Here's what I want to do:
$clsName = substr(md5(rand()),0,10); //generate a random name
$cls = new $clsName(); //create a new instance
function __autoload($class_name)
{
//define that instance dynamically
}
Obviously this isn't what I'm actually doing, but basically I have unknown names for a class and based on the name, I want to generate the class with certain properties etc.
I've tried using eval() but it is giving me fits over private and $this-> references...
//edit
Ok, obviously my short and sweet "here's what I want to do" caused massive strife and consternation amongst those who may be able to provide answers. In the hope of getting an actual answer I'll be more detailed.
I have a validation framework using code hints on the site I maintain. Each function has two definitions
function DoSomething($param, $param2){
//code
}
function DoSomething_Validate(vInteger $param, vFloat $param2){
//return what to do if validation fails
}
I'm looking to add a validator for primary keys in my database. I don't want to create a separate class for EVERY table (203). So my plan was to do something like
function DoSomething_Validate(vPrimaryKey_Products $id){ }
Where the __autoload would generate a subclass of vPrimaryKey and set the table parameter to Products.
Happy now?
This is almost certainly a bad idea.
I think your time would be better spent creating a script that would create your class definitions for you, and not trying to do it at runtime.
Something with a command-line signature like:
./generate_classes_from_db <host> <database> [tables] [output dir]
