Ampersand in a Variable

[Ian Cunningham]

I have a file (test.php) which I call from the browser, for example:

test.php?url=http://www.example.com/abc.php?a=1&b=2

in the test.php file I have the code:

echo "$url";

But, I only see "http://www.example.com/abc.php?a=1" printed, and everything after the ampersand is missed out. How would I use URLEncode to get past this (if that is what is needed)?

I bet if you do an echo $b you would get a value of 2. The problem is that PHP thinks you are defining 2 variables - url & b. I don't know how to fix it other than echo $url.$b or rebuilding the variable $url=$url.$b .

how about something like:
$_ENV['QUERY_STRING']

"test.php?url=" . urlencode("http://www.example.com/abc.php?a=1&b=2")

-> $_GET['url']

test.php?url=urlencode("http://www.example.com/abc.php?a=1&b=2

-> substr($_SERVER['QUERY_STRING'], 4)

urlencode() your variables before tacking them on your querystring. You shouldn't put more than one "?" in your URL, it's bad form. Encoding the querystring variables will change your "?" and "&" characters into non-threatening strings that will remain intact until you "GET" them back.

You need the & to be coded as & in order for the page to be valid as an HTML document anyway.
