I have an API that takes parameters from a post through JSON and I want to extract one of the values in an array for a key value pair. However, despite many attempts, I can't get it to work.
Here is my code:
$json = file_get_contents('php://input');
$request = json_decode($json, true);
$parameters = $request["result"]["parameters"];
When I log $parameters to a text file, it log as
{"numberofhits":"5"}
However, my efforts to capture the value 5 are not working:
$numhits = $json['numberofhits']; logs as empty.
So does:
$numhits = $parameters->numberofhits;
How can I capture the value 5 in a variable?
From your code above $json is a string and not a json object, your should use $request to access numberofhits
$request['numberofhits']
If your $parameters just shows {"numberofhits":"5"}, this means your post request just returned a json of a json. Try json decoding $parameters again like json_decode($parameters, true); and log that result. It should log the desired array.

I am parsing data from webhook using this:
$data = json_decode(file_get_contents('php://input'), true);
So I have array of data in json file. How can I can get all of fields be as variables in json (Like { time: 'now' } be variable $time='now';
PHP has an extract function that will convert array keys into variables. Whether that is a good idea is a totally different question.
$data = json_decode(file_get_contents('php://input'), true)
return arrray expample array('time':'10:00');
you can get variable example
echo $data['time'];
oupt put => 10:00
$json = file_get_contents('module=API&method=Referrers.getReferrerType&format=json&period=day&date=yesterday&disableLink=1&idSite=3');
$data = json_decode($json,true);
json data:
[{"label":"Direct Entry","nb_uniq_visitors":526,"nb_visits":593,"nb_actions":768,"nb_users":0,"max_actions":32,"sum_visit_length":83153,"bounce_count":513,"nb_visits_converted":0,"segment":"referrerType==direct"},{"label":"Search Engines","nb_uniq_visitors":230,"nb_visits":235,"nb_actions":631,"nb_users":0,"max_actions":71,"sum_visit_length":52233,"bounce_count":150,"nb_visits_converted":0,"segment":"referrerType==search","idsubdatatable":2},{"label":"Websites","nb_uniq_visitors":7,"nb_visits":7,"nb_actions":20,"nb_users":0,"max_actions":5,"sum_visit_length":835,"bounce_count":1,"nb_visits_converted":0,"segment":"referrerType==website","idsubdatatable":3}]
I'm trying to display each label for the referrer type.
Direct Entry
Search Engines
Websites
$data[0]->label; doesn't work
$data->label; doesn't work
$data->label[0]; doesn't work
You passed true to the second parameter to json_decode(). That makes it return an associative array. Thus, you can simply use the data like this :
$data[0]["label"]
You can try this, as you're converting the json data to associative array (nested), by passing true into the 2nd argument of json_decode method:
$json = "[{\"label\":\"Direct Entry\",\"nb_uniq_visitors\":526,\"nb_visits\":593,\"nb_actions\":768,\"nb_users\":0,\"max_actions\":32,\"sum_visit_length\":83153,\"bounce_count\":513,\"nb_visits_converted\":0,\"segment\":\"referrerType==direct\"},{\"label\":\"Search Engines\",\"nb_uniq_visitors\":230,\"nb_visits\":235,\"nb_actions\":631,\"nb_users\":0,\"max_actions\":71,\"sum_visit_length\":52233,\"bounce_count\":150,\"nb_visits_converted\":0,\"segment\":\"referrerType==search\",\"idsubdatatable\":2},{\"label\":\"Websites\",\"nb_uniq_visitors\":7,\"nb_visits\":7,\"nb_actions\":20,\"nb_users\":0,\"max_actions\":5,\"sum_visit_length\":835,\"bounce_count\":1,\"nb_visits_converted\":0,\"segment\":\"referrerType==website\",\"idsubdatatable\":3}]";
$data = json_decode($json, true);
print_f($data[0]['label']);
Hope this helps!
I have the url http://pubapi.cryptsy.com/api.php?method=singleorderdata&marketid=132 which leads to an array.
I want to get the value of the first 'sellorders' which in this case is: 0.00000048 and store it in the variable $sellorderprice.
Can anyone help?
Thanks.
Just access the url contents thru file_get_contents. Your page actually return a JSON string, to get those values into meaningful data, decode it thru json_decode, after that access the data needed accordingly:
$url = 'http://pubapi.cryptsy.com/api.php?method=singleorderdata&marketid=132';
$data = json_decode(file_get_contents($url), true);
$sellorderprice = $data['return']['DOGE']['sellorders'][0]['price'];
echo $sellorderprice;
That code actually points directly to index zero 0 which gets the first price. If you need to get all items an just simply echo them all you need to iterate all items thru foreach:
foreach($data['return']['DOGE']['sellorders'] as $sellorders) {
echo $sellorders['price'], '<br/>';
}
Its simple, you just have to decode json like this:
$json = file_get_contents("http://pubapi.cryptsy.com/api.php?method=singleorderdata&marketid=132");
$arr = json_decode($json, true);
$sellorderprice = $arr['return']['DOGE']['sellorders'][0]['price'];
I'm writing a simple PHP script that makes an API call that returns JSON. However, I'm having trouble figuring out how to take that JSON string, convert it into a dictionary, and access nested dictionaries/data within it.
Here's what I have so far:
<?php
$id = $_REQUEST['id'];
$url = http://exampleURLThatReturnsJSONString.com
$rawData = file_get_contents($url);
I've read that you should use something like $decodedData = json_decode($rawData)
, but I'm not sure what to do next, especially if I want to access nested dictionaries with a key like Schedule.
Any help would be greatly appreciated, thanks!
json_decode($json, $assoc = false) converts the json string into an object by default, or into an array if you specify $assoc = true
If you have $assoc = false then you must access the values by $decoded_data->key. Whereas if you have $assoc = true then you can do $decoded_data['key']
You can just access the decoded data like this:
echo $decodedData['key'];
This wil echo the value of the item in the dictionary with key 'key'. Nested values can be accessed like this:
echo $decodedData['key1']['key2']['...'];
You can always use var_dump to show what's inside the result. Also, read the documentation on json_decode for more information.
json_decode return array or object to which access is like to array.

I am trying to read certain values from a json string in php, I am able to do a simple json string with only one value such as
$json = '{"value":"somevalue"}';
Using this:
<?php
$json = '{"value":"somevalue"}';
$obj = json_decode(json_encode($json));
print $obj->{'value'};
?>
But when i try an get a value from the following json string it throws an error...
$json = '{"field": "title","rule": {"required": "true","minlength": "4","maxlength": "150" }}';
I validated the json on JSONlint but not sure how to access the values within this with php.
Thanks
You can try this:
$json = '{"field": "title","rule": {"required": "true","minlength": "4","maxlength": "150" }}';
//since $json is a valid json format you needn't encode and decode it again
$obj = json_decode($json);
print_r($obj->filed);
print_r($obj->rule);
You can pass true as a second parameter to json_decode() to get the results as an array
$my_arr = json_decode($json, true);
var_dump($my_arr);
Should help you. You can then step through the array as you would normally.
use var_dump to print out the object with all it's members and hierarchy. you should then be able to find the value you are looking for
