Dynamic array name confusion

der100

I have this code:

	$arr = array("shape","quality","size","lengthOptions");
	foreach ($arr as $value) {
		$$value=array();
	}
	reset($arr);

	while($productRow=mysql_fetch_assoc($productQuery)) {

		foreach ($arr as $value) {

			if($value=="lengthOptions"){
				if(!in_array($productRow[$value],$$value)){
					$$value[]=$productRow[$value];
				}
			}

		}

However, it seems to die at the "$$value[]..." line (the code runs through if I comment that line out), giving me a blank white page,
any idea of what I'm doing wrong?

the code looks insane to me, what are you actully trying to achieve?

Create a number of arrays (in this case: "shape","quality","size","lengthOptions")

Then, while looping through the result set of a query, keys of the result set
will also be "shape","quality","size","lengthOptions" , assign those values to the array of the same name.

$shape[]=result_row[shape];
$quality[]=result_row[quality];

etc..

wouldn't a multi-dimensional array be easier.

Ya know, that actually sounds like a good idea!

Thanx
