Variable not keeping value?

Recommended Posts

Why isn't the text this document displays, white? I have a variable representing each value of the rgb specification of the color white. I set the variable to 255 but the text always shows up black. Can anybody please explain why? Here's the code:
[code]<?php $colorNum=255; ?>
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
</head>

<body>
<p style="color: rgb(<?php $colorNum; ?>,<?php $colorNum; ?>,<?php $colorNum; ?>);">This be some text.</p>
</body>
</html>
[/code]

My bet would be that if you view the source of the file, it will look like this:
[code]
<p style="color: rgb(,,);">This be some text.</p>
[/code]

Change your line to this:
[code]
<p style="color: rgb(<?php echo $colorNum; ?>,<?php echo $colorNum; ?>,<?php echo $colorNum; ?>);">This be some text.</p>
[/code]

and it should work.
