Dynamically declaring Variable inside a class in php

Question

I have trouble dynamically declaring variables inside a class/object in PHP.

I have a class called Column and it receives an associative array of (names => values) of an unknown length.

I need the class variables to have the exact same name as in the array (and their values to match obviously).

Since Variable Variables method is a bit confusing, when you add on top of it the class/object declaration syntax, I feel I lost myself in it a bit.

I tried something like this:

function __construct($array)
    {
        foreach ($array as $key => $value)
        {
            $this->$key;
            $this->key=$value;          
        }
    }

i would usually not do this

$this->$key;

I thought $this->key would fit the syntax,but apparently I was wrong. If someone could help correct me it would very helpful.

Just use the {} syntax:

function __construct($array)
    {
        foreach ($array as $key => $value)
        {
            $this->{$key} = $value;          
        }
    }
