vraagje for loop

hey,

ik heb nu deze for loop:

[COLOR= #0000BB]<?php
$d[/COLOR] [COLOR= #007700]=[/COLOR] [COLOR= #0000BB]10[/COLOR][COLOR= #007700];[/COLOR]
[COLOR= #0000BB]$c[/COLOR] [COLOR= #007700]=[/COLOR] [COLOR= #0000BB]30[/COLOR][COLOR= #007700];[/COLOR]
[URL="http://www.php.net/for"]for[/URL][COLOR= #007700]([/COLOR][COLOR= #0000BB]$i[/COLOR] [COLOR= #007700]=[/COLOR] [COLOR= #0000BB]0[/COLOR][COLOR= #007700];[/COLOR] [COLOR= #0000BB]$i[/COLOR] [COLOR= #007700]<[/COLOR] [COLOR= #0000BB]$c[/COLOR][COLOR= #007700];[/COLOR] [COLOR= #0000BB]$i[/COLOR][COLOR= #007700]+=[/COLOR] [COLOR= #0000BB]$d[/COLOR][COLOR= #007700]){[/COLOR]
[URL="http://www.php.net/echo"]echo[/URL] [COLOR= #0000BB]$i[/COLOR]
?>

dan krijg ik:

Quote:
0
10
20
30

is er een manier om die 0 weg te laten? Voor elke vorm van $d (dus ook 3)

[COLOR= #0000BB]<?php
$d[/COLOR] [COLOR= #007700]=[/COLOR] [COLOR= #0000BB]10[/COLOR][COLOR= #007700];[/COLOR]
[COLOR= #0000BB]$c[/COLOR] [COLOR= #007700]=[/COLOR] [COLOR= #0000BB]40[/COLOR][COLOR= #007700];[/COLOR]
[URL="http://www.php.net/for"]for[/URL][COLOR= #007700]([/COLOR][COLOR= #0000BB]$i[/COLOR] [COLOR= #007700]=[/COLOR] [COLOR= #0000BB]10[/COLOR][COLOR= #007700];[/COLOR] [COLOR= #0000BB]$i[/COLOR] [COLOR= #007700]<[/COLOR] [COLOR= #0000BB]$c[/COLOR][COLOR= #007700];[/COLOR] [COLOR= #0000BB]$i[/COLOR][COLOR= #007700]+=[/COLOR] [COLOR= #0000BB]$d[/COLOR][COLOR= #007700]){[/COLOR]
[URL="http://www.php.net/echo"]echo[/URL] [COLOR= #0000BB]$i[/COLOR] [COLOR= #007700].[/COLOR] [COLOR= #DD0000]<br>[/COLOR][COLOR= #007700];
}[/COLOR] ?>

zo?

output=
10
20
30

ja daar was ik ook al opgekomen. Alleen als $d nu 3 is krijg je 13, 16, 19 ipv 3, 6, 9.

Ik heb het zelf al opgelost je moet namelijk.

[COLOR= #0000BB]<?php
$d[/COLOR] [COLOR= #007700]=[/COLOR] [COLOR= #0000BB]10[/COLOR][COLOR= #007700];[/COLOR]
[COLOR= #0000BB]$c[/COLOR] [COLOR= #007700]=[/COLOR] [COLOR= #0000BB]30[/COLOR][COLOR= #007700];[/COLOR]
[URL="http://www.php.net/for"]for[/URL][COLOR= #007700]([/COLOR][COLOR= #0000BB]$i[/COLOR] [COLOR= #007700]=[/COLOR] [COLOR= #0000BB]$d[/COLOR][COLOR= #007700];[/COLOR] [COLOR= #0000BB]$i[/COLOR] [COLOR= #007700]<[/COLOR] [COLOR= #0000BB]$c[/COLOR][COLOR= #007700];[/COLOR] [COLOR= #0000BB]$i[/COLOR][COLOR= #007700]+=[/COLOR] [COLOR= #0000BB]$d[/COLOR][COLOR= #007700]){[/COLOR]
[URL="http://www.php.net/echo"]echo[/URL] [COLOR= #0000BB]$i[/COLOR]
?>

gebruiken

Oh zo ik snapte al niet helemaal wat je met die 3 bedoelde
