Question

I have a simple foreach loop which enters data in a 2D array:

    foreach ($query as $row){

        if (!isset($sites[$row->site])){ $sites[$row->site] = array(); }
        if (!isset($sites2[$row->site])){ $sites2[$row->site] = array(); }

        if ($row->type == 1){
        $sites[$row->site][] = array($row->data1, $row->data2);
        } else {
        $sites2[$row->site][] = array($row->data1, $row->data2);
        }
    }

I need a minimum of 20 entries in the array’s ($sites and $sites2).

So if the query has lets say 5 rows, I want to reiterate the loop, repeating the 5 existent rows (inserting them inside the arrays) until the arrays reach 20 rows.

Any ideas?

try this:

$rows=0;
$haveDuplicated=false;
while($rows<20){
   foreach ($query as $row){
     if (!isset($sites[$row->site])){ $sites[$row->site] = array(); }
     if (!isset($sites2[$row->site])){ $sites2[$row->site] = array(); } 

     if ($row->type == 1){
       $sites[$row->site][] = array($row->data1, $row->data2);
     } else {
       $sites2[$row->site][] = array($row->data1, $row->data2);
     }
     $rows++;
     if ($rows>=20 && $haveDuplicated) break;
   }
   $haveDuplicated=true;
}
