Re: note 11676 added to Classes and Objects

It is understandable that your original loop will not work, you are getting a *copy* of the object, not the original object itself. A loop such: for ($i=0; $i<count($header); $i++) $header[$i]->set_i('new string'); Will access the object directly, instead of the copy you get w/ foreach. Will add the comment above to your note. --- rich.ayotte@discoverniagara.com wrote: > Array of Objects > > First here is a simple class: > class text { > var $i; > function text($i = 'default') { > $this->i = $i; > } > > function set_i( $i ) { > $this->i = $i; > } > } > > Now create objects and put them in an array > $header[] = new text('foo'); > $header[] = new text('bar'); > > The following will NOT work: > > foreach($header as $i): > $i->set_i('new string'); > endforeach; > > You must do the following instead: > $j = 0; > foreach($header as $i): > $k = &$header[$j++]; > $k->set_i('new string'); > endforeach; > > It's quirky.
