 ===== 3. Define PHP_INI_SCAN_DIR at the Server Level in the WebAdmin Console =====
-Using the PHP_INI_SCAN_DIR environment variable allows you to use a variable that can set a standard location for the php.ini file in each virtual host. Unlike the PHPRC environment variable, though, PHP_INI_SCAN_DIR allows the use of the global php.ini file with the addition of a per-user php.ini.

+In a control panel environment such as with cPanel, ea-phpxx will normally load the main php.ini, then scan additional .ini files, like in this example with ea-php73:
-For the control panel environment such as cpanel, ea-phpxx will normally load the main php.ini then scan additional xxx.ini for each php packages already, such as ea-php73 as the following:

-To avoid missing the above additional folder scanning from ''/opt/cpanel/ea-php73/root/etc/php.d'', you should specify PHP_INI_SCAN_DIR milti additional scanning folders instead of just one separating with '':''.
+To avoid missing any additional folders when scanning from ''/opt/cpanel/ea-php73/root/etc/php.d'', you should specify multiple additional scanning folders in ''PHP_INI_SCAN_DIR'', separating them with '':''.

 The variables available for use are:
-  - $VH_ROOT: the virtual host's home directory
+  - ''$VH_ROOT'': the virtual host's home directory
-  - $VH_NAME: the virtual host's domain
+  - ''$VH_NAME'': the virtual host's domain
-  - $VH_USER: the virtual host's user
+  - ''$VH_USER'': the virtual host's user
  **Note:**
-  * This method is not recommended if you replace Apache with suPHP. When replacing Apache with suPHP, the PHPRC environment variable is recommended.

-Starting from LSWS 5.3.x, LSWS may automatically configure external applications and script handlers for control panels, hence it may not have external applications or script handlers anymore. If you want to define ''PHPRC'' environment variable for all external applications, you can use ''PHP'' tab.

-===== 8. ''disable_functions'' can only be used in global php.ini and can not be overriden by additional user's local .user.ini/php.ini, nor .htaccess =====

-Please be aware, for security reason, ''disable_functions'' is unique and can not be used in .htaccess, user's local ''.user.ini/php.ini''. You should only apply ''disable_functions'' on global php.ini for LiteSpeed by modifying the value from ''/opt/cpanel/ea-phpxx/root/etc/php.ini'' on cPanel/WHM.  It would be a security flaw if a user can modify it freely, hence it has been restricted by design from PHP itself, not from LiteSpeed.
