I have an API which is returning some nested JSON data with multiple levels. My PHP code to loop through is below but I'm not getting any output:
$data = json_decode($output, true);
foreach($data as $item){
$title = $item->events->name->text;
echo $title;
}
An example of the data can be found here: http://i.imgur.com/Y55vl7n.png
I am trying to print the text name of each of the events (events->name->text)
There is a problem in your code, when you decode the json string, you use:
$data = json_decode($output, true);
It is converting everything to "array" (http://php.net/manual/en/function.json-decode.php), so you cannot access it like if they were objects.
You have to do:
foreach($data as $item){
$title = $item["events"]["name"]["text"];
echo $title;
}
Hope this helps!

I'm using iTunes RSS generator to get HOT tracks, now I'm using following way to parse JSON:
<?php
$json_string = 'https://rss.itunes.apple.com/api/v1/in/apple-music/hot-tracks/all/10/explicit.json';
$jsondata = file_get_contents($json_string);
$obj = json_decode($jsondata,true);
$cltn = $obj['feed']['results'][0]['collectionName'];
echo $cltn;
?>
Now, as we know that It'll return only 1 collectionName.
JSON request is returning 10 results. How can I get them all using foreach loop? I've used several ways but no success.
Since you didn't give the output of the array I assume the [0] index is what needs to be iterated.
You need to foreach the $obj['feed']['results'] by doing:
Foreach($obj['feed']['results'] as $cltn){
Echo $cltn['collectionName'];
}
Foreach over the results:
foreach ($obj['feed']['results'] as $result) {
echo $result['collectionName'] . '<br>' . PHP_EOL;
}
Based on the code you provided you can iterate the results to get all possible information from the artist/track list, for example:
$json_string = 'https://rss.itunes.apple.com/api/v1/in/apple-music/hot-tracks/all/10/explicit.json';
$jsondata = file_get_contents($json_string);
$obj = json_decode($jsondata,true);
$cltn = $obj['feed']['results'];
function test_print($item, $key)
{
echo "<strong>".$key."</strong>: ".$item."<br>";
}
foreach($cltn as $key => $c) {
echo "Result No ".($key+1)."<br>";
array_walk_recursive($c, 'test_print');
}
in case you only want to show artistName and collectionName you can slightly modify the above example:
$json_string = 'https://rss.itunes.apple.com/api/v1/in/apple-music/hot-tracks/all/10/explicit.json';
$jsondata = file_get_contents($json_string);
$obj = json_decode($jsondata,true);
$cltn = $obj['feed']['results'];
foreach($cltn as $c) {
echo $c['artistName'].": ".$c['collectionName']."<br>";
}
You can try all the above in PHP Fiddle
Try like this way with foreach() to iterate your array in key=>value manner as you've decoded the json as an array not an object in php.
<?php
$json_string = 'https://rss.itunes.apple.com/api/v1/in/apple-music/hot-tracks/all/10/explicit.json';
$jsondata = file_get_contents($json_string);
$array = json_decode($jsondata,true);
# printing resulted array just for debugging purpose
print '<pre>';
print_r($array);
print '</pre>';
foreach($array['feed']['results'] as $key=>$value){
echo $value['collectionName'].'<br/>';
}
?>
I have a JSON with the Following structure.
{
"1":{"Itemname":"dtfg","unitprice":"12","Qty":"4","price":"$48.00"},
"2":{"Itemname":"kjh","unitprice":"45","Qty":"7","price":"$315.00"},
"3":{"Itemname":"yjk","unitprice":"76","Qty":"8","price":"$608.00"},
"4":{"Itemname":"hgj","unitprice":"4","Qty":"45","price":"$180.00"}
}
I need the Itemname to be made into a PHP array, Unitprice into another one, Qty to another one and price to another one. How do I do that?
$getArray = get_object_vars(json_decode($json));
print_r($getArray);
echo $getArray[1]->Itemname;
echo $getArray[1]->unitprice;
you require get_object_vars as well for achieving your requirement.
<?php
$json =<<<JSONLIVES
{
"1":{"Itemname":"dtfg","unitprice":"12","Qty":"4","price":"$48.00"},
"2":{"Itemname":"kjh","unitprice":"45","Qty":"7","price":"$315.00"},
"3":{"Itemname":"yjk","unitprice":"76","Qty":"8","price":"$608.00"},
"4":{"Itemname":"hgj","unitprice":"4","Qty":"45","price":"$180.00"}
}
JSONLIVES;
$items = json_decode($json, TRUE);
$item_names = array();
foreach($items as $key => $item) {
$item_names[] = $item['Itemname'];
}
Or Php >= 5.5
print_r(array_column($items, 'Itemname'));
You need a function called json_decode() to convert your json data into PHP array
$json = {
"1":{"Itemname":"dtfg","unitprice":"12","Qty":"4","price":"$48.00"},
"2":{"Itemname":"kjh","unitprice":"45","Qty":"7","price":"$315.00"},
"3":{"Itemname":"yjk","unitprice":"76","Qty":"8","price":"$608.00"},
"4":{"Itemname":"hgj","unitprice":"4","Qty":"45","price":"$180.00"}
};
var_dump(json_decode($json));
You need to decode your Json by PHP's json_decode()
$decodeJson will return object then you can read Itemname and other values by using $val->Itemname in foreach loop
$json = '{
"1":{"Itemname":"dtfg","unitprice":"12","Qty":"4","price":"$48.00"},
"2":{"Itemname":"kjh","unitprice":"45","Qty":"7","price":"$315.00"},
"3":{"Itemname":"yjk","unitprice":"76","Qty":"8","price":"$608.00"},
"4":{"Itemname":"hgj","unitprice":"4","Qty":"45","price":"$180.00"}
}';
$decodeJson = json_decode($json);
foreach($decodeJson as $key=>$val) {
print_r($val);
}
Live Json decode
Try that:
$json = json_decode($json);
foreach($json as $obj){
echo $obj->name;
.....
}
After some research, I found out that the most efficientt way that solves my problem here would be to do like the following.
$cash=json_decode($new_json, true);
echo $arr3[1]['Itemname'];
echo $arr3[1]['unitprice'];
:
:
and so on.
This can be put into loops easily, fetched into HTML text-fields (as I want here in this scenario) and so on.
I have a simple task that does not work
I Have a json file..
When you decode with the 'true' bool as second param, you will get an associative array back. In your code snippet you then loop it out.
What you should do, is skip the loop and just access the data from the assoc array right away:
echo $array['navn'];
// The JSON object:
{"nr":"5250","navn":"Odense SV","adresser":"http://oiorest.dk/danmark/postdistrikter/5250/adresser"}
// Is equivalent to this php assoc-array:
array("nr" => "5250", "navn" => "Odense SV", "adresser" => "http://oiorest.dk/danmark/postdistrikter/5250/adresser");
try following
<?php
$url = "http://oiorest.dk/danmark/postdistrikter/5000.json";
$content = file_get_contents($url);
$array = json_decode($content, true);
foreach ($array as $key=>$val) {
echo $val;
}
?>
This is my php code [EDITED]:
$redis_data = file_get_contents("http://example.org/data/data.txt");
That code returns the following json data:
{"Phone":"08XXXXX","StartTime":"121212","Customer":"Customer A","time":1407921302}
{"Phone":"08XXXXX0","StartTime":"111111","Customer":"Customer B","time":1407921302
{"Phone":"08XXXXX","StartTime":"131313","Customer":"Customer C","time":1407921302}
This is my code to looping parse the value:
$redis_data = file_get_contents("http://example.org/data/data.txt");
$redis_data = json_decode($redis_data, true);
foreach ($redis_data as $data) {
echo $data['Phone'];
echo "<br>";
}
But I got this errors:
Invalid argument supplied for foreach()
What am I doing wrong?
The data you trying to get is not well formatted json
[{"firstName":"John", "lastName":"Doe"},
{"firstName":"Anna", "lastName":"Smith"},
{"firstName":"Peter", "lastName": "Jones"}]
This is the json syntax.
and you are getting data in following format.
{"ANumber":"08122378673","BNumber":"500046","StartTime":"08122014102113","EndTime":"08122014104126","TrunkA":"S1JK2SBD1S","TrunkB":"N7JK2GSM1B","Customer":"PT.BNI","time":1407921302}
{"ANumber":"081351607600","BNumber":"14000","StartTime":"08122014102406","EndTime":"08122014103738","TrunkA":"S1JK2SSB1S","TrunkB":"EPJK2MNR0","Customer":"Bank Mandiri (CC_IB_Jasnita)","time":1407921302}
You may need to reformat your data string
You're trying to loop JSON - not PHP. You need to run json_decode (docs) on the your $redis_data variable before attempting to loop it.
$redis_data = json_decode($redis_data, true);
You need to decode the json before you can loop through it.
$redis_data = json_decode(file_get_contents("http://example.com/tes_files/data.txt"), true);
foreach ($redis_data as $data) {
echo $data['phone'];
}
Here is solution
$redis_data = explode( chr(10), file_get_contents("http://example.com/tes_redis/data.txt"));
foreach ($redis_data as $data) {
var_dump(json_decode($data));
$data = json_decode($data);
echo $data->Phone;
echo $data->StartTime;
echo $data->Customer;
//echo $data->ANumber;
//echo $data->BNumber;
}
you need to export data first.
first you have to convert json to array using json_decode function it will give array and after that you can loop
`
$jsonString =
'[{"Phone":"08XXXXX","StartTime":"121212","Customer":"Customer A","time":1407921302},
{"Phone":"08XXXXX0","StartTime":"111111","Customer":"Customer B","time":1407921302},
{"Phone":"08XXXXX","StartTime":"131313","Customer":"Customer C","time":1407921302} ]';
$array=json_decode($jsonString);
foreach ($arrayOfEmails as $data) {
echo $data->Phone."<br>";
}
`
I have the following problem. When i am trying to read some json data that are posted from an html page, i'm facing with the following error "Trying to get property of non-object on line".
Jquery script to create the json
var json = {"data":[]};
json.data.push({serialNumber: $serialNumber, xreosi: $xreosiToPost,
forma: $forma, apolia: $apolia});
Jquery for posting to php
$.post("page.php",{jsonData: JSON.stringify(json),
customer: $("#cusID").val()},function(data){});
PHP file
$json = json_decode($_POST['jsonData']);
foreach($json as $value){
$serialNumber = $value->serialNumber;
echo $serialNumber;
}
Thanks in advance.
Thereafter:
var json = {"data":[]};
json.data.push({serialNumber: $serialNumber, xreosi: $xreosiToPost,
forma: $forma, apolia: $apolia});
You have:
Object[data][0] = array('serialNumber' => ...);
Need:
$json = json_decode($_POST['jsonData'][0]);
or
$json = json_decode($_POST['jsonData']);
foreach($json as $row){
foreach($row as $value) {
$serialNumber = $value->serialNumber;
echo $serialNumber;
}
}
json_decode without second parameter returns result as php object. You have to pass true as second parameter. Also your data are in $json['data'], not $json:
$json = json_decode($_POST['jsonData'], true);
foreach($json['data'] as $value) {
$serialNumber = $value->serialNumber;
echo $serialNumber;
}
