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'.
What's wrong?
I want to get whole URL string. Including &,?,or everything else.
You need to use encodeURIComponent to encode the url parameter.
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

I need to pass a url using a GET address. To give an example which was I have tried:
http://www.example.com/area/#http://www.example.com/area2/
I've also tried replacing the forward slashes with other characters but that doesn't seem to work. How would you pass a url in a GET?
As I have understood, you should use url_encode() and url_decode().
The function url_encode() lets you create a string that can be used as a link.
You should use it this way:
$link = 'goto.php?link=' . url_encode($_POST['target_site']);
And when you were going to redirect to the user defined site (eg), you can decode the parameter given this way:
$decoded_link = url_decode($_GET['link']);
// Now it's safe to use the given URL (for example I can redirect to there)
header('location: ' . $decoded_link);
Hope it helps.
The # character links to an anchor on the page. The browser will automatically scroll to the element with the id after the point sign. So that's not what you're looking for.
To pass a GET parameter, the syntax would be like this:
http://example.com/area?http://example.com/area2
Then, if you var_dump($_GET), you'll see your URL. But, if you have other fields you also want to pass in your URL, you can use key=value pairs, like so:
http://example.com/area?url=http://example.com/area2¶m1=a¶m2=b
In this case, your URL will be available in $_GET['url'].
There is a string XX&YY and I'm passing it to another page. ie, localhost/sample/XX&YY/1 for some processing. Now when I try getting the name value on the other side I'm able to get only XX and not full XX&YY. How to rectify it? Any ideas?
Note : here is my url localhost/sample.php?name=somevalue&pageno=somevalue has been url re-written to localhost/sample/name/pageno.
You have to escape the URL . You can use rawurlencode() or urlencode() to encode your URL.
sidenote: Difference of the 2 functions
If I'm understanding correctly, this is the URL to your script:
http://localhost/sample/name/pageno
Which is then rewritten by your web server to this:
http://localhost/sample.php?name=somevalue&pageno=somevalue
Then, this is how you should format the URL:
$url = sprintf('http://localhost/sample/%s/%s',
urlencode('XX&YY'),
urlencode('1')
);
I have a download page that take arguments like the download URL, the download-counter data file url, and the page to return to after downloading.
It is arranged like so:
start.php?url=...&page=...&file=...
(Download url, redirect page, counter file)
The problem is, when the redirect page contains PHP arguments with ? and & symbols, the URL becomes a confusing mess for PHP to work with.
Example:
start.php?url=URLTEXT&page=page?test1=x&test2=xx&file=FILETEXT
What should happen:
url=URLTEXT
page=page?test1=x&test2=xx
file=FILETEXT
what happens:
url=URLTEXT
page=page?test1=x
test2=xx
file=FILETEXT
How could I substitute characters or somehow make these arguments pass correctly in php?
Thanks for any help you can give.
Well, I'm not sure how your "messed up" URL looks like. However the string after the "?" is called Query String, and you can decode/encode it with
urlencode($normalString); //will be encoded for use in URL
urldeocde($queryString); //will be decoded for "normal" use
EDIT:
Here is some short example:
echo "Encode for use in URL: ";
echo urlencode("this is a string & üäöllasdlk<bbb2");
echo "<br />";
echo "Decode to use it in your script: ";
echo urldecode($_SERVER['QUERY_STRING']);
Output:
Encode for use in URL:
this+is+a+string+%26+%C3%BC%C3%A4%C3%B6llasdlk%3Cbbb2
Decode to use it in your script: test=12
(Assuming you have a Querystring containing the variable test=12)
Just use htmlspecialchars function on your URL string:
http://php.net/manual/en/function.htmlspecialchars.php
I have been using URL decode on encoded URL variables from $_get.
The current problem I am facing is I have a URL encoded like this:
blah.php?url=http%3A%2F%2Fm.youtube.com%2F#/watch?feature=player_embedded&v=zd7c5tQCs1I&desktop_uri=%2Fwatch%3Fv%3Dzd7c5tQCs1I%26feature%3Dplayer_embedded
I'm not sure what kind of encoding this is, can someone help me? When I use just "urldecode" on this it just returns m.youtube.com
Edit: My problem is not that url decode isn't working, it works if I manually enter this encoded URL and use urldecode(), but when this encoded url is in the actual pages url and I use the _GET function then I try to decode it it stripes off everything after the "#" in the URL.
<?php print urldecode($_GET["url"]);?>
It returns
"http://m.youtube.com/"
instead of
"http://m.youtube.com/#/watch?feature=player_embedded&v=zd7c5tQCs1I&desktop_uri=/watch?v=zd7c5tQCs1I&feature=player_embedded"
I think the issue is that the pound sign is not encoded, if I refresh the page it strips away the pound sing and everything after it, so how do I get around this? Can I still retrieve the info from "GET" even though there is a pound sign? (#)
The problem is that the full link has multiple = signs, and browser cant determine, that the other = signs refer just to the url= parameter.
in your case, at first, you need to use function before link is given to url= parameter:
========================= 1) JAVASCRIPT ======================
<script type="text/javascript">
var mylink = encodeURIComponent('http://testest.com/link.php?name=sta&car=saab');
document.write("http://yoursite.com/url=" + mylink);
</script>
========================= 2)or PHP ===========================
<?php
$mylink = 'http://testest.com/link.php?name=sta&car=saab';
echo 'http://yoursite.com/url='.urlencode($mylink);
?>
so, your output (url parameter) will get like this
http://yoursite.com/url=http%3A%2F%2Ftest.com%2Flink.php%3Fname%3Dsta%
so, the url parameter will get the encoded url.
after that, your .php file needs to decode that "url" parameter-
<?php
$varr = $_GET['url'];
$varr = preg_replace("/%u([0-9a-f]{3,4})/i","&#x\\1;",urldecode($varr));
$varr = html_entity_decode($varr,null,'UTF-8');
echo $varr;
?>
that will give you the correct value
I read on php.net about urldecode function and they say that superglobal $_get is already decoded, ex: "The superglobals $_GET and $_REQUEST are already decoded. Using urldecode() on an element in $_GET or $_REQUEST could have unexpected and dangerous results."
It is encoded into ASCII format .
see http://www.w3schools.com/tags/ref_urlencode.asp
So here is the problem, the pound sign (#) (Hash) wasn't encoded... since I can't go back and re-encode it I have to use javascript (ex. alert(window.location.hash);) to send me the full URL after the hash then I append it to PHP's version of the URL, I THEN use a find and replace function in PHP to replace the "#" with "%23", then I use the urldecode method and it returns the full proper url decoded.
This encoding is called percent encoding or URL encoding. You can use urldecode for decoding it. (Example: http://phpfiddle.org/lite/code/0nj-198 )
I think I have the need to take a uri which has been decoded in PHP, and re-encode it.
Here is the situation:
JavaScript passes encoded uri as query string parameter to php script.
PHP script embeds uri as a hidden input value in an html document, responds with the document to a user agent.
JavaScript reads embedded uri and sets location of current document based on value of hidden input.
On Step 2, I am finding that the Uri is fully decoded after reading it in via $_GET. So when I embed the uri in the hidden input, it becomes un-encoded. So I would like to run a PHP script which re-encodes the Uri properly ex:
http://my.example.com/dog walk?is=very great
==>
http://my.example.com/dog%20walk?is=very%20great
Is there a pre-built php function for this or should I just write my own?
PLEASE NOTE: urlencode and urldecode are not the answer to get the desired input/output I have in the example above.
Thanks,
Macy
Are you looking for : http://fr.php.net/manual/en/function.urlencode.php ?
I don't know if will help you, but PHP have 3 useful functions:
$url = parse_url('put the url here');
parse_str( $url['query'], $query ); // generating an array by reference (yes, kinda weird)
echo $query; //in this line, you can encode or decode.
or, if you want to mount a query, you can use http_build_query(); that accepts values from an array, like:
$url = 'http://my.example.com/dog walk?';
$array = Array (
'is' => 'very_great',
);
$url_created = $url . http_build_query($array);
urldecode:
