Code Inspection: Dynamic method called as static
Reports static calls to dynamic class methods.
For classes having the magic method
__callStatic, a separate inspection severity and highlighting level can be set.
In PHP 5.6 and later, calling static methods dynamically is deprecated and generates an
E_DEPRECATED warning. As of PHP 7.0, calling a non-static method statically results in
$this being undefined inside the method. See OOP Basics (php.net) for details.
In the following example, the method
foo() is called as static while actually it is dynamic.
