php - Get value separated by comma WordPress -

how value separated comma. used explode it. i've tried.

$get_item_desc = get_post_meta ($post->id, 'item_description', true);  $arr = explode(",", $get_item_desc); $item_string = ''; foreach($arr $val){         echo $get_items = $item_string.trim($val).' '; } 

sample input:

item 1, item 2, item 3

sample output:

desc-1: item 1 desc-2: item 2 desc-3: item 3

based on sample input/output, can use:

$get_item_desc = get_post_meta($post->id, 'item_description', true);  $arr = explode(',', $get_item_desc); $i = 1;  foreach($arr $val){     echo 'desc-' . $i . ': ' . trim($val) . ' ';     $i++; }
