I'm having problem with creating a foreach loop out of a JSON, I can't get the values out of the array correct, what am I doing wrong?
JSON:
[
{"Pages":{
"name":"Name 1",
"id":"3342939832994"
}
},
{"Pages":{
"name":"Name 2",
"id":"289051164453763"
}
}
]
PHP:
$json = $_POST['Publish'];
$json = $json->Pages
foreach($json as $key => $items) {
$id = $items->id;
$name = $items->id;
}
Do it like this
$json = json_decode($_POST['Publish']);
json_decode - Takes a JSON encoded string and converts it into a PHP variable.
You can use this code
<?php
$array = json_decode($_POST['Publish'], true);
foreach($array as $item) {
$id= $item['Pages']['id'];
$name = $item['Pages']['name'];
echo "id: $id <br/> name: $name <br/><br/>";
}
?>

$json='{
"status": true,
"data": {
"code": "44882S",
"quantity": 124740,
"amount": 124740,
"date": "2020-01-15"
}
}';
and I've made the code and the code doesn't work
$get = json_decode($json, true);
foreach ($get->data as $key) {
$code = $key->code;
$quantity = $key->quantity;
$amount = $key->amount;
$date = $key->date;
}
Is there something wrong with my code?
You requested json_decode to make the objects into arrays!
So either dont ask for the objects to be converted to an array
Also if you are looping over the object/array, you will get One entery per iteration and not all 4 at once.
$get = json_decode($json);
foreach ($get->data as $key=>$val) {
echo "$key = $val";
}
OR treat each value as an array value
$get = json_decode($json, true);
foreach ($get['data'] as $key=>$val) {
echo "$key = $val";
}
So here's the thing, I get this json from a url ( in my context i get it from a url, but let's say here I write my json in a variable :
$file = '[
{"status": "5.4.1","email": "dddddd#exelcia-it.com"},
{"status": "5.4.1",, "email": "sksksksk#exelcia-it.com"}
]'
Then I do $json = json_decode($file,true);
And I want to get all the emails so I do :
foreach ($json as $key => $value) {
echo $value["email"]. "<br>";
}
But what I also need, is to return something like that from the loop (only for one property):
"email = dddddd#exelcia-it.com".
So I need to also get the name of the property but I can't figure this out.
I tried
foreach($json as $key => $propName){
echo $key.'<br>';
}
But I just get the index (0,1,...), not what I want.
Thanks!
You have to loop each json row, this should works:
$file = '[{"status": "5.4.1","email": "dddddd#exelcia-it.com"},{"status": "5.4.1", "email": "sksksksk#exelcia-it.com"}]';
$json = json_decode($file,true);
foreach($json as $row)
{
foreach($row as $key => $value)
{
echo "<b>".$key."</b>".':'.$value.'<br>';
}
}
Use this loop to get key and value pairs together.
foreach($data as $row)
{
foreach($row as $key => $val)
{
echo $key . ': ' . $val;
echo '<br>';
}
}
Ok thanks that's what I needed !
For me I just need the email properties and values, so I do :
foreach($json as $row)
{
foreach($row as $key => $value)
{
if($key=='email'){
echo "<b>".$key."</b>".':'.$value.'<br>';
}
}
}
Awesome ! thanks !
`{
"student": [{
"name": "Alice",
"rno": "187654"
}]
}`
I am trying to get the value of rno using PHP code
`$data = json_decode($json, true);
foreach ($data as $item) {
$name = $item['name'] ;
$number= $item['rno'] ;
}`
#Sahil Gulati's code is more prefect and right way to parse the json in php
here is an other way to parse the json data in php
<?php
$data = json_decode($json, true);
foreach ($data as $item) {
foreach ($item as $val) {
echo $name = $val['name'];
echo $number = $val['rno'];
}
}
?>
the above code that i have shared you can understand easily. but after learning that how to parse json data in php you should use #Sahil Gulati's mathod.
Change this to:
foreach ($data as $item)
This:
foreach ($data["student"] as $item)
Try code snippet here
PHP code:
<?php
ini_set('display_errors', 1);
$data = json_decode($json, true);
foreach ($data["student"] as $item)
{
$name = $item['name'];
$number = $item['rno'];
}
You should take a closer look at the structure of the json encoded data. That helps to implement a clean iteration:
<?php
$input = <<<JSON
{
"student": [{
"name": "Alice",
"rno": "187654"
}]
}
JSON;
$data = json_decode($input);
$output = [];
array_walk($data->student, function($entry) use (&$output) {
$output[] = $entry->rno;
});
print_r($output);
The output of above code obviously is:
Array
(
[0] => 187654
)
The output format has been chosen as an array, since the json structure suggests that multiple students can be contained.
If you are only directly interested in the rno property of the first entry in the student array, then you can access it directly:
<?php
$input = <<<JSON
{
"student": [{
"name": "Alice",
"rno": "187654"
}]
}
JSON;
$data = json_decode($input);
var_dump($data->student[0]->rno);
The output of that variant obviously is:
string(6) "187654"
Im parsing json with php in this simple piece of code
<?php
$json = file_get_contents('list.json');
$data = json_decode($json,true);
$records=$data['records'];
foreach($records as $record)
{
echo $record['number']." ".$record['opened_at'];
}
?>
But i want to echo how many 'number' element are in my json file exemple bellow
{
"records":[
{
"number":"INC018****",
},
{
"number":"INC018****",
},
{
"number":"INC018****",
},
{
"number":"INC018****",
},
<?php
$json = file_get_contents('list.json');
$data = json_decode($json,true);
$records=$data['records'];
$numberCount = 0;
foreach($records as $record)
{
$numberCount += isset($record['number']); // Here we go
echo $record['number']." ".$record['opened_at'];
}
echo $numberCount;
?>
This function might be helpful: http://www.php.net/manual/en/function.array-count-values.php
$counts = array_count_values($records);
$numberCount = $counts['number'];
I have been trying to workout how to loop through and output the contents of a json file where field names start with "$" and keep getting an Undefined variable error message
Here is an example of the json file example (taken from https://mixpanel.com/help/reference/webhooks):
[
{
"$distinct_id":"13b20239a29335",
"$properties":{
"$region":"California",
"$email":"harry.q.bovik#andrew.cmu.edu",
"$last_name":"Bovik",
"$created":"2012-11-20T15:26:16",
"$country_code":"US",
"$first_name":"Harry",
"Referring Domain":"news.ycombinator.com",
"$city":"Los Angeles",
"Last Seen":"2012-11-20T15:26:17",
"Referring URL":"http://news.ycombinator.com/",
"$last_seen":"2012-11-20T15:26:19",
}
},
{
"$distinct_id":"13a00df8730412",
"$properties":{
"$region":"California",
"$email":"anna.lytics#mixpanel.com",
"$last_name":"Lytics",
"$created":"2012-11-20T15:25:38",
"$country_code":"US",
"$first_name":"Anna",
"Referring Domain":"www.quora.com",
"$city":"Mountain View",
"Last Seen":"2012-11-20T15:25:39",
"Referring URL":"http://www.quora.com/What-...",
"$last_seen":"2012-11-20T15:25:42",
}
}
]
I am testing with a static string just to try and get things working. Here is my test code...
<?php
$input = '[{"$distinct_id":"13b20239a29335","$properties":"dddd"}]';
$jsonObj = json_decode($input, true);
foreach ($jsonObj as $item) {
foreach ($item as $rec) {
echo '<br>';
$my_id = $rec->$distinct_id;
echo($my_id);
$my_id = $rec->$properties;
echo($my_id);
}
echo '<br>';
}
?>
Any help would be appreciated.
Noob!
UPDATE: Musa gave this example which works for the single level json:
foreach ($jsonObj as $item) {
echo '<br>';
$my_id = $item->{'$distinct_id'};
echo($my_id);
$my_id = $item->{'$properties'};
echo($my_id);
echo '<br>';
}
How can this then be adapted to read and output all elements of the bigger multi-level json file?
Use Curly bracket notation
$object->{'$property'};
Edit
foreach ($jsonObj as $item) {
echo '<br>';
$my_id = $item->{'$distinct_id'};
echo($my_id);
foreach ($item->{'$properties'} as $my_prop => $value){
echo("$my_prop => $value");
}
echo '<br>';
}

With the nested loop you're iterating the properties $distinct_id and $properties so $rec is actually a string and not an object.
Also your json is invalid as it has trailing , in the $properties field.
