Is it possible to tell if a method in the parent class is called explicitly by parent:: as opposed to being called automatically because the sub class doesn't contain the method being called?

well, I'm not sure you can get it easily. anyway, I think you could follow one of this way, if you need a work-around:
example 1:
class Par { function printit($which = false) { // when you call this method, based on variable it tells how it was called if ($which) { echo "called with parent "; } else { echo "called with this "; } } } class Chi extends Par { function callParent() { parent::printit(TRUE); } function callFunction() { $this->printit(FALSE); } } $chi = new Chi(); $chi->callParent(); $chi->callFunction();
example 2:
class Par { function printit() { // get all functions in child class $child_methods = array_diff(get_class_methods("Chi") , get_class_methods("Par")); // if the function there is in child class, probably it was called from there if (in_array(__FUNCTION__, $child_methods)) { echo "called with child "; } else { echo "called with parent "; } } } class Chi extends Par { function callParent() { parent::printit(); } function callFunction() { $this->printit(); } } $chi = new Chi(); $chi->callParent(); $chi->callFunction();
