Question

I have two stings

a, b, d, e

and

1, 52, 34, 56

I want combine two strings as

a/1, b/52, d/34, e/56

I wrote my code like that:-

  $result2 = mysql_query($query2);
  while($row2=mysql_fetch_array($result2)){
    $arr2 = explode(",",$row2['string1']);
    $arr1 = explode(",",$row2['string2']);
    for($i2 = 0; $i2 < count($arr1); $i2++) {
      $raw_str = "".$arr2[$i2]."/".$arr1[$i2].",";
      $query3 = "UPDATE table SET com_str='".$raw_str."' WHERE id='".$row2['id']."'";
      if (!mysql_query($query3))
      {
          die('Error: ' . mysql_error());
      }
    }
   }

my code just can store a last value only into databese:-

   e/56,

But I want store full string into database.

Thanks for advance

Try this code:

$result2 = mysql_query($query2);
while($row2=mysql_fetch_array($result2)){
    $arr2 = explode(",",$row2['string1']);
    $arr1 = explode(",",$row2['string2']);
    $raw_str = array();
    for($i2 = 0; $i2 < count($arr1); $i2++)
        $raw_str[] = $arr2[$i2].'/'.$arr1[$i2];
    $query3 = "UPDATE table SET com_str='".implode(',',$raw_str)."' WHERE id='".$row2['id']."'";
    if (!mysql_query($query3)){
        die('Error: ' . mysql_error());
    }

}

Also you should look into naming your variables.
