Would love to see a sample of the code once you get it working.

This is more of a PHP question, but given what I assume are negative
performance implications of string concatenation in a loop for a large
number of items, I've always used the following since I've come to PHP:

function whatever($echo=false) {
    $output = array();
    foreach(){
        $output[] = "something";
    }
    $output = implode('',$output);
    if ($echo)
        echo $output;
    return $output;
}

Anyone else has thoughts on this?
