Why can't I use a method non-static with the syntax of the methods static(class::method) ? Is it some kind of configuration issue?
class Teste { public function fun1() { echo 'fun1'; } public static function fun2() { echo "static fun2" ; } } Teste::fun1(); // why? Teste::fun2(); //ok - is a static method

One way for calling the same method both statically and non-statically is using the magic methods __call and __callStatic .
Similarly, a private static method can be called from a non-static method of the same class but a public static method e.g. main() can be called from anywhere.
But when we try to call Non static function i.e, TestMethod() inside static function it gives an error - “An object refernce is required for non-static field, member or Property 'Program. TestMethod()”. So we need to create an instance of the class to call the non-static method.
class A { public function doSomething(){ //doing something. } } require_once 'A. class. php'; class B { //Call the method doSomething() from the class A. }
PHP is very loose with static vs. non-static methods. One thing I don't see noted here is that if you call a non-static method, ns statically from within a non-static method of class C, $this inside ns will refer to your instance of C.
class A { public function test() { echo $this->name; } } class C { public function q() { $this->name = 'hello'; A::test(); } } $c = new C; $c->q();// prints hello This is actually an error of some kind if you have strict error reporting on, but not otherwise.
