Url Decoding in PHP

URL Decoding in PHP

Your string is also UTF-8 encoded. This will work:

echo utf8_decode(urldecode("Ant%C3%B4nio+Carlos+Jobim"));

Output: "Antônio Carlos Jobim".

PHP URL decode GET

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.

How to encode URL in JS and Decode in PHP?

Try this in your javascript code

window.location.href = 'products.php?price_range='+encodeURIComponent('-INFto2000,2001to5000');

You can access the decoded value in $_GET['price_range']. $_GET variables are decoded by default in PHP.

Does PHP automatically do urldecode() on $_POST?

Yes, all the parameters you access via $_GET and $_POST are decoded.

The reason the urldecode() documentation doesn't mention $_POST is because the POST data might not be URL-encoded in the first place. It depends on whether the POST data is submitted in application/x-www-form-urlencoded format or multipart/form-data format.

But all this is transparent to the application.

The documentation of $_GET does mention this explicitly, though.

Note:

The GET variables are passed through urldecode().

How to properly URL encode a string in PHP?

For the URI query use urlencode/urldecode; for anything else use rawurlencode/rawurldecode.

The difference between urlencode and rawurlencode is that

• urlencode encodes according to application/x-www-form-urlencoded (space is encoded with +) while
• rawurlencode encodes according to the plain Percent-Encoding (space is encoded with %20).

What does the value of the cookie is automatically URLencoded when sending the cookie, and automatically decoded when received mean?

Http cookies are headers that are transferred between the client (the browser), and the webserver.

When you use setcookie, what you are doing is instructing the PHP interpreter to inject a header in its response with this format:

Set-Cookie:name=value

That cookie will be stored by the browser, and returned by it in future requests (to the same host) in the Cookies request header like this:

Cookie:name=value;cookie2=value;cookie3=value

Normally, when transferring this you should urlencode any special characters. Let's say that I wan to specify a cookie named "operator" with a value of ">", then I should emit this header:

Set-Cookie:operator=%3E

When it says that the value is automatically urlencoded, is saying that you don't have to worry about that. You can simply do:

setcookie('operator', ">");

And PHP will handle the urlencoding directly, producing the correct header.

On the server side, you'll receive cookies in the $_COOKIES superglobal, and in the same way that happens with $_GET and $_POST, values will be automatically urldecoded for you. So if the client returns the previously set cookie %3E, you'll see: > in your code.

If you use your browser inspector, you can see the relevant headers on any request-response. E.g.:

request (returning cookie)

response (setting cookie)

setrawcookie, does the same, but you have to urlencode on your own. From the docs:

setrawcookie() is exactly the same as setcookie() except that the cookie value will not be automatically urlencoded when sent to the browser.

More likely than not, you won't have any reason to ever use setrawcookie directly.

php URL decode get '+' from URL

Don't run urldecode, the data in $_REQUEST is automatically decoded for you.

A plus sign, in a URL, is an encoded space. PHP decodes the hex value to a + automatically. Then, by running the result through urldecode, you are manually (and incorrectly) decoding the + to a .

PHP url decode do not work

just use

if(!empty($_GET["pass"]))
{
    $pass= $_GET["pass"];
}

PHP - GET & POST Methods

http://www.test.com/index.htm?name1=value1&name2=value2

• The GET method produces a long string that appears in your server logs, in the browser's Location: box.
• The GET method is restricted to send upto 1024 characters only.
• Never use GET method if you have password or other sensitive information to be sent to the server.
• GET can't be used to send binary data, like images or word documents, to the server
• The data sent by GET method can be accessed using QUERY_STRING environment variable.
• The PHP provides $_GET associative array to access all the sent information using GET method.
