php code parser - stripping html tags

mfacer

hey,

I'm trying to create some PHP Code which will allow me to create a "text only" page of my website...

I've found part of the code on PHP.net in the code notes part...

...here it is!

$handle = fopen($_GET['file'], "r");
	$contents = fread($handle, filesize($_GET['file']));


function removeEvilTags($source)
{
   $allowedTags='<a><br><b><h1><h2><h3><h4><i>' .
			 '<li><ol><p><strong><table>' .
			 '<tr><td><th><u><ul><html><body><title><head>';
   $source = strip_tags($source, $allowedTags);
   return $source;
}

$text = removeEvilTags($contents);

echo $text;

I call the parser like this

parser.php?file=index.php

the proplem is, index.php has includes, such as

when I load in index.php the include header part isnt included... how can I get the index.php file to load as a complete page, THEN parse it?

thanks...

Don't think you can. You'll have to extract all the names of included or required files and parse them seperately.

I guess I could use the $content then search for the includes... somehow doing it character by character... or tag by tag.. then once I find an include, read that file in....?

ob_start();

include $_GET['file'];


$contents = ob_get_contents();

ob_end_clean();

$text = removeEvilTags($contents);

echo $text;

you could also look at preg_replace if thats not what you wanted.

worked perfectly!!
I need to change any of the URLS to include the parser... eg:

the current menu URL is: about.php ... I need to turn that in to parser.php?file=about.php

and if the URL has an [url]HTTP://[/url] in it, it's an external one, so make it open _blank

.....any ideas?! cos I dont know where to start!!

preg_replace()

Nice fix rhefeld. Did not think about output buffering at all.

cheers.. I've used str_replace as I dont really know what to do with preg_replace!

$source = str_replace("href=\"","href=\"parser.php?file=",$source);
