[SOLVED] foreach list help needed

[spfoonnewb]

I have this function to list values from a form POST...

 

What it does right now is if there is only one posted it does not add the comma.

 

If there are more than one posted it adds the comma after each one..

 

What I want it to do is not add the comma on the LAST one.

 

<?php 

foreach ($_POST["eval"] as $eval) {
   		$arr[] = array($eval);
   	
}

foreach ($_POST["eval"] as $eval) {

$count = count($arr);

   		if ($count > 1) {
   			echo "$eval, ";
   		}
   		else {
   			echo "$eval";
   		}
}

?>

what i do is add the comma then remove it

 

IE

<?php
$tmp = "";
foreach ($_POST["eval"] as $eval) {
$tmp .= $eval.", ";
}
$tmp = trim($tmp,", ");
echo $tmp;
?>

 

hope that helps

I eventually got it to work with.. since it cant repeat numbers..

 

$get_end = end($arr);

    if ($event == $get_end[0]) {
   			echo "$eval";
   		}
   		elseif ($count > 1) {
   			echo "$eval, ";
   		}
   		else {
   			echo "$eval";
   		}
