"function"??? Did you mean action (or method)?
Personally, it sounds strange to me. Could you tell
us what you're trying to do?
I suggest you study a little bit the object-oriented
paradigm and the web architecture. It seems that
you're thinking in a desktop/structured way, so using
the incorrect approach to the problem in the web/oop
paradigm.
Once I've said that, about your specific question...
(with comments)
function recfunction($param1, $param2)
// need to specify the variables with the $ sign.
{
if($condition)
// is the same and a bit more readable than if($condition == true)
{
$this->recfunction($param1, $param2);
// the correct syntax is something like this, not sure if it
should work... ;-(
//
// As a design tip, if I see an action in a controller I
expect it should be
// called by the browser, not to be recursivelly called inside the code
// even in that case, maybe you have considering converting your
// logic to iteractive instead of a recursive approach. Or, in another
// point of view, make a recursive call to a private method instead of
// the same action itself. Something like:
//
// function myAction($p1, $p2) {
// $this->_recmethod()
// //...
// function _recmethod() {
// if( $condition ) $this->_recmethod()
// }
}
}
Pay attention that these actions did not return any
value, so you could easily stay in a infine loop.
Did I say that sounds strange to me?
Best regards.
