This one specifies the class (namespace) but is the same as the one above. The function is still called in the same way. The major difference is that this one names the class it's calling the function on. Changing the name of your class means having to change this call. Also, if you remove __construct from this clas syou would have to change it to use the parent's class name (or use parent:: instead). > > I'm asking in regards to making my PHP4 classes "forward thinking" in > regards to an upgrade to PHP5.
