PHP's website (http://www.php.net) has a great solution to displaying source
code. If you view the source code on their site you can see how they do it.
It's just a basic function to loop through the text and place in code to
highlight in various places. In fact here is that portion of code:
function highlight_php($code, $return = FALSE)
{
// Using OB, as highlight_string() only supports
// returning the result from 4.2.0
ob_start();
highlight_string($code);
$highlighted = ob_get_contents();
ob_end_clean();
// This should eventually be a php_syntax_check() call when we move to
PHP5
// But use this ugly hack for now to avoid code snippets with bad syntax
screwing up the highlighter
if(strstr($highlighted,"include/layout.inc</b>")) $highlighted =
"<pre>".htmlentities($code)."</pre>";
// Fix output to use CSS classes and wrap well
$highlighted = '<div class="phpcode">' . str_replace(
array(
' ',
'<br />',
'<font color="', // for PHP 4
'<span style="color: ', // from PHP 5.0.0RC1
'</font>',
"\n ",
' '
),
array(
' ',
"<br />\n",
'<span class="',
'<span class="',
'</span>',
"\n ",
' '
),
$highlighted
) . '</div>';
if ($return) { return $highlighted; }
else { echo $highlighted; }
}
This is how they called that function:
highlight_php(join("", file($page_name)));

Subject: [PHP-WIN] Presenting code snipetts in standard PHP colours
Hi all,
What is the easiest way to get a web page to list source code with standard
colour high-lighting (as used in my php_manual_el.CHM file and as you see
on various php web pages about the place).
Is there a class or a function or something that anyone knows of?
Thanks ... Ross
