i have searched and searched but i don't know where i'm wrong getting a value from JSON encode, can you help me? Please don't kill me, i'm a newbie :)
My php:
<?php
$data = json_decode("document.json", true);
$getit = $data["likes"];
My JSON:
[{
"title" : "MYTITLE",
"image" : "MYIMAGE",
"likes" : 0
}]
EDIT
Thanks for the help this is now working!
json_decode expects an string, not an filename - so you have first get the contents of the given file. This could be easily achieved with file_get_contents.
Your current json structure contains an array(with currently only one element), which contains an object. So if you want the likes, you have to read the first element of the result array and of that(an associative array), the likes.
$data = json_decode(file_get_contents($filename), true);
$likes = $data[0]['likes'];
If you have more than one object in the given json file, you could loop over the data with foreach
foreach ($data as $element) {
echo "likes of {$element['title']}: {$element['likes']}\n";
}
For json_decode you have to pass JSON string, not a file name. Use file_get_contents to get JSON content and then decode it.
$data = json_decode(file_get_contents('document.json'), true);
$getit = $data[0]['likes'];
Your JSON is an array of objects, you first need to access the first element of your array :
$data[0]
Then you can access the key you want :
$getit = $data[0]['likes'];
Plus, as stated in a comment above, you need to pass a string to json encode, here is an code sample that should suit your needs :
<?php
$data = json_decode(file_get_contents('document.json'), true);
$getit = $data[0]["likes"];
Hope this helps.

$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:

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!
Here is the JSON response in which I need your help.
I need to access "age" key inside 'attribute'.
I really tried every possible ways that i could get. So can u please try to help me out :)
Another option, is that when you call json_decode by default you get a php object, however, if you add an optional boolean parameter you get an array which can be easier in situations like this to access nested elements.
// $data is the original json string
$json = json_decode($data, true);
print_r($json);
There are 2 ways I can see checking the json you just provided, one is by iterating the array, and the other one is accessing it by index:
$json = json_decode($response);
foreach ($json as $item) {
$value = $item->item->attribute->age->value;
var_dump($value);
}
the other way:
$value = $json[0]->item->attribute->age->value;
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'];
{
"firstName":"sunny",
"religion": {"holly":"1",
"bolly":"colly",
"nolly":"only"
},
"lonely":"money",
"ronney":"leone",
"honey":"bunny"
}
This is my JSON. I want to get all the data from this and to be stored into some php variables or an array.
I Used the following code to extract data from my JSON. I decoded it first and then stored it in an array..
$val_array = json_decode($jsondata, true);
echo $jsondata;
$AAA = $val_array->firstName;
$BBB = $val_array->religion;
$CCC_id = $val_array->bolly;
$DDD = $val_array->nolly;
$CCC_id = $val_array->lonely;
$DDD = $val_array->ronney;
But it didn't give me any output. Then I used this.
foreach($data['val_array'] as $item)
{
echo $item[0];
}
}
No output. Help??
You get this second param wrong:
$val_array = json_decode($jsondata, true);
$AAA = $val_array['firstName'];
OR
$val_array = json_decode($jsondata, false);
$AAA=$val_array->firstName;
Your JSON is not valid. Remove commas after last elements:
{
"firstName" : "sunny",
"religion" : {
"holly" : "1",
"bolly" : "colly",
"nolly" : "only" # Here
},
"lonely" : "money",
"ronney" : "leone",
"honey" : "bunny" # And here
}
You have an error in your JSON :
"nolly":"only",
"honey":"bunny",
remove the ',' at the end of these 2 lines, then json_decode() will return you an array.
And if you want an object, do not pass second argument to json_decode()
json_decode by default returns an object yet since you are setting the second parameter to true, you are given an associative array with the information instead.
It basically comes down to the fact that either you do not need to fill in the second parameter and get the object you want, or you work with arrays when you set the parameter to true.
A little reading on PHP.net will do you good for further reference since their documentation is well presented, usually commented by others with helpful suggestions and quite clean as well!
$val_array = json_decode($jsondata, true);
$m1=$val_array['firstName'];
$m2=$val_array['lonely'];
$m3=$val_array['ronney'];
$m4=$val_array['honey'];
$m4=$val_array['religion']['holly'];
$m5=$val_array['religion']['bolly'];
$m6=$val_array['religion']['nolly'];
BY using this, we don't have to use foreach loops or inner loops for accessing data. Viola!
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
