Output when success
string(66)
"{"status":true,"message":"success","data":{"amountDue":"-504.20"}}"
Output when error
string(119) "{"status":false,"message":"An error occured while getting
full subscriber profile: Subscription not found MPP servers"}"
How should I write in php to get the amount due from the output? I am new to REST api. Can someone show me ? Thank you
That is a JSON-encoded response. Use json_decode() to convert the string back into an array, and then access the array element:
$output = '{"status":true,"message":"success","data":{"amountDue":"-504.20"}}';
$results = json_decode($output,true);
if($results["status"])
{
echo "Success! Data: " . print_r($results,true);
}
I assume that you can at least send proper request to the endpoint and you are able to capture the response.
You receive a json string which must be parses so if:
$response = '{"status":true,"message":"success","data":{"amountDue":"-504.20"}}';
$responseArray = json_decode($response, true);
Then you will get a responseArray as associated array (the second parameter) so you can get amount due like that
$amountDue = $responseArray['data']['amountDue'];
You could also parse json data into an StdClass which turn all fields in json into an object's property. To do that abandon the second parameter in json_decode function
$resultObj = json_decode($response);
$amountDue = $resultObj->data['amountDue'];
All depends on your requests.

I've been trying to fix this thing for an entire day already and couldn't get it to work. Something which is supposed to be easy.
The problem is, I do a GET request to this URL: http://api.champion.gg/stats?api_key=851a15d4f271849f3beee664ea03db3b
Then, I try to convert the result to a JSON format using the PHP function json_decode. I do it like this:
$httpResponse = drupal_http_request('http://api.champion.gg/stats?api_key=851a15d4f271849f3beee664ea03db3b');
$data = $httpResponse->data;
$datas = json_decode($data);
var_export($datas);
$error = json_last_error_msg();
echo "Error = $error";
And the error message returns "Control character error, possibly incorrectly encoded"
I have already tried using stripslashes, deleting BOM, html_entities, deleting some initial characters and none of them have worked.
You have to set "Accept-Encoding" header to "gzip, deflate", otherwise the response is truncated.
$httpResponse = drupal_http_request('http://api.champion.gg/stats?api_key=851a15d4f271849f3beee664ea03db3b', array('Accept-Encoding' => 'gzip, deflater'));
$data = gzdecode($httpResponse->data);
I have a problem with json parsing.
I have already read the many questions here on stackoverflow but I can't figured out what I'm missing.
In my site I use Facebook Api to post my feed using curl and it respond with a json message.
I take this response and I save it in my database.
In my Backoffice I need to retrieve this message and print it in case of error.
Here an example about an error message:
{"error":{"message":"(#1500) The url you supplied is invalid","type":"OAuthException","code":1500}}
In my php page I need to get just the message part so I did:
$message = get from the db and fetch;
$error_array = json_decode($message,true);
print_r($error_array);
but it doesn't print anything, just a blank page.
If I just print $message I can see the entire string.
What am I missing?
This issue it's driving me crazy all day long!!
I tried the following:
<pre>
<?php
$jsonStr = '{"error":{"message":"(#1500) The url you supplied is invalid","type":"OAuthException","code":1500}}';
$error_array = json_decode($jsonStr, true);
print_r($error_array);
?>
and getting output:
Array
(
[error] => Array
(
[message] => (#1500) The url you supplied is invalid
[type] => OAuthException
[code] => 1500
)
)
It's working as intended.
I suspect the problem is with this:
$message = get from the db and fetch;
After you load the $message variable, do a var_dump($message) and see if the string is in there (as expected).
$jsonString = '["m#gmail.com","b#gmail.com","c#gmail.com"]';
$arrayOfEmails=json_decode($jsonString);
Or
$jsonString = "[\"a#gmail.com\",\"b#gmail.com\",\"c#gmail.com\"]";
$arrayOfEmails=json_decode($jsonString);
// Set username and password
$ih_soap_user= $this->config->item('interUser');
$ih_soap_pass=$this->config->item('interPass');
//echo $ih_soap_user.':P:'.$ih_soap_pass;
// Set soap namespace
$ih_soap_ns = 'http://www.interhome.com/webservice';
// Create new instance of SoapClient with the interhome web service URL
$client = new
SoapClient($this->config->item('interSoap'),array('trace'=>'1'));
// Create new soap header and set username and password
$header = new SoapHeader($ih_soap_ns,
'ServiceAuthHeader',
array('Username' => $ih_soap_user,'Password' =>
$ih_soap_pass),
true
);

) );
try{
$result = $client->__soapCall("Search",array('parameters'=> $params),null,$header);
Hi guys..Any Idea why this call when I pass any not empty array, as for example ,as I made for 'HouseApartmentType', returns this error
A PHP Error was encountered
Severity: Notice Message:
Array to string conversion
Filename:
controllers/houses.php Line
Number: 269
And when it's only empty array or a string the soap call function is working... I need to pass array of options to one parameter....
LINE 269 is
$result = $client->__soapCall("Search",array('parameters'=> $params),null,$header);
This is probably solved already, but I also had problems with this and I thought I should post here when I finally found the solution. (The solution is not nusoap, it throws the same error.)
The error only seems to come from the soapCall call generation, it really is the Web Service that causes it. When you run __soapCall, it first asks the server which datatypes the parameters should have and then tries to comply. So if you try to feed an array when the service expects a string, it will do the array to string conversion when the request is generated.
i think you should look at the manual how a soapcall work:
$params = array(
'Page'=>$page,
'PageSize'=>'10',
'OrderDirection'=>'Ascending',//Descending
'OrderBy'=>'Price',//Favorite,Place
'LanguageCode'=>'EN',
'CurrencyCode'=>'EUR',
'CountryCode'=>trim($ajaxSearchCountryCode),
'RegionCode'=>trim($ajaxSearchRegionCode),
'PlaceCode'=>$ajaxSearchPlaceCode,
'CheckIn'=> $ajaxSearchCheckinDate,
'Duration'=>'7',
'ThemeFilter'=>$ajaxSearchTheme,
'HouseApartmentType'=>'House', // changed to string instead of array
'SpecialOffer'=>'AnySpecialOffer',
'PaxMin'=>'1',
'PaxMax'=>'',
'RoomsMin'=>'1',
'RoomsMax'=>'' );
i simplified the array and you should test it and look if this is the kind of result you are looking for.
Also look for ordering errors like the example shown in php.net
This question already has answers here:
PHP json_decode() returns NULL with seemingly valid JSON?
(29 answers)
Closed 4 months ago.
There is a strange behaviour with json_encode and json_decode and I can't find a solution:
My php application calls a php web service. The webservice returns json that looks like this:
var_dump($foo):
string(62) "{"action":"set","user":"123123123123","status":"OK"}"
now I like to decode the json in my application:
$data = json_decode($foo, true)
but it returns NULL:
var_dump($data):
NULL
I use php5.
The Content-Type of the response from the webservice: "text/html; charset=utf-8" (also tried to use "application/json; charset=utf-8")
What could be the reason?
Well, i had a similar issue and the problems was the PHP magic quotes in the server... here is my solution:
if(get_magic_quotes_gpc()){
$param = stripslashes($_POST['param']);
}else{
$param = $_POST['param'];
}
$param = json_decode($param,true);
EDIT:
Just did some quick inspection of the string provided by the OP. The small "character" in front of the curly brace is a UTF-8 B(yte) O(rder) M(ark) 0xEF 0xBB 0xBF. I don't know why this byte sequence is displayed as here.
Essentially the system you aquire the data from sends it encoded in UTF-8 with a BOM preceding the data. You should remove the first three bytes from the string before you throw it into json_decode() (a substr($string, 3) will do).
string(62) "{"action":"set","user":"123123123123","status":"OK"}"
^

This is the UTF-8 BOM
As Kuroki Kaze discovered, this character surely is the reason why json_decode fails. The string in its given form is not correctly a JSON formated structure (see RFC 4627)
Print the last json error when debugging.
json_decode( $so, true, 9 );
$json_errors = array(
JSON_ERROR_NONE => 'No error has occurred',
JSON_ERROR_DEPTH => 'The maximum stack depth has been exceeded',
JSON_ERROR_CTRL_CHAR => 'Control character error, possibly incorrectly encoded',
JSON_ERROR_SYNTAX => 'Syntax error',
);
echo 'Last error : ', $json_errors[json_last_error()], PHP_EOL, PHP_EOL;
Also use the json.stringify() function to double check your JSON syntax.
None of the solutions above worked for me, but html_entity_decode($json_string) did the trick
Try this
$foo = utf8_encode($foo);
$data = json_decode($foo, true);
make sure that if you sent the data by POST / GET, the server has not escape the quotes
$my_array = json_decode(str_replace ('\"','"', $json_string), true);
"{"action":"set","user":"123123123123","status":"OK"}"
This little apostrophe in the beginning - what is it? First symbol after the doublequote.
I had the similar problem in a live site. In my local site it was working fine. For fixing the same I Just have added the below code
json_decode(stripslashes($_GET['arr']));
I just put this
$result = mb_convert_encoding($result,'UTF-8','UTF-8');
$result = json_decode($result);
and it's working
Yesterday I spent 2 hours on checking and fixing that error finally I found that in JSON string that I wanted to decode were '\' slashes. So the logical thing to do is to use stripslashes function or something similiar to different PL.
Of course the best way is sill to print this var out and see what it becomes after json_decode, if it is null you can also use json_last_error() function to determine the error it will return integer but here are those int described:
0 = JSON_ERROR_NONE
1 = JSON_ERROR_DEPTH
2 = JSON_ERROR_STATE_MISMATCH
3 = JSON_ERROR_CTRL_CHAR
4 = JSON_ERROR_SYNTAX
5 = JSON_ERROR_UTF8
In my case I got output of json_last_error() as number 4 so it is JSON_ERROR_SYNTAX. Then I went and take a look into the string it self which I wanted to convert and it had in last line:
'\'title\' error ...'
After that is really just an easy fix.
$json = json_decode(stripslashes($response));
if (json_last_error() == 0) { // you've got an object in $json}
I had such problem with storage json-string in MySQL.
Don't really know why, but using htmlspecialchars_decode berofe json_decode resolved problem.
Non of these solutions worked for me.
What DID eventually work was checking the string encoding by saving it to a local file and opening with Notepad++.
I found out it was 'UTF-16', so I was able to convert it this way:
$str = mb_convert_encoding($str,'UTF-8','UTF-16');
Maybe you use thing as $ ${: these chars should be quoted.
I was having this problem, when I was calling a soap method to obtain my data, and then return a json string, when I tried to do json_decode I just keep getting null.
Since I was using nusoap to do the soap call I tried to just return json string and now I could do a json_decode, since I really neaded to get my data with a SOAP call, what I did was add ob_start() before include nusoap, id did my call genereate json string, and then before returning my json string I did ob_end_clean(), and GOT MY PROBLEM FIXED :)
EXAMPLE
//HRT - SIGNED
//20130116
//verifica se um num assoc deco é valido
ob_start();
require('/nusoap.php');
$aResponse['SimpleIsMemberResult']['IsMember'] = FALSE;
if(!empty($iNumAssociadoTmp))
{
try
{
$client = new soapclientNusoap(PartnerService.svc?wsdl',
array(
// OPTS
'trace' => 0,
'exceptions' => false,
'cache_wsdl' => WSDL_CACHE_NONE
)
);
//MENSAGEM A ENVIAR
$sMensagem1 = '
<SimpleIsMember>
<request>
<CheckDigit>'.$iCheckDigitAssociado.'</CheckDigit>
<Country>Portugal</Country>
<MemberNumber">'.$iNumAssociadoDeco.'</MemberNumber>
</request>
</SimpleIsMember>';
$aResponse = $client->call('SimpleIsMember',$sMensagem1);
$aData = array('dados'=>$aResponse->xpto, 'success'=>$aResponse->example);
}
}
ob_end_clean();
return json_encode($aData);
I don't know Why?
But this work:
$out = curl_exec($curl);
$out = utf8_encode($out);
$out = str_replace("?", "", $out);
if (substr($out,1,1)!='{'){
$out = substr($out,3);
}
$arResult["questions"] = json_decode($out,true);
without utf8_encode() - Don't work
Check the encoding of your file. I was using netbeans and had to use iso windows 1252 encoding for an old project and netbeans was using this encoding since then for every new file. json_decode will then return NULL. Saving the file again with UTF-8 encoding solved the problem for me.
In Notepad++, select Encoding (from the top menu) and then ensure that "Encode in UTF-8" is selected.
This will display any characters that shouldn't be in your json that would cause json_decode to fail.
Try using json_encode on the string prior to using json_decode... idk if will work for you but it did for me... I'm using laravel 4 ajaxing through a route param.
$username = "{username: john}";
public function getAjaxSearchName($username)
{
$username = json_encode($username);
die(var_dump(json_decode($username, true)));
}
You should try out json_last_error_msg(). It will give you the error message and tell you what is wrong. It was introduced in PHP 5.5.
$foo = "{"action":"set","user":"123123123123","status":"OK"}";
$data = json_decode($foo, true);
if($data == null) {
throw new Exception('Decoding JSON failed with the following message: '
. json_last_error_msg());
}
// ... JSON decode was good => Let's use the data
Before applying PHP related solutions, validate your JSON format. That may be the problem. Try below online JSON format validator. If your JSON format is invalid, correct it first, because PHP doesn't decode invalid JSON strings.

Laravel specific answer:
I got the same issue in Laravel. And this did the trick for me
$result = json_decode($result->getContent(), true);
In my case, when I was printing to the screen, json was fine and I copied and decode with json_deocode() function. It was working fine. But, when I was trying to put jsonString directly in the function, it was returning null because quotes were coming like these ". So I used htmlspecialchars_decode() function and now it is working fine.
I am new here, so if I am making any mistakes in writing answer then sorry for that. I hope it'll help somebody.
Sometimes the problem is generated when the content is compressed, so adding the Accept-Encoding: identity header can solve the problem without having to wrangle with the response.
$opts = array(
'http' =>
array(
'header' =>
array(
'Accept-Encoding: identity',
),
),
);
$context = stream_context_create($opts);
$contents = file_get_contents('URL', false, $context);
i had a similar problem, got it to work after adding '' (single quotes) around the json_encode string. Following from my js file:
var myJsVar = <?php echo json_encode($var); ?> ; -------> NOT WORKING
var myJsVar = '<?php echo json_encode($var); ?>' ; -------> WORKING
just thought of posting it in case someone stumbles upon this post like me :)
