is it possible to use preg_replace to change the text in an included file?
file to be included has this text:
I want to replace all instances of 'a href="/' with 'a href="http://myserver.com/' in the included file so when the file is included, it will have the following
Is that possible?

You could set up a variable just before the include to specify the path or to pull it from a url or form.
$location = "http://www.myserver.com/"
then in the include file set it to

or if you needed to use preg_replace, you could do so like this...
$domain = "http://www.mysite.com";
preg_replace("/\\<a\\s(.*)href=\\"(.*)\\"/is", "<a $1href=\\"".$domain."$2\\"", $contents);
where $contents is the code to apply the relplace... I think that should work anyway... If its anythin like usual, mordred will come along with some amazing regex :D

There's probably a simple solution to this problem, provided you actually display the file contents in a browser. So no amazing regex from me right now, must save energy. :D
$domain = 'http://www.mysite.com';
$contents = str_replace('</head>', "<base href=\"$domain\"></head>", $contents);
Just utilizing the power of HTML 3.2 and putting a <base> address into the header part should force all browsers to resolve all links from the $domain address. If that does work for you, it would also solve the problem of distinguishing between absolute/relative links in various attributes (href, src,). Give it a try.

There is something about me... I can never give the simplest solution... ah well.. nice 1 mordred.

Actually, I think you're assuming I have access to modify the included file, which I do not.
The included file is actually a .cgi file for a search script on another server in our intranet. The problem is that when the search results are displayed, all the links are relative.
To better explain the problem, I've got a file on my server named search.php
The contents are basically this...
$term = urlencode($_POST['keyword']);
$file = "http://otherserver.com/cgi-bin/search.cgi?keyword=".$term;
The search.cgi file actually returns a complete html file, so I also need to dump the <html> -> <head> junk as well. I was trying to get something like this to go, but it doesn't seem to work.
$content = include($file);
preg_replace("/\<a\s(.*)href=\"(.*)\"/is", "<a $1href=\"".$domain."$2\"", $content);

im assuming that you mean that the cgi file returns a page with <html></html>...
what you have done there will not work (as far as i know), because include puts the entire file and adds it to the page...
you could try:
$cont = ob_get_contents();
but i dont know if that would work...

That would work, missing-score. It's also a common idiom to capture the output of an included file via ob_get_contents(), and it allows bcarl to execute the regex solutions we posted on the captured output.

cool. ive used output buffers before, just didnt know how included files worked within that. thanks.
