I want to get only URL string in parameter.
So I coded below :

//In my HTML file.
<script>
document.write('<iframe id="ifr1" 
src="http://{domain}/prj.php?url=https://www.google.co.kr/search?sugexp=chrome,mod=3&sourceid=chrome&ie=UTF-8&q=url+utf8+encoding#sclient=psy-ab&hl=ko&newwindow=1&prmdo=1&tbm=klg&q=google&oq=google&aq=f&aqi=g10&aql=&gs_l=serp.3..0l10.2207859.2208404.3.2208459.6.4.0.1.1.3.496.1353.2-2j1j1.4.0...0.0.O1lbexylHQM&pbx=1&prmdo=1&bav=on.2,or.r_gc.r_pw.,cf.osb&fp=b8fee9fdb4e7f90&biw=1440&bih=828&a=' +'asdf'+" width="100%" height="100%" frameborder="0">   </iframe>');
</script>

//In my php file
$message = $_GET['url'];
echo("$message");

But I only get ‘https://www.google.co.kr/search?sugexp=chrome,mod=3&#8217;.

What’s wrong?

I want to get whole URL string. Including &,?,or everything else.

    The reason is that you use an encoding into another encoding.

    The first is:

    prj.php?url=[somedata]

    where [somedata] is an URL with another key/value collection:

    https://url/etc/search?key1=value1&key2=value2

    If the url parameter is not urlencoded there is no way to distinguish the parameters of /prj.php from the parameters of /search, it is assumed that all the parameters defined with &key=value&key=value... syntax belong all to the first page.

    The trick is to url-encode the url parameter, but how you do it depends on the context.

    If the url is dinamically generated via PHP, use the urlencode() function.

    If your url is hard-coded (not generated via PHP), you can write for yourself a little PHP tool to do the job, or use an online encoder like http://www.opinionatedgeek.com/dotnet/tools/urlencode/Encode.aspx
