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:

Using window.location.hash (used to pass in ID for page) returns something like the following:
Also, for people asking why I used window.location.hash instead of window.location.href is because window.location.href started looping infinitely for some reason, and .hash does not. I don't think this should be a big deal, but let me know if it is and if I need to change it.

[The string of numbers is actually epoch system time]
When using PHP to try to retrieve this variable It is not picking up any text in the file It's supposed to write to.
<?php
$myfile = fopen("File1.txt","w");
echo $_GET['name'];
fwrite($myfile, $_GET['name']);
fclose($myfile);
?>
Try to print $_SERVER variable and it will give you the array and in the desired key you can get the values. It can help you to find that variable in the string.
If you want to get the value after the hash mark or anchor, that isn't possible with "standard" HTTP as this value is never sent to the server. However, you could parse a URL into bits, including the fragment part, using parse_url().
This should do the trick:
<?php
$name_query = parse_url("http://website.com/NewPage.php#?name=1418019307305");
$get_name = substr($name_query['query'], strpos($name_query['query'], "=") + 1);
echo $get_name;
?>
Working example: http://codepad.org/8sHYUuCS
Then you can use $get_name to store "name" value in a text file.
The hash tag is a fragment that never gets processed by the server, but rather the user-agent, i.e. the browser, so JavaScript may certainly access it. (See https://www.rfc-editor.org/rfc/rfc3986#section-3.5). PHP does allow you to manipulate a url that contains a hash tag with parse_url(). Here's another way to get the info:
<?php
$parts = parse_url("http://website.com/NewPage.php#?name=1418019307305");
list(,$value) = explode("=",$parts['fragment']);
echo $value; // 1418019307305
The placement of the hash tag in this case wipes out the query string so $_SERVER['QUERY_STRING'] will display an empty string. If one were to rewrite the url following best practice, the query string would precede the hash tag and any info following that mark. In which case the script for parsing such a url could be a variation of the preceding, as follows:
<?php
$bestPracticeURL = "http://website.com/NewPage.php?name=1418019307305#more_data";
$parts = parse_url( $bestPracticeURL );
list(,$value) = explode("=", $parts['query']);
$hashData = $parts['fragment'];
echo "Value: $value, plus extra: $hashData";
// Value: 1418019307305, plus extra: more_data
Note how in this case parse_url was able to capture the query string as well as the hash tag data. Of course, if the query string had more than one key and value, then you might need to explode on the '&' into an array and then explode each array element to extract the value.
Ho you all, I've got a script in a Wordpress post that sends the value of 4 variable to a URL.
The fact is that since natively WordPress converts & to &, the URL that is meant to recive those variable cannot get them, since the final URL will be
http://localhost/php/add.php?a=VALUE1&b=VALUE2&c=VALUE3&d=VALUE4
instead of http://localhost/php/add.php?a=VALUE1&b=VALUE2&c=VALUE3&d=VALUE4
Now I know that it is possible to fix this problem by commenting to lines in wp-includes/formatting.php, but I'm looking for a PHP function that can convert the URL with '&' to an URL with just '&'.
Is it possible? Thanks!
You will need to use htmlspecialchars_decode(). Consider this example:
$url = 'http://localhost/php/add.php?a=VALUE1&b=VALUE2&c=VALUE3&d=VALUE4';
$url = htmlspecialchars_decode($url);
echo $url;
// http://localhost/php/add.php?a=VALUE1&b=VALUE2&c=VALUE3&d=VALUE4
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 )
Could some one please help me out on this I have the following json string
string(1223) "YAHOO.Finance.SymbolSuggest.ssCallback({"ResultSet":{"Query":"google","Result":[{"symbol":"GOOG","name": "Google Inc.","exch": "NMS","type": "S","exchDisp":"NASDAQ","typeDisp":"Equity"},{"symbol":"GOOG.MX","name": "GOOGLE-A","exch": "MEX","type": "S","exchDisp":"Mexico","typeDisp":"Equity"},{"symbol":"GGQ1.F","name": "GOOGLE-A","exch": "FRA","type": "S","exchDisp":"Frankfurt","typeDisp":"Equity"}]}})"
But I cannot seem to get anywhere with it. Basically I want to just loop out the the results which are
[{"symbol":"GOOG","name": "Google Inc.","exch": "NMS","type": "S","exchDisp":"NASDAQ","typeDisp":"Equity"},{"symbol":"GOOG.MX","name": "GOOGLE-A","exch": "MEX","type": "S","exchDisp":"Mexico","typeDisp":"Equity"},{"symbol":"GGQ1.F","name": "GOOGLE-A","exch": "FRA","type": "S","exchDisp":"Frankfurt","typeDisp":"Equity"}]
Sorry my question is how can I loop or even print the first result for example
{"symbol":"GOOG","name": "Google Inc.","exch": "NMS","type": "S","exchDisp":"NASDAQ","typeDisp":"Equity"}
Your string is not JSON, it is JSON-in-Script. Notice the fragment that says:
YAHOO.Finance.SymbolSuggest.ssCallback(...)
When a browser receives the above mentioned script (actually a javascript code) it will call the YAHOO.Finance.SymbolSuggest.ssCallback function, passing the JSON data as the argument.
You did not mention if you want to access the JASON data on the server side or client? It its server side (PHP) then you can use regular expressions or string replacement functions to extract the portion you like. The you can use json_decode() function to convert the resulting string into an associative array.
Edit ----
A quick and dirty hack for converting JSONP to JSON:
<?php
$text = 'YAHOO.Finance.SymbolSuggest.ssCallback({"ResultSet":{"Query":"google","Result":[{"symbol":"GOOG","name": "Google Inc.","exch": "NMS","type": "S","exchDisp":"NASDAQ","typeDisp":"Equity"},{"symbol":"GOOG.MX","name": "GOOGLE-A","exch": "MEX","type": "S","exchDisp":"Mexico","typeDisp":"Equity"},{"symbol":"GGQ1.F","name": "GOOGLE-A","exch": "FRA","type": "S","exchDisp":"Frankfurt","typeDisp":"Equity"}]}})';
# //CONVERT JSONP to JSON\\
$text = preg_replace('/.+?({.+}).+/', '$1', $text);
# \\CONVERT JSONP to JSON//
$data = json_decode($text);
var_dump($data);
var_dump($data->ResultSet->Result[0]);
var_dump($data->ResultSet->Result[0]->symbol);
var_dump($data->ResultSet->Result[0]->name);
# etc etc
?>
Your result is not just a JSON string, it's a JSON string prepended by a call to a JSON function. This is quite certainly a JSONP call.
You must write the YAHOO.Finance.SymbolSuggest.ssCallback(data) javascript function and get the Json there. Check the JSONP query, you should be able to alter the name of this backreference function if you want another name, it's usually on of the parameter in the GET query.
Now you are maybe calling it directly from PHP and you are not in js envirronment. so you must write something in your PHP code to remove the YAHOO.Finance.SymbolSuggest.ssCallback( part and the ) at the end before parsing it as JSON data..
I'm sending a php script multiple urls (about 15) at once, all containing about 5 url variables. In my script, I'm parsing the chunk of urls into individual ones by splitting them with two backslashes (which i add upon before to the script), and then curling each individual url. However, when I run my script, it only accepts a url up to the "&" symbol. I'd like to have the entire chunk, so that I can split it up later in my script. What might be the best way to approach this issue?
Thanks.
An example of what happens when i send my script a url chunk:
<?php
/*
$url variable being sent to script:
http://www.test1.com?q1=a&q2=b&q3=c&q4=d\\http://www.test2.com?r1=a&r2=b&r3=c&r4=d\\http://www.test3.com?q1=a&q2=b&q3=c&q4=d\\http://www.test4.com?e1=a&e2=b&e3=c&e4=d
*/
$url = $_GET['url'];
echo $url; // returns http://www.test1.com?q1=a
//later on in my script, i just need to curl each "\\" seperated url
?>
You need to urlencode() the (data) URLs before appending them to your script's request.
Otherwise, PHP is going to to see ?listOfUrls=http://someurl.com/?someVar=SomeVal& and stop right there, due to the literal "&"
If you're building the query string in PHP you could try something like:
<?PHP
//imagine $urls is an array of urls
$qs = '?urls=';
foreach($urls as $u){
$q .= urlencode($u) .'\\';
}
I also suspect you can play with [] notation in the url so that on the other side of the GET, you get a nice clean array of URLs back, instead of having to parse on some delimiter like "\"
Since you didn't url encode your url param, everything after the first & is treated as the param to the original url.
The $_GET array is formed by splitting on ampersands. URL-encode the URLs before passing them as parameters. PHP should decode them for you.
Example: pass url=http://www.test1.com?q1=a%26q2=b%26q3=c%26q4=d\\http://www.test2.com?r1=a%26r2=b%26r3=c%26r4=d\\http://www.test3.com?q1=a%26q2=b%26q3=c%26q4=d\\http://www.test4.com?e1=a%26e2=b%26e3=c%26e4=d
You can do away with the '\\' by turning the parameter into an array. Example: use url[]=http://www.test1.com?q1=a%26q2=b%26q3=c%26q4=d&url[]=http://www.test2.com?r1=a%26r2=b%26r3=c%26r4=d&url[]=http://www.test3.com?q1=a%26q2=b%26q3=c%26q4=d&url[]=http://www.test4.com?e1=a%26e2=b%26e3=c%26e4=d
