Can't get data from json - php

I need to get brand: "hello world"
When I send using post data with json and get it with
$input = Input::all();
then with
die(print_r($input));
this is written
Array ([[], {brand: "hello world"}, [], 1427154586016])1
And
I tryed using json_encode and get with
die(print_r($encode));
this
{data: "{"brand":"Hello world"}", dc: "142715"}1
now if I do
$brand = $encode['data'] or $brand = $encode['brand']
I get an error.
How do I get Hello world to var $brand

It looks like you're using json_encode() when you should be using json_decode(). But like kamlesh pointed out, it appears that your original JSON data is not valid JSON to begin with, so this would not help you. This wiki article has an example of valid syntax.
Also, if you're using laravel, you can use the helper function dd(), which will die() and var_dump() automatically for you, saving you a bit of time.
Hopefully this solves your problem, but if not, read the docs for the Input. There should be something there to get you on the right track.

convert query String to json in php

I send a QueryString formatted text like bellow to a php Script via Ajax:
title=hello&custLength=200&custWidth=300
And I want to convert this text to a JSON Object by this result in PHP:
{
"title" : "hello",
"custLength" : 200,
"custWidth" : 300
}
How can i do that. Does anyone have a solution?
Edit :
In fact i have three element in a form by title , custLength and custWidth names and i tried to send these elements via serialize() jquery method as one parameter to PHP script.
this code is for Send data to php:
customizingOptions = $('#title,#custLength,#custWidth').serialize();
$.post('cardOperations',{action:'add','p_id':p_id,'quantity':quantity,'customizingOptions':customizingOptions},function(data){
if (data.success){
goBackBtn('show');
updateTopCard('new');
}
},'json');
in PHP script i used json_encode() for convert only customizingOptions parameter to a json.
But the result was not what I expected and result was a simple Text like this:
"title=hello&custLength=200&custWidth=300"
I realize this is old, but I've found the most concise and effective solution to be the following (assuming you can't just encode the $_GET global):
parse_str('title=hello&custLength=200&custWidth=300', $parsed);
echo json_encode($parsed);
Should work for any PHP version >= 5.2.0 (when json_encode() was introduced).
$check = "title=hello&custLength=200&custWidth=300";
$keywords = preg_split("/[\s,=,&]+/", $check);
$arr=array();
for($i=0;$i<sizeof($keywords);$i++)
{
$arr[$keywords[$i]] = $keywords[++$i];
}
$obj =(object)$arr;
echo json_encode($obj);
Try This code You Get Your Desired Result
The easiest way how to achiev JSON object from $_GET string is really simple:
json_encode($_GET)
this will produce the following json output:
{"title":"hello","custLength":"200","custWidth":"300"}
Or you can use some parse function as first (for example - save all variables into array) and then you can send the parsed output into json_encode() function.
Without specifying detailed requirements, there are many solutions.

Extracting value from JSON data in PHP

I have extracted data from another website which is in JSON format - here is what I extracted: http://sub7legends.net/crawler.php
I need to get the value of kills and deaths from this.
I tried json_decode() in php of this data but when I var_dump() the result it just says "NULL".
What can I do to extract the required data?
The link doesn't work for me. But if you have a normal json just like this one:
{"kills": "5", "deaths": "3"}
Then the json_decode() method should work.
Here would be a sample code snippet:
$json_you_got_from_the_server = '{"kills": "5", "deaths": "3"}';
$result = json_decode($json_you_got_from_the_server);
$kills = $result->kills;
$deaths = $result->deaths;
echo "You have ".$kills." kills and ".$deaths." deaths.";
I haven't tried it, but it should work. If it doesn't, then please comment and I will try something else.
the current json contents are not valid, try validating it first. NULL is returned if the json cannot be decoded or if the encoded data is deeper than the recursion limit.
That json in the link you have pasted has no proper ending scroll to the end and you will see. If this is the same thing that you wanted to parse then it will always return null.

Simple JSON request in PHP

I have the following json
country_code({"latitude":"45.9390","longitude":"24.9811","zoom":6,"address":{"city":"-","country":"Romania","country_code":"RO","region":"-"}})
and i want just the country_code, how do i parse it?
I have this code
<?php
$json = "http://api.wipmania.com/jsonp?callback=jsonpCallback";
$jsonfile = file_get_contents($json);
var_dump(json_decode($jsonfile));
?>
and it returns NULL, why?
Thanks.
<?php
$jsonurl = "http://api.wipmania.com/json";
$json = file_get_contents($jsonurl);
var_dump(json_decode($json));
?>
You just need json not jsonp.
You can also try using json_decode($json, true) if you want to return the array.
you're requesting jsonp with http://api.wipmania.com/jsonp?callback=jsonpCallback, which returns a function containing JSON like:
jsonpCallback({"latitude":"44.9718","longitude":"-113.3405","zoom":3,"address":{"city":"-","country":"United States","country_code":"US","region":"-"}})
and not JSON itself. change your URL to http://api.wipmania.com/json to return pure JSON like:
{"latitude":"44.9718","longitude":"-113.3405","zoom":3,"address":{"city":"-","country":"United States","country_code":"US","region":"-"}}
notice the second chunk of code doesn't wrap the json in the jsonpCallback() function.
The website doesn't return pure JSON, but wrapped JSON. This is meant to be included as a script and will call a callback function. If you want to use it, you first need to remove the function call (the part until the first paranthesis and the paranthesis at the end).
If your server implements JSONP, it will assume the callback parameter to be a JSONP signal and the result will be similar to a JavaScript function, like
jsonpCallback("{yada: 'yada yada'}")
And then, json_decode won't be able to parse jsonpCallback("{yada: 'yada yada'}") as a valid JSON string
If country_code( along with closing parenthesis are include in your json, remove them.
This is not a valid json syntax: json
You are being returned JSONP, not JSON. JSONP is for cross-domain-requests in JavaScript. You don't need to use it when using PHP because you aren't affected by cross-domain-policies.
Since you are getting a string from the file_get_contents() function you can do a replacement of the country_code( text (this is the JSONP specific part of the response):
<?php
$json = "http://api.wipmania.com/jsonp?callback=jsonpCallback";
$jsonfile = substr(file_get_contents($json)), 13, -1);
var_dump(json_decode($jsonfile));
?>
Note
This works but JKirchartz's solution looks better, just request the correct data rather than messing around with the incorrect data.
Obviously in this situation, using the correct URL to access the API will return pure jSON.
"http://api.wipmania.com/json"
A lot of people are providing an alternative to the API in use, rather than answering the OP's question, so here is a solution for those looking for a way of handling jSONp in PHP.
First, the API allows you to specify a callback method, so you can either use Jasper's method of getting the jSON sub string, or you can give a callback method of json_decode, and modify the result to use with a call to eval. This is my alternative to Jasper's code example since I don't like to be a copy cat:
$json = "http://api.wipmania.com/jsonp?callback=json_decode";
$jsonfile eval(str_replace("(", "('", str_replace(")", "')", file_get_contents($json)))));
var_dump($jsonfile);
Admittedly this seems a little longer, more insecure, and not as clear to read as Jasper's code:
$json = "http://api.wipmania.com/jsonp?callback=jsonpCallback";
$jsonfile = substr(file_get_contents($json)), 13, -1);
var_dump(json_decode($jsonfile));
Then the jSON "address":{"city":"-","country":"Romania","country_code":"RO","region":"-"} tells us to access the country_code like so:
$jsonfile->{'address'}->{'country_code'};

JSON from Javascript not decoding in PHP

I've been going bananas trying to get some data from Javascript on one page to post to a php file asynchronously. I'm not even attempting to do anything with the data, just a var_dump to spit back out from the ajax call. NULL over and over again.
I've checked the JSON with JSONLint and it validates just fine. I'm getting my JSON from JSON.stringify - Firebug tells me I'm getting the following:
{"items":[["sa1074","1060"],["sa1075","1061"]]}
I've tried php://input, as well as json_decode_nice from the PHP manual comments about the function, and I've tried using utf8_encode - is there something wrong with my JSON?
EDIT: Derpity dee probably should have planned this post a bit more haha. Here's my PHP (using a suggestion from PHP manual comments)
function json_decode_nice($json, $assoc = FALSE){
$json = str_replace(array("\n","\r"),"",$json);
$json = preg_replace('/([{,])(\s*)([^"]+?)\s*:/','$1"$3":',$json);
return json_decode($json,$assoc);
}
if (isset($_POST['build'])){
$kit = file_get_contents('php://input');
var_dump(json_decode_nice($kit));
}
And the JS used to create it:
var jsonKit = JSON.stringify(kit);
$.post("kits.php?", {"build" : jsonKit},
function(data) {
$("#kitItems").html(data);
});
Also: Our host is on PHP 5.2 - I found this out when I uploaded a perfectly good redbean class only to have it explode. Had to re-implement with legacy redbean. Our host is busted.
SOLVED: Thanks to all who commented. Didn't think to check $_POST to see what was coming in. Quotes were being escaped with slashes in the $_POST and json_decode was choking on it. Adding this line before decoding solved the problem. Also forgot to set true to return an associative array. Thanks!
$kit = str_replace('\\', '', $kit);
Without seeing code - I'm just guessing here ... are you using a true assoc variable in your json_decode()?
<?php json_decode($jsonString, true); ?>
That had me stumped on a decode for quite some time my first time trying to decode something,

Need help Decoding JSON with XML

I have a set of data that looks like this when using print_r($var):
cbfunc({"query":{"count":"12","created":"2010-06-11T01:20:19Z","lang":"en-US"},"results":["\n 238.l.739089.t.4<\/team_key>\n 4<\/team_id>\n CHEE-HOO!!!<\/name>"]});
It looks like JSON to me, so I've tried to use json_decode but can't get it right. My goal is to print the xml data found in "results".
Any helpful pointers would be greatly appreciated.
It looks like it is wrapped in a callback cbfunc. so you need to strip that out before you can run json_decode on it.
try
$decode_this = substr($var, 6, -1);
You don't show the end of the responseText but the snippet above should give you everything between the start of the callback 'cbfunc(' and the last char, exclusive. You may have to change it to -2 if there is also a ; etc.
Thanks to ZZ Coder's response, I figured out the solution.
According to a comment on the json function at PHP. The JSONP needs to be converted to JSON (without padding) via a handy preg_replace...
$var=preg_replace('/.+?({.+}).+/','$1',$var);
Then, the JSON can be parsed to print the results data:
$obj = json_decode($var, true);
print $obj["results"][0];
