Question: I have this simple for loop to echo an array:

```
for ($i = 0; $i < count($director); $i++) {
   echo '<a href="person.php?id='.$director[$i]["id"].'">'.$director[$i]["name"].'</a>';
}

```

The problem here is that when more than one element is in the array then I get everything echoed without any space between. I want to separate each element with a comma except the last one.

I can't use `implode` so I'm looking for another solution

Answer: 
This should work. It's better I think to call `count()` once rather than on every loop iteration.

```
$count = count($director);
for ($i = 0; $i < $count; $i++) {
   echo '<a href="person.php?id='.$director[$i]["id"].'">'.$director[$i]["name"].'</a>';

   if ($i < ($count - 1)) {
      echo ', ';
   }
}

```
```
for ( $i=0 ; $i < count($arr)-1 ; $i++ )
{
    echo ( $arr[$i]."," );
}
echo ( $arr[count($arr)-1] );

```
