How can I easily remove the last comma from an array?

Question

Let\'s say I have this:

$array = array(\"john\" => \"doe\", \"foe\" => \"bar\", \"oh\" => \"yeah\");

foreach($array as $i=>$k)
{
echo $i.\'-\'.$

Assuming the array is an index, this is working for me. I loop $i and test $i against the $key. When the key ends, the commas do not print. Notice the IF has two values to make sure the first value does not have a comma at the very beginning.

foreach($array as $key => $value)
{
    $w = $key;
    //echo "
w: ".$w."
";// test text
    //echo "x: ".$x."
";// test text
    if($w == $x && $w != 0 )
    {
    echo ", ";
    }
    echo $value;
    $x++;
}
