It sounds like eval cannot be disabled via php.ini since it is not a real function?

Hi raytracy,

pls. don't rely on informations you found over the internet. The answer from @alexonb is absolut correct and forbids the usage of the PHP command "eval". Just be informed, that you might have several PHP.ini (s) on your server, especially, when you use additional PHP - versions.
If you don't trust the answer, just test it for yourself, once with the "disable_function" in your depending "php.ini" and once without it and see your log - files, to ensure, what the settings restricts.

I have tested it and found disable_function did not work.

Here is my work:
1. add disable_function = "eval" to /opt/plesk/php/5.6/etc/php.ini since I am using php 5.6
2. Create a php webpage from official php eval sample: http://php.net/manual/en/function.eval.php
3. Execute the php page and inspect the result page

I found the eval function always be evaluated what ever I have or have not add disable_function="eval" to php5.6 ini.
My system are CloudLinux 7.2, Plesk 12.5 mu#49

Is there any suggestion to correct it?

Hi raytracy,

due to the fact, that the "disable_functions" - option at your "depending php.ini" will not completely deactivate the "eval" - function, consider to use the "suhosin" - module.

Have a look at the new "How-To", I just created for this propose: => [How-To] Install suhosin - module and configure it ( suitable for multible PHP - versions )
