sizeof($row); viser forkert
Hejsa har det her script hvor jeg har en line der hedderif ( sizeof($row) == 0 ) { // There was nothing in the DB
?>
<tr>
<td>Der er ikke oprettet nogen link endnu!</td>
<tr>
Men selvom db' en er tom returnere sizeof($row) 1 og hvorfor gør den det her er scriptet
Ps. der kommer et spm efter der er svaret på dette derfor 50 point
