How do I dynamically invoke a class method in PHP?

Question

How can I dynamically invoke a class method in PHP? The class method is not static. It appears that

call_user_func(...)

only works with st

Answer 1

As of PHP7, you use an array-like way:

// Static call only
[TestClass::class, $methodName](...$args);

// Dynamic call, static or non-static doesn't matter
$instance = new TestClass;
[$instance, $methodName](...$args);

Just replace the class name with TestClass, the method name with $methodName and the method arguments with ...$args. Note that, in the later case, it doesn't matter that the method is static or non-static; PHP will call it automatically.
