Unexpected syntax and parse error T_RETURN

Question

I have this function, and it returns Parse error: syntax error, unexpected T_RETURN. I would appreciate you help me. Thanks.

function getPin(){
    return substr(str_shuffle('ABCDEFGHIJKLMNOPQRSTUVWXYZABCDEFGHIJKLMNOPQRSTUVWXYZABCDEFGHIJKLMNOPQRSTUVWXYZ123456789123456789123456789'), 0, 6); ;
}
function validPin(){
    $pre = getPin();
    $sql = mysql_query("SELECT * FROM `images` WHERE `pin` = '$pre' ");
    $count = mysql_num_rows($sql);
    if($count > 0){
        return validPin();
    }else{
        return $pre;
    }
}

Answer 1

There might not be a closed bracket in earlier lines of code then. You should also clean up your double semicolon on line 11.
