    $xml = simplexml_load_file($url);
    $mytweet = $xml->status[$tweetnumber]->text;
    $firstChar = substr($mytweet, 0, 1);
    //Exclude @ replies
    if($firstChar == "@"){
    //If this tweet is an @ reply move on to the previous one
    while ($firstChar == "@"){
    $tweetnumber++;
    $mytweet = $xml->status[$tweetnumber]->text;
    $firstChar = substr($mytweet, 0, 1);

    $mytweet = ereg_replace("[[:alpha:]]+://[^<>[:space:]]+[[:alnum:]/]","\\0", $mytweet);
    return $mytweet;
    }
    }
    }else{
    //If first tweet is not an @ reply output it
    $mytweet = ereg_replace("[[:alpha:]]+://[^<>[:space:]]+[[:alnum:]/]","\\0", $mytweet);
    return $mytweet;
    }
