The " inside the javascript will be eaten by the shell because they're not escaped. It doesn't know the quotes are supposed to be for javascript, and handles them itself.

Code:

$ echo " window.status = "Redirecting..." + myvar;"
 window.status = Redirecting... + myvar;

$ echo " window.status = \"Redirecting...\" + myvar;"
 window.status = "Redirecting..." + myvar;

$

...but it'll be more efficient and far less typo-prone to do this in a here-document, that will let you plunk it down nearly verbatim:

Code:

cat <<EOF
<script type="text/javascript">"
function exec_refresh()
{
window.status = "Redirecting..." + myvar;
myvar = myvar + " .";"
var timerID = setTimeout("exec_refresh();", 100);
if (timeout > 0)
{
timeout -= 1;
}
else
{
clearTimeout(timerID);
window.status = "";
window.location = "Test.com Web Based Testing and Certification Software v2.0";
}
}
var myvar = "";
var timeout = 20;
exec_refresh();
</script>
EOF

${VARIABLES} and `backticks` will still be substituted inside a here document. Escape ` and $ with \ to avoid it.

Note the ending EOF must be at the beginning of the line, not indented!

LEARN ABOUT PHP

http_redirect

HTTP_REDIRECT(3)							 1							  HTTP_REDIRECT(3)

http_redirect - Issue HTTP redirect

SYNOPSIS

       bool http_redirect ([string  $url], [array  $params], [bool  $session = false], [int  $status])

DESCRIPTION

	Redirect to the given url.

	The  supplied $url will be expanded with http_build_url(3), the $params array will be treated with http_build_str(3) and the session iden-
       tification will be appended if $session is true. The HTTP response code will be set according to $status. You can use one of  the  redirect
       constants for convenience. Please see RFC 2616 for which redirect response code to use in which situation. By default PHP will decide which
       response status fits best.

	To be RFC compliant, "Redirecting to <a>URL</a>." will be displayed, if the client doesn't redirect immediately, and  the  request  method
       was another one than HEAD.

	A log entry will be written to the redirect log, if the INI settinghttp.log.redirect is set and the redirect attempt was successful.

PARAMETERS

	      o $url
		- the URL to redirect to

	      o $params
		- associative array of query parameters

	      o $session
		- whether to append session information

	      o $status
		- custom response status code

RETURN VALUES

	Returns FALSE or exits on success with the specified redirection status code. See the INI settinghttp.force_exit for what "exits" means.

EXAMPLES

       Example #1

	      A http_redirect(3) example

	      <?php
	      http_redirect("relpath", array("name" => "value"), true, HTTP_REDIRECT_PERM);
	      ?>

	      The above example will output:

	      HTTP/1.1 301 Moved Permanently
	      X-Powered-By: PHP/5.2.2
	      Content-Type: text/html
	      Location: http://www.example.com/curdir/relpath?name=value&PHPSESSID=abc

	      Redirecting to <a href="http://www.example.com/curdir/relpath?name=value&PHPSESSID=abc">http://www.example.com/curdir/relpath?name=value&PHPSESSID=abc</a>.
