For some reason, you can't change PHP's properties (parameters). This plugin can help you.
Of course, it can only change PHP properties if your server allows it. In some cases, you may not see the PHP property you are interested in in this list, it simply does not have the right to change. In those cases, you can change the properties via PHP INI or .htaccess file.
It works with Joomla 3, 4 and 5.
After installing the plugin, go to Plugin Manager and activate this plugin: JMP PHP Settings.
