Generate JavaScript friendly string using PHP

[Stickbread]

After I download the page, I use PHP's addslashes method to every line, and then I just wrap every line in a document.write. Here is the script (script.php):

$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);
     $str = "document.write(\"$line\");\n";
     print($str);
}

Then to display a webpage, I use:
<script language="JavaScript" src="script.php?url=http://www.google.com"></script>

However, this is not working on all web pages. For example, it works for

http://www.google.com,

but not for

http://www.yahoo.com,

and 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 rather urgent.

i think this may be a new line issue. another post of yesterday addressed it.

i recall that the solution was to replace the "\r" and "\n" characters with a blank. this may, of course, have a detrimental effect on the formatting.

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