Loading a page from another site on my site

yellum

Hi,
I want to take content from a page on another site and display it on a page on a site I have control of. I also want to reformat this page to remove some stuff and add other stuff.

Any scripts out there that do that, or anyone want to offer snippets of code ?

Getting the page is a piece of widdle if allow_url_fopen is on, you can just use the url in any of the filesystem functions; for example:

[PHP]<?php
// file() reads each line of the 'file' into an array
// implode() with empty glue bungs 'em into a var
$file = implode('', file('http://www.linux.ie/'));
?>[/php]Reformatting and/or removing depends on what you want to do. You might need the regex functions, or the string functions might do. Give us an example...

Hmmm, that doesn't seem to work, unfortunately.

Its PHP Version 4.1.1 , its running in win2k, set up using phpTriad.

Most php scripts work though ....

Check to see if allow_url_fopen is on first anyway.

[PHP]
$varPost = $_POST;

if ($varPost != "") { include("$varPost"); }
else {echo "
<form name=\"form\" method=\"POST\" action=\"test.php\">
<input type=\"text\" name=\"url\">
<input type=\"submit\" name=\"Submit\" value=\"Submit\">
</form>"; }

Got a server error with your code Flame

Well, if the url_open wrappers are enabled, I don't know yellum. Possibly it's something to do with Windows, although I seem to remember being able to do it before. Long time since I did devel on Windows though.

I've been trying to do the same thing (basically a script that pulls the listings of whats on now from the Aertel page).


Everything I need is between an opening and closing tag (which are only used once in the page). The problem is my loop to get just whats between these tags.

Anyone got any suggestions?

Whut? If the target only appears once on the page, and the page is contained in a string, you don't need a loop.

Post some code please.

Just define a $start and $stop variable.

$start = "<tag you wish to start from>";
$stop = "<tag you wish to stop at>";

Then assuming that the web page is reachable (you should trap the fopen request) you can grab the entire of the page into a variable. (say we use $file in the fopen request)

$file = fopen($webpage, "r");

Youll then want to get contents of the webpage......

$contents = fread($file, <numofcharstoread>);

when thats done your gonna need to do a string search and grab just whats between your $start and $stop variables....

eregi("$start(.*)$stop", $contents, $grabbedtemp);

This uses eregi to do just that and store the results in the array $grabbedtemp.

Any changes you want to make to the html can be made now (changing relative url's to literals, putting in fancy bits etc etc can be done with simple str_replace/ereg_replace commands).

Then simply echo out $grabbedtemp[0]

Youll want to error check each step of course as network connections are not always available or the webpage may be down etc....

It should be noted that this is a colossal security hole. What if I submit '/etc/passwd', or write a PHP script to echo a PHP script, include it via 'http://mysite.com/evil_script.php', and bingo, I can delete your entire file structure, do a litte searching to find your DB details, erase your databases, and crash your server. I'm not that mean though
