web safe colors

neigon

Hi
I just got stuck in my assignment. I am trying to use arrays and would appreciate if anybody could help. I would also like to use tables.

This is what i have done:

<title>Web Safe Colors</title>
<head>hello 216 colors</head>
<body>
<?
$redcolor= array (00,33,66,99,cc,ff);
$bluecolor=array ( 00,33,66,99,cc,ff);
$greencolor=array ( 00,33,66,99,cc,ff );
for( $redcolor=0; $redcolor <=6; $redcolor++ )

echo $redcolor[$redcolor];

echo $bluecolor[$bluecolor];
echo $greencolor[$greencolor];
?>

</body>

Could anybody please tell me where i went wrong?
Thanks
Neil

PS:I am still learning

blue928

in establishing an array, u want to use this format:

$redcolor = array ("00","33","66","99");

okay, now, to access these values, remember that the array elements are numbered being with 0 from right to left. so to access "00" you would say:

echo $redcolor[0];
// 33 would be:
echo $redcolor[1];
etc..

I see in your FOR() statement that you are trying to loop through the array. use the values in the [] brackets as what you will increment.. like this

for ( i=0; i<=6; i++ ) {
echo $redcolor;
}

this will loope through your array for you. if you don't want to manually count the number of elements in your array then you can put this before your for statement:
$count = count($redcolor);
then use this in the for statement:
i<=$count

hope this helps

HI Blue

Thanks for the help; but I'm still running into error messages:

echo "$bluecolor";
echo "<tr><th>00</td>

echo $greencolor;

echo "<tr><th>00</td>
<th>33</td>
<th>66</td>
<th>99</td>
<th>cc</td>
<th>ff</td>
</tr>"

?>
</body>

I am trying to create a table and set the cell background colors to RGB values generated by the loop. I know i am making a fundamental error somewhere. But don't have any clue at the moment where I'm wrong.

Any help is greatly appreciated.
Thanks
Neil
