I have some classes from which I create objects. In the __construct function I check the properties. If they do not match I would like to delete the created object. 

$example = new example('Value 1', 2, false);


foreach (get_object_vars($this) as $propertie => $value) {
    if (empty($value)) {
        // unset(); What i have to insert in unset() ?  
    }
}

Thanks!

    possible duplicate of [\_\_destruct in \_\_construct?](http://stackoverflow.com/questions/8593308/destruct-in-construct). This post details several options to do it the "right" way – Clément Malet Aug 14 '14 at 11:58

    You can't "cancel" object instantiation when you're inside `__construct()` function. Either raise an exception in constructor or create factory which will arrange all instantiation routines & dependencies for you – Alma Do Aug 14 '14 at 11:58

You need to unset the created object.

Don't do this in your constructor, do it where you're creating the obj.

What you can do to centralize this code is to build a Factory. You could just tell that factory then that you want an obj of the type example with these properties set val1, val2, val3....

Then the factory would run the code below and return the obj if everything is fine, if not you could give out an error message which explains what went wrong, like property wasn't set or something. Then you could react properly to it.

$example = new example('Value 1', 2, false);

foreach (get_object_vars($example) as $propertie => $value) {
    if (empty($value)) {
        unset($exampe);
        break; //This stops the foreach
    }
}
