+## PHP Settings
+
+To increase memory_limit for specific part in code:
+  - In `/etc/opt/remi/php72/php-fpm.d/atom.conf` change `php_admin_value[memory_limit] = 2048M` to `php_value[memory_limit] = 2048M`, so that It can be overridden
+  - somewhere in the code, for example in a plugin, get and set it with: 
+  ```
+  echo ini_get('memory_limit');
+  ini_set('memory_limit', '4096M');
+  echo ini_get('memory_limit');
+  exit;
+  ```
