Change PHP_INI_SYSTEM configuration settings

PHP_INI_SYSTEM level settings cannot be changed from .user.ini or ini_set function. To make change for PHP_INI_SYSTEM settings on Azure web app, follow the steps,

1. Add an App Setting to your Web App with the key PHP_INI_SCAN_DIR and value d:\home\site\ini

2. Create an settings.ini file using Kudu Console (http://<site-name> in the d:\home\site\ini directory.

3. Add configuration settings to the settings.ini file using the same syntax you would use in a php.ini file. For example, if you wanted to point the curl.cainfo setting to a *.crt file and set 'wincache.maxfilesize' setting to 512K, your settings.ini file would contain this text:

 ; Example Settings

4. Restart your Web App to load the changes
