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 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.
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;
below is my 'script.json' file with json array and i want the values of webUserid and webPassword
{
"totalSize":2,
"webUserId":"abc",
"webPassword":"def",
"operation":"send",
"testMode":true,
"records":[
{
"phoneNumber":"1908908399",
"message":"Happy Birthday",
"Id":"a0YL0000008QYunMAG",
"deviceId":"ABCDEFXABCDEF"
}
]
}
I tried below one but not getting the result
<?php
$jsonString=file_get_contents("script.json");
$decoded=json_decode($jsonString,true);
foreach($decoded->data as $name){
echo $name->totalSize;
}
?>
Zarif, try the below code, its working 100%......... :)
<?php
$jsonString=file_get_contents("script.json");
$decoded=array(json_decode($jsonString,true));
foreach($decoded as $name){
echo $name['totalSize'];
}
?>
There's no need for a foreach loop in your current example, as you only have one level.
Your main problem is you're trying to use the result of your json_decode as an object when you've previously stated you want the result as an associative array.
The 2nd param of json_decode specifies what format the return value is in, so as you've done
$decoded = json_decode($jsonString, true);
you'll receive an array, which you could access like
echo $decoded['totalSize'];
if you wanted to treat it as on object as you've done in your question, either state false or omit a 2nd param in json_decode (it's false by default anyway), and that'll let you do what you're trying to do:
$decoded = json_decode($jsonString);
$decoded->totalSize;
lets say that
$myJSON = yourPostedJSON.
$myJSON = json_decode($myJSON, true);
echo $myJSON['webUserId'];
echo $myJSON['webPassword'];
I've have this list of products in JSON that needs to be decoded:
"[{"productId":"epIJp9","name":"Product A","amount":"5","identifier":"242"},{"productId":"a93fHL","name":"Product B","amount":"2","identifier":"985"}]"
After I decode it in PHP with json_decode(), I have no idea what kind of structure the output is. I assumed that it would be an array, but after I ask for count() it says its "0". How can I loop through this data so that I get the attributes of each product on the list.
Thanks!
To convert json to an array use
json_decode($json, true);
You can use json_decode() It will convert your json into array.
e.g,
$json_array = json_decode($your_json_data); // convert to object array
$json_array = json_decode($your_json_data, true); // convert to array
Then you can loop array variable like,
foreach($json_array as $json){
echo $json['key']; // you can access your key value like this if result is array
echo $json->key; // you can access your key value like this if result is object
}
Try like following codes:
$json_string = '[{"productId":"epIJp9","name":"Product A","amount":"5","identifier":"242"},{"productId":"a93fHL","name":"Product B","amount":"2","identifier":"985"}]';
$array = json_decode($json_string);
foreach ($array as $value)
{
echo $value->productId; // epIJp9
echo $value->name; // Product A
}
Get Count
echo count($array); // 2
Did you check the manual ?
http://www.php.net/manual/en/function.json-decode.php
Or just find some duplicates ?
How to convert JSON string to array
Use GOOGLE.
json_decode($json, true);
Second parameter. If it is true, it will return array.
You can try the code at php fiddle online, works for me
$list = '[{"productId":"epIJp9","name":"Product A","amount":"5","identifier":"242"},{"productId":"a93fHL","name":"Product B","amount":"2","identifier":"985"}]';
$decoded_list = json_decode($list);
echo count($decoded_list);
print_r($decoded_list);
I'm trying to get the "screenshotUrls" string from this piece of json:
$request_url = 'http://itunes.apple.com/search?term=ibooks&country=us&entity=software&limit=1';
$json = file_get_contents($request_url);
$decode = json_decode($json, true);
echo $decode['results'][0]['screenshotUrls'];
But I get only text "Array"
What have I done wrong?
Try
var_dump($decode['results'][0]['screenshotUrls']);
IF you get 'Array' output by PHP that means that you're trying to echo an actual array (or the string 'Array'...). That means you need to get a specific index value.
Since $decode['results']['0']['screenshotUrls'] is an array, if you want just a string (say, delimited by commas), you could use
echo implode(",", $decode['results']['0']['screenshotUrls']);
This will iterate over the array, and return a comma-separated string of all the URLs.
Do a var_dump($decode['results']['0']['screenshotUrls']). You'll find that the ['screenshotUrls'] is actually an Array, containing one or more URLs (hence the plural 'urls' in its name).
There's nothing wrong with your code so far, but $decode['results'][0]['screenshotUrls'] is an array of all the URLs to screenshots. To go through each one individualy, you need to do:
forearch ($decode['results'][0]['screenshotUrls'] as $url) {
// Do stuff here
}
