Can I use private instance methods as callbacks?

Question

My particular scenario involves doing some text transformation using regular expressions within a private method. The private method calls preg_replace_callback, but is seem

Answer 1

Yes, it seems you can:

test();


//this doesn't work
$result = preg_replace_callback('/test/', array(new a(), 'replaceCallback'), ' test test ');    
echo $result;

So it seems that preg_replace_callback(), or PHP's callback mechanism, is aware of the scope in which it was called.
