假设我有一个FooClass和一个bar()方法.在bar()方法内部，是否有任何方法可以判断它是否被静态调用，因此我可以对这两种情况进行不同的处理?

Let's say I have a FooClass with a bar() method. Inside of the bar() method, is there any way to tell if it's being called statically or not, so I can treat these two cases differently?

FooClass::bar();
$baz = new FooClass();
$baz->bar();

推荐答案

class FooClass {

    function bar() {
        if ( isset( $this ) && get_class($this) == __CLASS__ ) {
            echo "not static";
        }
        else {
            echo "static";
        }
    }

}

FooClass::bar();
$baz = new FooClass();
$baz->bar();
