Although this may seem like a general question, how can you extract content from a URL such as (http://api.openweathermap.org/data/2.5/weather?q=London,uk) so that it can be formatted and used in the form of an array for each element in PHP? More specifically, how can I extract information from websites in general?
To get data from URL:
$content = file_get_contents('http://api.openweathermap.org/data/2.5/weather?q=London,uk');
Convert it in simple array:
$new_data = json_decode($content, true);
print_r($new_data);
$json = file_get_contents('http://api.openweathermap.org/data/2.5/weather?q=London,uk');
$array = json_decode($json, true);
var_dump($array);

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:
[{"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'm new to PHP and web programming at all.I am trying to read some json data from steam API.
Data: http://pastebin.com/hVWyLrfZ
I managed to get to single objects(I believe?).
This is my code:
<?php
$url = 'https://api.steampowered.com/IEconDOTA2_570/GetHeroes/v0001/?key=X';
$JSON = file_get_contents($url);
$data = json_decode($JSON);
$heroes = reset(reset($data));
//var_dump($heroes);
$wat = reset($heroes);
$antimage = array_values($heroes)[0];
var_dump($antimage);
?>
I want data to be in array like this:
id => name
I mean, array keys should be ids and values should be hero names.
Also,the where I set heroes variable to reset(reset($data)) seems like a bad way of doing what I want, maybe there are better ways?
You can use array_map() function to extract both id and names in two separate arrays and then use array_combine() to create a key-value pair array from the previously extracted arrays.
$url = 'https://api.steampowered.com/IEconDOTA2_570/GetHeroes/v0001/?key=X';
$JSON = file_get_contents($url);
$data = json_decode($JSON, true);
$ids = array_map(function($a) {
return $a['id'];
}, $data['result']['heroes']);
$names = array_map(function($a) {
return $a['name'];
}, $data['result']['heroes']);
$heroes = array_combine($ids, $names);
print_r($heroes);
A simpler more obvious solution is to simply loop thru it. From your pastebin, I see that your data is wrapped in two levels of array so ...
$myResult = [];
foreach ($data['result']['heroes'] as $nameId) {
$myResult[$nameId['id']] = $nameId['name'];
}
(No need to do any reset calls; that's a weird way to get the first element of an array)
Note, for this to work, you must apply the tip by #RamRaider
$data = json_decode($JSON, true);
in order for json_decode to return arrays, not StdClass.
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 want to know how can i extract a word from a json encoded or decoded.
Example:
From:
{"51973658":{"id":51973658,"name":"Covrigel","profileIconId":748,"summonerLevel":30,"revisionDate":1419865098000}}
I want to see just "Covrigel".
Is that possible?
This is a simple array. You can access that by something like this,
echo $array_name['51973658']['name'];
EDIT after question change:
$json = json_decode($json_array, true);
echo $json['51973658']['name'];
All you have to do is convert it to a PHP array.
$json = '{"51973658":{"id":51973658,"name":"Covrigel","profileIconId":748,"summonerLevel":30,"revisionDate":1419865098000}}';
$json = json_decode($json, $array = true);
echo $json['51973658']['name'];
Decode the JSON as an associative array then echo the value you need.
<?php
$json = '{"51973658":{"id":51973658,"name":"Covrigel","profileIconId":748,"summonerLevel":30,"revisionDate":1419865098000}}';
$data = json_decode($json, true);
echo $data['51973658']['name'];
?>
