Re: Re: Classes in PHP5 || Puzzling Problem || Trying to Set $this->$name = $value

Sounds like a PHP version problem. PHP 4 will output 0 and PHP 5 will give 1. The constructor must be named the same as the class name in PHP 4 for this to work. You can have both constructors in your class so it will work in both versions. - Frank > I don't know the details of your app, but you might want to reconsider a resdesign. > > Having said that, your code actually works for me.
