ?>

I would also say that not supporting or testing against one of the biggest applications to use PHP is a little lax in QA.

The fact is a gave a test scenario that is very easy to follow and take a couple of mins to set up not using some small obscure system.

<?php ini_set("display_error", true);  echo "durrrr"; ?>

this is a completly useless comment

* 1: display_error is wrong spelled
* 2: display_errors don't change the error_reporting
