Question

How do I get the following code not to blow up in my face?

<?php 

    class abc{
    }
    abc::$someDynamicVariable
?>

I don’t really want to declare the variable before hand, and was hoping I could declare it in the __construct function ( javascript functions’ arguments array anyone? )

The error I get is:

Fatal error: Access to undeclared static property: abc::$someDynamicVariable in

You may use PHPs Magic Methods __set()and __get() to set/get properties dynamic which do not exist so far.

Here is an example:

class Foo {
    private $data = array();

    public function __set($key, $value) {
        $this->data[$key] = $value;
    }

    public function __get($key) {
        return $this->data[$key];
    }
}

$foo = new Foo();
$foo->something = "bla"; // using magic __set()

echo $foo->something; // using magic __get()
