i have done something similar to that b4, i hope i can help...
there are (for me) two way to do it:
1)frame(all) / iframe(IE only)
2)table (template)
i would prefer table one, coz i don't like frame. so i would like to go further on the table one..
what you need are:
1) a template php
2) different php showing different content
the template should look like:
<?php
function display($content){
return
'<html>
<body>
<table>
<tr>
<td colspan="2">your banner code here</td>
</tr>
<tr>
<td>your table on the left</td>
<td>'.$content.'</td>
</tr>
</table>
</body>
</html>';
}
?>
for each content php should look like:
<?php
include(<relative path>.'template.php');
$content='each php have different content here';
display($content);
?>
p.s. the code have not been validate, there may be parse error in them, i just intent to show the logic
