Question

In my current project, I need to add a loop contents to an array where I can use it later. This is my code. I tried some way but they’re not working. Can anybody give a help to fix it:

for($i=0;$i<$max;$i++) {
    $pid = $_SESSION['cart'][$i]['productid'];
    $q = $_SESSION['cart'][$i]['qty'];
    $pname = get_product_name($pid);

    if($q == 0) { 
        continue;
    } else {
        $j = $i+1;
    }

I need to add the $pid to an array where I should be able to use implode(",", $pid)

Thanks

Answer 1

$pids=array();
for($i=0;$i<$max;$i++){
  $pid=$_SESSION['cart'][$i]['productid'];
  $pids[]=$pid;
  $q=$_SESSION['cart'][$i]['qty'];
  $pname=get_product_name($pid);
  if($q==0){ 
    continue;
  }else{
    $j = $i+1;
  }
}
echo implode(' - ',$pids);

You should be a little more clear about what your end result should be, I could be a bit more specific
