PHP - best way to initialize an object with a large number of parameters and default values

Question

I\'m designing a class that defines a highly complex object with a ton (50+) of mostly optional parameters, many of which would have defaults (eg: $type = \'foo\'; $width

Answer 1

I use this on a few of my classes. Makes it easy to copy and paste for rapid development.

private $CCNumber, $ExpMonth, $ExpYear, $CV3, $CardType;
function __construct($CCNumber, $ExpMonth, $ExpYear, $CV3, $CardType){
    $varsValues = array($CCNumber, $ExpMonth, $ExpYear, $CV3, $CardType);
    $varNames = array('CCNumber', 'ExpMonth', 'ExpYear', 'CV3', 'CardType');
    $varCombined = array_combine($varNames, $varsValues);
    foreach ($varCombined as $varName => $varValue) {$this->$varName = $varValue;}
}

Steps to use:

1. Paste in and get the list of variables from your current __construct function, removing any optional parameter values
2. If you haven't already, paste that in to declare your variables for your class, using the scope of your choosing
3. Paste that same line into the $varValues and $varNames lines.
4. Do a text replace on ", $" for "', '". That'll get all but the first and last that you'll have to manually change
5. Enjoy!
