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

```
Here's my 2 lines solution 

```
// Create your Array
$cities = Array("Rome", "Florence", "Venice");

// implode them
$list = trim(implode (", ", $cities))  ;
// remove last comma
$list = substr ( $list,0 ,strlen( $list ) );

//check result
die ($list);

```
