Question

I am trying to add up the character length from an inserted URL. I have grabbed all the selected URLs from the database in an array and am trying to add them up in a foreach function.

function countLen($email) {

    $countLen = mysql_query("SELECT url FROM urls WHERE user='$email'");
    $resultLen = mysql_result($countLen, 0);

    foreach($resultLen as &$string) {


        $length = strlen($string);
        $totallen = ($totallen + $length);

        return $totallen;




    }





}

Answer 1

You could just do it all the summing in SQL:

function countLen($email)
{
    $res = mysql_query("SELECT SUM(LENGTH(url)) as 'sum' FROM urls WHERE user='$email'");
    return current(mysql_fetch_array($res));
}
