I got this part in an object:
[tcd_old_value] => {"14":{"name":"Nakon radnog vremena","name_changed":false,"added_cc":[],"removed_cc":["4"]},"15":{"name":"Dodatno radno vrijeme","name_changed":false,"added_cc":[],"removed_cc":["4"]}}
after json_decode
$json_object = json_decode(tcd_old_value);
I get:
stdClass Object
(
[14] => stdClass Object
(
[name] => Nakon radnog vremena
[name_changed] =>
[added_cc] => Array
(
)
[removed_cc] => Array
(
[0] => 4
)
)
[15] => stdClass Object
(
[name] => Dodatno radno vrijeme
[name_changed] =>
[added_cc] => Array
(
)
[removed_cc] => Array
(
[0] => 4
)
)
)
I'm trying to count how many indexes are in this object (obviously the result should be 2)
$result = count($json_object);
echo $result //returns 1
Any insight on what I'm doing wrong here?
You cannot use count() in this case, because you have an object and not an array.
You may use the second parameter of json_decode() to have the JSON converted to an associative array:
$json_object = json_decode(tcd_old_value, true);
$result = count($json_object);
echo $result; // Now prints 2
Keep in mind that $json_object is no longer an object, but an array instead.
As per the document count
Returns the number of elements in array_or_countable. If the parameter
is not an array or not an object with implemented Countable interface,
1 will be returned. There is one exception, if array_or_countable is
NULL, 0 will be returned.
You may need to use
json_decode('json', true);
to convert as an array

I cannot find how to get the results from this JSON post in PHP.
stdClass Object
(
[api_job_id] => 398438bf-c0a5-46fc-8774-70d2425e1ce7
[data] => Array
(
[0] => stdClass Object
(
[type] => MESSAGE
[message_id] => 15125005817130024103
[to] => xxx
[error_code] => 0
[#meta] => stdClass Object
(
[error] => stdClass Object
(
[error_desc] => NO_USER
[error_code] => 9
)
)
)
)
)
as you can see the meta has a # icon before it.
I can read all data to vars instead of the data in the #meta
I tried many ways like:
$result = $arrayResponse['#meta']['error']['error_desc'];
it's not working in PHP because of the # icon.
Any idea how I can get the values from these errors in #meta?
To refer to an object attribute with a name that doesn't make a valid variable, you can use braces:
$foo = json_decode($string);
var_dump($foo->{'#meta'});
Or pass a truthy value to json_decode() as the second argument, and you'll get back an array instead of an object:
$foo = json_decode($string, true);
var_dump($foo['#meta']);
I have this code :
<?php
$array = array ( array ('pcs'=>'23', 'kg'=>'3'),
array ('pcs'=>'24', 'kg'=>'4'),
array ('pcs'=>'25', 'kg'=>'5'));
echo '<pre>';
print_r($array);
$array = json_encode($array);
echo $array;
$array = json_decode($array);
echo '<pre>';
print_r($array);
?>
and here's the output :
Array
(
[0] => Array
(
[pcs] => 23
[kg] => 3
)
[1] => Array
(
[pcs] => 24
[kg] => 4
)
[2] => Array
(
[pcs] => 25
[kg] => 5
)
)
[{"pcs":"23","kg":"3"},{"pcs":"24","kg":"4"},{"pcs":"25","kg":"5"}]
Array
(
[0] => stdClass Object
(
[pcs] => 23
[kg] => 3
)
[1] => stdClass Object
(
[pcs] => 24
[kg] => 4
)
[2] => stdClass Object
(
[pcs] => 25
[kg] => 5
)
)
why my array becomes stdClass Object? can I still manipulates stdClass Object just like an array?
UPDATE : I got this error when I tried to echo-ing $array[0]['pcs'] :
Fatal error: Cannot use object of type stdClass as array in /home/*** on line **
The "problem" has nothing in common with json_encode, but rather with json_decode.
This will return an array:
$array = json_decode($array, true);
From the PHP Manual:
json_decode() is use to Decodes a JSON string:
When you use second param as TRUE in json_decode():
Returned objects will be converted into associative arrays.
Solution for you:
$array = json_decode($array,TRUE); // use second param as TRUE in your code.
Some Basic Examples for Understanding:
Example 1:
<?php
$json = '{"test":"test","test2":"test2"}'; // json string
echo "<pre>";
print_r(json_decode($json)); // without using second param
?>
Result (return as object):
stdClass Object
(
[test] => test
[test2] => test2
)
Example 2:
<?php
$json = '{"test":"test","test2":"test2"}';
echo "<pre>";
print_r(json_decode($json,TRUE)); // with second param true
?>
Result:
Array
(
[test] => test
[test2] => test2
)
That's standard php behavior. json_decode() will convert incoming data to an array of objects of class stdClass.
You can still access all elements but you have to do it more OOP:
echo $array[0]->pcs;
echo $array[0]->kg;
If you want json_decode() to reproduce your initial array use second option of the function:
$array = json_decode($array, true);
echo $array[0]['pcs'];
echo $array[0]['kg'];
Is this Normal?
Yes, because json_decode basically returns an object and since you didn't specify the second parameter it should return an object and not an array.
According to docs
When TRUE, returned objects will be converted into associative arrays.
so to make it return an array, is to make the second parameter equal to true.
$array = json_decode($array,true);
I have a object as shown below and i want to extract data from
stdClass Object
(
[day1] => stdClass Object
(
[0] => 12.06.2015
[part1] => Array
(
[0] => 19.00
[1] => 22.00
)
[part2] => Array
(
[0] =>
[1] =>
)
)
)
How will i get date as shown above with key 0. I can get others as
$string->day1->part1[0]
How can i get date "12.06.2015" ? This seems to be complicated.
JSON string for reference
{"day1":{"0":"12.06.2015","part1":["19.00","22.00"],"part2":["",""]},"day2":{"0":"13.06.2015","part1":["09.00","12.00"],"part2":["13.00","17.00"]}}
used json_decode to decode it.
You can use this:
echo $string->day1->{0};
Or my preference, decode as an array with the second argument set to true in json_decode() to use this:
echo $string['day1'][0];
I would like to save my count result when ElasticSearch return this line:
{"took":13,"timed_out":false,"_shards":{"total":5,"successful":5,"failed":0},"hits":{"total":2242,"max_score":1.0,"hits":[{"_index":"
I wish to save the total result into a variable, but I don't found the good regex rule to save "2242".
Why do you think you need a regex? Just use json_decode and access it like this; closed your JSON for this example:
$raw_json = '{"took":13,"timed_out":false,"_shards":{"total":5,"successful":5,"failed":0},"hits":{"total":2242,"max_score":1.0,"hits":[{"_index":"999999"}]}}';
$decoded_json = json_decode($raw_json);
echo '<pre>';
print_r($decoded_json);
echo '</pre>';
The output would be this:
stdClass Object
(
[took] => 13
[timed_out] =>
[_shards] => stdClass Object
(
[total] => 5
[successful] => 5
[failed] => 0
)
[hits] => stdClass Object
(
[total] => 2242
[max_score] => 1
[hits] => Array
(
[0] => stdClass Object
(
[_index] => 999999
)
)
)
)
Then knowing that you just access the total under hits like this:
$hits_total = $decoded_json->hits->total;
echo $hits_total;
Or if objects are not easy for you to parse, just set json_decode to return an array by setting the second parameter to true.
$decoded_json = json_decode($raw_json, true);
And then access it like this:
$hits_total = $decoded_json['hits']['total'];
echo $hits_total;
You could use the count API facility in ElasticSearch to reduce data size for parsing.
But anyway you should use json_decode to parse returned results.
I have a json response which is decode into an array $data as
stdClass Object ( [outboundSMSMessageRequest] => stdClass Object ( [deliveryInfoList] => stdClass Object ( [deliveryInfo] => stdClass Object ( [address] => 8606142527 [deliveryStatus] => Submitted ) [resourceURL] => http://api-testmobile.com/smsmessaging/1/outbound/OPNHSE/requests/urn:uuid:0f55fd13-a419-4ad9-adec-3dcf63ca39c1/deliveryInfos ) [senderAddress] => OPNHSE [outboundSMSTextMessage] => stdClass Object ( [message] => Sam has requested a payment of Rs 10.00. ) [clientCorrelator] => [receiptRequest] => stdClass Object ( [notifyURL] => [callbackData] => ) [senderName] => [resourceURL] => http://api-openhouse.testingmobile.com/smsmessaging/1/outbound/OPNHSE/requests/urn:uuid:0f5-a419-4ad9-adec-3dcf63ca39c1 ) )
I want to store [deliveryStatus] => Submitted this "Submitted" into a variable.
I have tried $dStatus=$data['deliveryStatus']; but its not working :(
UPDATE
I tried to convert it to associative array by json_decode($data,TRUE);
Array ( [outboundSMSMessageRequest] => Array ( [deliveryInfoList] => Array ( [deliveryInfo] => Array ( [address] => 98989 [deliveryStatus] => Submitted ) [resourceURL] => http://api-otest.com/smsmessaging/1/outbound/OPNHSE/requests/urn:uuid:3b277b5b-cf79-4551-872f-16674499bc09/deliveryInfos ) [senderAddress] => OPNHSE [outboundSMSTextMessage] => Array ( [message] => sam has requested a payment of Rs 100.00 through payt.me . Kindly clickhttps://www.test.me/test to pay. ) [clientCorrelator] => [receiptRequest] => Array ( [notifyURL] => [callbackData] => ) [senderName] => [resourceURL] => http://api-test.com/smsmessaging/1/outbound/OPNHSE/requests/urn:uuid:3b277b5b-cf79-4551-872f-16674499bc09 ) )
I got this.Now how to get the deliveryStatus variable?
If you want to access it a an associative array, you should convert it like an associative array first. Pass TRUE as a second argument to json_decode function as described in docs: http://php.net/json_decode
It's because you're accessing the data in the wrong fashion. json_decode returns an object, so you need to access these fields as object properties. For example:
Instead of
$dStatus=$data['deliveryStatus'];
Try a member access format
$dStatus=$data->deliveryStatus;
If you want to access the data as an associated array, that's also quite simple.
When you call json_decode, pass true as the second parameter:
$myJson = json_decode($data,true);
Please refer to the document on json_decode for more information.
I suggest to look at the view-source of the HTML you are outputting, or to wrap the print_r in a <pre></pre> tag, so that you can see the structure more easily.
Also, the elements are of class Object, which means they are not an array, so you need to use -> to access the elements of your objects.
So if it is an object:
$data = json_decode($response);
$dStatus = $data->outboundSMSMessageRequest->deliveryInfoList->deliveryInfo->deliveryStatus;
If it is an array, then:
$data = json_decode($response, true);
$dStatus = $data['outboundSMSMessageRequest']['deliveryInfoList']['deliveryInfo']['deliveryStatus'];
You see, the deliveryStatus entry is nested in sub-objects in the first case, and in sub-arrays in the second case.
