Re: Afterburner's comment on passing URLs via GET parameters.
Your regex method is neither sufficient or necessary. There are characters other than & which
will cause problems, and using a full-blown regex is rather heavyweight.
This is what the functions urlencode() and rawurlencode() are for. Before incorporating your
parameter-URL into a link, call urlencode() on it. urldecode() will then transform this string back
into the original URL, *BUT* you don't normally have to call this as PHP will automatically
urldecode() incoming GET parameters for you (you only need call it explicitly if you're using
this encoding to pass the URL through some other medium, such as a data file of your own format.)
Eg.
$myurl = "http://somewhere/script1.php?param1=val1¶m2=val2";
printf("<a href=\"http://somewhere/script2.php?url=%s\">Clicky</a>",
urlencode($myurl));
[in script2.php:]
$myurl = $_REQUEST['url']; # already decoded
You should then be able to pass $myurl directly to file() or any other URL enabled function.
