Passing multiple checkbox results to PHP in on varible

Ok, I figured out how to give one variable multiple values dynamically.

But still having trouble getting PHP to recognize all the values in the array.

Giving multiple values to a variable was pretty easy. Just create a empty array and when a checkbox is clicked, populate that array by doing the following:

var ccbArray:Array = [];

       if(checkBox0.selected)
	{
		//trace("Mozza");
		ccbArray.push(14);
	}
	
	if(checkBox2.selected)
	{
		ccbArray.push(12);
	}
	
	if(checkBox3.selected)
	{
		ccbArray.push(13);
	}

The array values are sent in a variable as thus:

variables.myVar = ccbArray;

In ActionScript, when I trace the results of my array I get, for example, 12,13,14. A simple comma-delimited sequence of numbers. Now I just have to pass that to $_POST[‘myVar’]. PHP can’t handle that without a hack?
