Create javascript friendly string from PHP

I've recently written a PHP script that downloads a webpage, and then creates the javascript code to display that webpage.

That way, I can do something like this:

So it downloads the page, and then wraps each line in [url removed, login to view]().

Here is the script:

$url = $_GET["url"];

$file = file("$url");

for($i = 0; $i < count($file); $i++)


$line = $file[$i];

$line = substr($line, 0, strlen($line)-1); // removes the new line character

$line = addslashes($line);

$str = "[url removed, login to view](\"$line\");\n";



The problem is that it doesn't work on every web page... For example, it works with [url removed, login to view], but not [url removed, login to view], or most others.

My guess is that PHPs addslashes does not escape the proper characters to generate a javascript friendly string.

Could somebody help me get this script working? It's very urgent, and I'll need it finished within an hour or two of the project acceptance.

I actually solved my problem early last night, before the project was approved. I think the problem was on that line where I stripped off the newline character. I changed it so that I now just strip off all \r and \n, and it seems to work well. Then, I had to output a line giving it a new base href, so that the images with relative paths would work...

Now the only problem is that google adsense ads, and several other third party scripts are not downloading.... I thought that it might be because I myself was acting as a third party, because I was downloading the remote page and displaying it... but then I realized that all google adsense ads are served to a third party, so that wasn't the problem. To double check, I checked my logs and googles '[url removed, login to view]' actually was being downloaded, it just wasn't being displayed properly.

I know that javascript c an be used to display and render other javascript, because I've tested it with a simple hello world. Perhaps the problem is just that it can't create new variables, and googles script uses several variables...

Perhaps there is a solution using javascript's eval()?

Could you give an example as to how to do these things? I was thinking about both of those problems last night, and after some research it seemed like the solution was to use psocketopen, and then write a custom user-agent and referer header when requesting the file.

Here is the current version of the script ([url removed, login to view]). What I'm trying to do is get google adsense ads and other third party scripts to display correctly:

$url = $_GET["url"];

$lines = file($url);

for($i = 0; $i < count($lines); $i++)


$line = $lines[$i];

$line = str_replace("\n", "", $line);

$line = str_replace("\r", "", $line);

$line = addslashes($line);

print("[url removed, login to view](\"$str\");\n");

Alright, the original problem I was having was the line where I strip off the last character on the line. I changed it so that it just strips all \n and \r from the string, and that solved a lot of problems.

Then I noticed that any image that is using a relative path for it's source was not being displayed. That is because the images do not reside on my server. So to solve that problem, I added a line changing the document base, something l ike this:

No my problem seems to be when there is already javascript on the page I'm trying to 'embed'. It works fine with simple scripts, and I tested it with a simple hello world javascript. But the problems are with google adsense, and other remotely hosted scripts. I believe the problem is when the scripts need to create new variables. This is in short what I'm trying to do:

[url removed, login to view](" ");

And it's not working... I think that the solution may need to copy all embedded javascript code into it's own function in the 'higher level' script... so it would output something like this:

function doScript1


var temp = "hi";

[url removed, login to view](temp);


[url removed, login to view](" ");

I'm not sure if there is another solution, or if this would work. I'm willing to change the maximum bid if somebody thinks that they can come up with a solution.
