Hosting Test Site Domain:
PHP8 - get_defined_functions()

This is a test of the PHP get_defined_functions function 'get_defined_functions()'.

This test utilizes a script which gets a count of the number of functions available on the server the hosting account is on. It then lists out those functions and links each function to where further information about the function can be found.

This test is especially useful in comparing PHP functionality from one server to another (TEST vs. PRODUCTION for example) because it displays the version of PHP installed on the server as well as the total number of functions which are available.
