Function to view HTML source of a dynamic generated content php page??

Hi,

I have created a simple newsletter form with a couple of text/img fields. All data is stored in a mysql db. I also created a preview function which just gets the right data based on the newsletter_id and uses a template.

Now i need to create a view html source function. I have tried this but i doesn't work

function getHTML(){
	ob_start();
$newsletter_id = 3;
	include('preview.php');
	$currentoutput = ob_get_clean();
	return $currentoutput;
}
$content = getHTML();
echo $content;

Code (markup):

But directing the browser to preview.php?newsletter_id=3 shows the newsletter ok

Any advice, tips

 

You will probable have to run a preg_replace on the $content ie: replace < with &lt; and > with &gt;

and then echo the content like this

<pre>
<?php
print_r ($content);
?>
</pre>

PHP:

You may or may not need the <pre> tags, try it first ?


EDIT:
Try this:

function pre($var) {
$replace = array('<' => '&lt;', '>' => '&gt;');
return strtr($var, $replace);
}
echo pre($content);

PHP:

You will most likely also need to replace quotes " and & so just add to the array
