Array Manipulation

[les48]

Ok guys... I got a quick array problem. I've spent some time on this and I've about pulled out my hair.

I have a 2D array, that I would like to transform into another 2D array. Such as....

This is what i start with......

$arrayVar[0][id] = 34;
$arrayVar[0][name] = 'bob';

$arrayVar[1][id] = 12;
$arrayVar[1][name] = 'mary';

$arrayVar[2][id] = 6;
$arrayVar[2][name] = 'bob';

$arrayVar[3][id] = 7;
$arrayVar[3][name] = 'jo';

$arrayVar[4][id] = 99;
$arrayVar[4][name] = 'jo';

$arrayVar[5][id] = 73;
$arrayVar[5][name] = 'mary';

$arrayVar[6][id] = 81;
$arrayVar[6][name] = 'bob;

And I want to get this.....

$arrayNew[0][id] = '34, 6, 81';
$arrayNew[0][name] = 'bob';

$arrayNew[0][id] = '12, 73';
$arrayNew[0][name] = 'bob';

$arrayNew[0][id] = '7, 99';
$arrayNew[0][name] = 'bob';

Basically I want all unique names to have all their id's concatenated into one string. Make sense? Anyways, if someone can help I'd be much appreciated, as this has been a pain in the butt. I've tried doing foreach loops, sort, ksort but I always get stuck on the grouping of the ids.

Any and all ideas, functions or suggestions are welcome.

Thanks!!!

for ($i=0; $i<count($arrayVar); $i++) {
	if (!$tmp[$arrayVar[$i]['name']]) {
		$tmp[$arrayVar[$i]['name']] .= $arrayVar[$i]['id'];
	} else {
		$tmp[$arrayVar[$i]['name']] .= ','.$arrayVar[$i]['id'];
	}
}
print_r($tmp);
echo "<br>";

$i = 0;
foreach($tmp as $nm => $id) {
	$arrayNew[$i]['id'] = $id;
	$arrayNew[$i]['name'] = $nm;
	$i++;
}
print_r($arrayNew);
