Sometimes, when we work with tables, we probably want to change the color for every row (<td>). There are probably many ways to do this, but I will describe the most simple of it - %.
So... let's say we have an array with 26 elements. But we don't really know that, so we do a `$count = count($myarray);`. Good! Now we know how many elements the array has, so let's get to the point.
We want to print every element on a line, in a row. So ... we will do something like the following:
<![CDATA[
<html>
<head><title>gee</title></head>
<body bgcolor="#FFFFFF">
<table width="100%">
]]>
<?
// hmm... let's say the array exists. as I said, it has 26 elements.
$array = array("1", "2", "3", "4", "5", "6", "7", "8", "9", "10",
"11", "12", "13", "14", "15", "16", "17", "18", "19", "20", "21",
"22", "23", "24", "26");
$count = count($array);
for($x=0;$x<=$count;$x++) { ?>
<tr><td><? echo $array[$x]; ?></td></tr>
<? } ?>
<![CDATA[
</table>
</body>
</html>
]]>
Eample:
gee
| 1 |
| 2 |
| 3 |
| 4 |
| 5 |
| 6 |
| 7 |
| 8 |
| 9 |
| 10 |
| 11 |
| 12 |
| 13 |
| 14 |
| 15 |
| 16 |
| 17 |
| 18 |
| 19 |
| 20 |
| 21 |
| 22 |
| 23 |
| 24 |
| 26 |
|
Now let's make the code look nice ;)
<![CDATA[
<html>
<head><title>gee</title></head>
<body bgcolor="#FFFFFF">
<table width="100%">
]]>
<?
// hmm... let's say the array exists. as i said, it has 26 elements.
$count = count($array);
for($x=0;$x<=$count;$x++) {
if(($x % 2) == 0) { $c = "#9999CC"; }
else { $c = "#CCCCCC"; }
?>
<tr><td bgcolor="<?= $c ?>">
<?= $array[$x]; ?>
</td></tr>
<? } ?>
<![CDATA[
</table>
</body>
</html>
]]>
Example:
gee
|
1 |
|
2 |
|
3 |
|
4 |
|
5 |
|
6 |
|
7 |
|

|
9 |
|
10 |
|
11 |
|
12 |
|
13 |
|
14 |
|
15 |
|
16 |
|
17 |
|

There you go.. I hope there are no code mistakes in my code. Happy coding!
