is the path to return if rewrite is enabled. (eg: "/myalbum")

callUserFunction()

Wrapper to call a plugin or otherwise possibly undefined function or method to avoid themes breaking if the plugin is not active

callUserFunction(string|array<string|int, mixed> $function[, array<string|int, mixed>|mixed $parameter = array() ]) : mixed

Follows PHP's native call_user_func_array() but tries to catch invalid calls

Note: Invalid static calls to non static class methods cannot be catched unless the native PHP extension Reflection is available.

Parameters
$function : string|array<string|int, mixed>

A function name, static class method calls like classname::methodname, an array with a class name and static method name or a cass object and a non static class name

$parameter : array<string|int, mixed>|mixed = array()

Parameters of the function/method as one dimensional array. Alternatively you also add separate argments like the original function defines them
