copied!<p>Testing isset($this) wasn't working for me, as mentioned by troelskn "$this will be set as the callers context."</p> <pre><code>abstract class parent { function bar() { if( isset( $this ) ) do_something(); else static::static_bar(); } function static static_bar() { do_something_in_static_context(); } } class child extends parent { ... } $foo = new child(); $foo->bar(); //results in do_something() child::bar(); //also results in do_something() </code></pre> <p>In my case, I have a parent class with a object and static context function that performs the same task within a child class. isset( $this ) was always returning true, however, I noticed that while $this switches between being class child in object context and calling(?) class on static context, the wonderful <code>__class__</code> magic constant, remained as class parent!</p> <p>Shortly there-after finding the function is_a, we can now test if we're in static context:</p> <pre><code>if( is_a($this, __CLASS__) ) ... </code></pre> <p>Returns true on object context, false on static context.</p> <p>Please test for your own implementations, as I'm only testing this for my specific scenario (a unique case of inheritance calling) in 5.3. </p> <p>Unfortunately (for my case) I am yet unable to find a way to call the <code>static_bar()</code> since $this and static are referring to a separate class, and <code>__class__</code> is referring to the parent class. What I need is a way to call child::static_bar()...</p>
