TalkPHP - View Single Post - How to cater for missing input to a class

captainmerton · 08-26-2009, 02:53 PM

Here's an example:

My class:

PHP Code:


			
class SimpleClass

{

    public function __contruct($variable1,$variable2) {

        do some stuff with variables 1 and 2;

    }

}

My client code:

PHP Code:


			
$newobject = New SimpleClass($variable1);

This errors and the script stops executing because the class hasnt received the 2 variables required to instantiate the object. I have this option (which i dont want to do):

PHP Code:


			
if ((isset(variable1)) && (isset($variable2))) {

    $newobject = New SimpleClass($variable);

}

Is there a way I could handle this more elegantly? i.e. i want the class to be robust enough to handle idiots passing in junk data. I assume that is the point of object orientation.
