How to add a loop content to an array in php

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

I would suggest you initialize an array for your pids

$arr_pids = array()

and each time you want to add a pid to this array just use

array_push($arr_pids, $pid)

$pids = array();

foreach ($_SESSION['cart'] as $cart)
{
 $pids[] = $cart['productid'];
}

This will get you a $pids array.

Do you just mean this?

$pids = array();
for($i=0;$i<$max;$i++)
{
    $pid=$_SESSION['cart'][$i]['productid'];
    $q=$_SESSION['cart'][$i]['qty'];
    if($q==0)
    { 
        continue;
    }
    // optimization... don't do anything if quantity is 0.
    $pids[] = $pid;
    $pname=get_product_name($pid);
}
echo implode(',', $pids);

$pids=array();
for($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

initialiaze $pid as an array first

$pid = array();

Now in your loop add the values to it

$pid[] =$_SESSION['cart'][$i]['productid'];

note the square brackets with pid

after your loop you can extract the values from $pid

$someValue = $pid[0] * something';

I hope this is what u are looking for
