I have the following JSON:
{
"stars":5,
"numberOfReviews":{
"total":1179,
}
}
and the following PHP:
$json = file_get_contents('url-of-json');
$obj = json_decode($json);
print $obj->stars;
This prints 5 as expected. How do I print the "total" value of 1179 from the second level in the array's hierarchy?
I've been unable to find an explanation on how to achieve this. Here's some example of what I've been trying so far:
print $obj->total
print $obj->{'numberOfReviews', 'total'}
print $obj->['numberOfReviews']['total']
print $obj->numberOfReviews{'total'}
print $obj->[1]['total']
print $obj->numberOfReviews[0]total
print $obj->total[1]
$obj->numberOfReviews is an \stdClass object too, so try it with $obj->numberOfReviews->total
$obj->numberOfReviews->total;
Or add second parameter to json_decode with true value, and use it as array.

For some strange reason I can't change the following JSON to a PHP array:
{"sides0":{"name_nl":"Voorkant100","name":"Frontside100","template_overlay":""},"sides1":{"name_nl":"Achterkant100","name":"Backside100","template_overlay":"1"}}
I've validated the json and it's valid.
First I post $product['sides'] to my page, containing:
"{\"sides0\":{\"name_nl\":\"Voorkant100\",\"name\":\"Frontside100\",\"template_overlay\":\"\"},\"sides1\":{\"name_nl\":\"Achterkant100\",\"name\":\"Backside100\",\"template_overlay\":\"1\"}}"
Then I use json_decode on it like this:
$sidearr = json_decode($product['sides'], true);
If I then do:
echo '<pre>';
print_r($sidearr);
echo '</pre>';
It prints the first part of my question.
Now I want to loop over it, but even this test shows nothing:
foreach($sidearr as $side){
echo 'test';
}
I tried testing if it even is an array with:
echo is_array($sidearr) ? 'Array' : 'not an Array';
echo "\n";
And it shows me that it is not an array. Why is that? I always thought using json_decode on a json string and add true inside the function turns it into a PHP array.
It prints the first part of my question.
Because $sidearr is a string now, decode it again, you'll get an array.
$sidearr = json_decode($sidearr, true);

Closed 4 years ago.
i have the following Json sent via ajax to test.php:
[{},{"product[]":"john","qty[]":"12","price[]":"100","total[]":"1200"},{"product[]":"juan","qty[]":"22","price[]":"3.5","total[]":"77"},{"product[]":"louis","qty[]":"99","price[]":"1.22","total[]":"120.78"},{"product[]":"paul","qty[]":"5","price[]":"2.1","total[]":"10.5"},{"product[]":"carl","qty[]":"9","price[]":"14","total[]":"126"},{"total_amount":"1533.00"}]
In my php file I am trying to loop through each individual product[], qty[], price[] and list values:
<?php
$obj = json_decode($_POST["mydata"]);
header('Content-Type: application/json');
// echo json_encode($obj[1]->{'product[]'}); //(works)
foreach($obj as $item) {
echo $item['product[]'].'<br>';
echo $item['price[]'].'<br>';
echo $item['qty[]'].'<br>';
echo $item['total[]'].'<br>';
}
?>
but this throws an error.
What is wrong in my loop?
There are a couple of things wrong with the code, the first is that you decode as objects and try and use this as an array. You need to pass true as the second parameter to json_decode() to make it an associative array.
The second is that your array contains elements which don't have all of the details. The last element only has "total_amount", so none of the other fields exist. This is why I use
if ( isset($item['product[]'])){
to check the object before outputting the data...
$obj = json_decode($_POST["mydata"], true);
header('Content-Type: application/json');
foreach($obj as $item) {
if ( isset($item['product[]'])){
echo $item['product[]'].'<br>';
echo $item['price[]'].'<br>';
echo $item['qty[]'].'<br>';
echo $item['total[]'].'<br>';
}
}
Pass true as second argument to json_decode.
Per the documentation:
assoc
When TRUE, returned objects will be converted into associative arrays.
So your code becomes:
$obj = json_decode($_POST["mydata"], true);
Also note that the first entry in your array is empty, so you're gonna have to check for that.
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 ?

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 decode the following JSON using php json_decode function.
[{"total_count":17}]
I think the square brackets in output is preventing it. How do I get around that? I can't control the output because it is coming from Facebook FQL query:
https://api.facebook.com/method/fql.query?format=json&query=SELECT%20total_count%20FROM%20link_stat%20WHERE%20url=%22http://www.apple.com%22
PHP's json_decode returns an instance of stdClass by default.
For you, it's probably easier to deal with array. You can force PHP to return arrays, as a second parameter to json_decode:
$var = json_decode('[{"total_count":17}]', true);
After that, you can access the variable as $result[0]['total_count']
See this JS fiddle for an example of how to read it:
http://jsfiddle.net/8V4qP/1
It's basically the same code for PHP, except you need to pass true as your second argument to json_decode to tell php you want to use it as associative arrays instead of actual objects:
<?php
$result = json_decode('[{"total_count":17}]', true);
print $result[0]['total_count'];
?>
if you don't pass true, you would have to access it like this: $result[0]->total_count because it is an array containing an object, not an array containing an array.
$json = "[{\"total_count\":17}]";
$arr = Jason_decode($json);
foreach ($arr as $obj) {
echo $obj->total_count . "<br>";
}
Or use json_decode($json, true) if you want associative arrays instead of objects.
