Array to string

carbonxps

Hi all,

I've got this array:

array(3) { ["idx"]=> int(2) [0]=> array(5) { ["quantity"]=> int(4) ["product_id"]=> string(3) "122" ["parent_id"]=> string(3) "122" ["category_id"]=> string(2) "15" ["description"]=> string(0) "" } [1]=> array(5) { ["quantity"]=> int(1) ["product_id"]=> string(2) "77" ["parent_id"]=> string(2) "77" ["category_id"]=> string(2) "19" ["description"]=> string(0) "" } }

And I need to get the product id's into a string like:

122,77

I've tried everything with nothing getting close. Please any help would be great.

Thanks.

I would have done basically the same thing, except with this twist:

$idArray = array();
foreach($theArray as $element) {
   if(is_array($element) and isset($element['product_id'])) {
      $idArray[] = $element['product_id'];
   }
}
$productIdString = implode(',', $idArray);

Thanks that looks like the right track, but I can't quite get it working...


for($i = 0; $i < $cart["idx"]; $i++) {

			print_r($cart[$i]['product_id']);

			echo "<BR/>";
			implode(',', $cart) ;
}

The print_r command is outputting both the id's, but I can't get it to work with implode. Sorry I am very new to php.

Ah Sorry I pasted the wrong code:

for($i = 0; $i < $cart["idx"]; $i++) {
				$result=implode(',', $cart[$i]) ;
				echo $result;
}

This is not outputting the whole array seperated by commas which is great, but I only want the product ID, as soon as I try to specify a field of the array I get errors. I just need to add the product_id to the output. Is this the correct way for handling this?

You need to add the product id to the $cart array within the loop, then do the implode after the loop.
