To view a list of all PHP capabilities on the server that your PHP website is hosted on, please follow the directions below:
Create a file called phpinfo.php and uploading it to the wwwroot folder. This plain text file should contain the following:
<?php // Show all information, defaults to INFO_ALL phpinfo(); ?>
Once saved (as "phpinfo.php") go to http://www.name-of-your-website.com/phpinfo.php and this will simply dump out to the screen all of the PHP info capabilities for that server.
