This is my JSON file(database.json):
{
"doctors": [
{
"ID": "ahmadakhavan",
"pass": "1234",
"name": "Ahmad Akhavan",
"profilePic": "address",
},
{
"ID": "akramparand",
"pass": "1234",
"name": "Akram Parand",
"profilePic": "address",
}
],
"games": [
{
"ID": "shuttlefuel_1",
"locked": "0",
"logo": "gameLogo",
},
{
"ID": "birthdaycake",
"locked": "0",
"logo": "gameLogo",
}
],
"users": [
{
"ID": "alirezapir",
"prescribes": [
{
"doctorName": "doctor1",
"done": "yes",
"gameId": "wordschain"
},
{
"doctorName": "doctor2",
"done": "no",
"gameId": "numberlab"
}
],
"profilePic": "address"
},
{
"ID": "amirdibaei",
"pass": "1234",
"profilePic": "address"
}
]
}
I want to add a child under prescribes array for a specific ID.
Below is what I have done in my PHP code to do this:
<?php
$username = $_REQUEST['name'];
$data = $_REQUEST['data'];
//Load the file
$contents = file_get_contents('./database.json');
$arraydata = json_decode($data,true);
//Decode the JSON data into a PHP array.
$contentsDecoded = json_decode($contents, true );
foreach($contentsDecoded['users'] as $item){
if($item['ID'] == $username){
if(!isset($item['prescribes'])){
$item['prescribes'] = Array();
}
array_push($item['prescribes'],$arraydata);
$json = json_encode($contentsDecoded, JSON_UNESCAPED_UNICODE );
file_put_contents('./database.json', $json);
exit('1');
exit;
}
}
exit('0');
exit;
?>
If I echo $item['prescribes'] after the line array_push($item['prescribes'],$arraydata); I see data added to it, but the original file (database.json) won't show new added data.
(meaning that this new data is not added to $contentsDecoded)
You have to change foreach() code like below:-
foreach($contentsDecoded['users'] as &$item){ //& used as call by reference
if($item['ID'] == $username){
$item['prescribes'][] = $arraydata; //assign new value directly
$json = json_encode($contentsDecoded, JSON_UNESCAPED_UNICODE );
file_put_contents('./database.json', $json);
exit;
}
}
Change your foreach to change the $contentsDecoded array:
foreach($contentsDecoded['users'] as $key => $item){
if($item['ID'] == $username){
if(!isset($item['prescribes'])){
$contentsDecoded['users'][$key]['prescribes'] = Array();
}
array_push($contentsDecoded['users'][$key]['prescribes'],$arraydata);
$json = json_encode($contentsDecoded, JSON_UNESCAPED_UNICODE );
file_put_contents('./database.json', $json);
exit('1');
exit;
}
}
This is the JSON

I already try with this code
$json = json_decode($url, true);
foreach($json as $value)
{
$_id = $value->_id;
}
it didn't work. Please help, I need to get the value to show them on the view. Did I do this wrong? this json is difficult because i didn't understand the structure.
I usually decode json with format
[{"id":"1","name":"faisal"}]
like this and with my foreach it's working.
If the second parameter of json_decode is true, the function will return an array instead of an object. Also, you would need to loop over the circuit_list property of the object.
$json = json_decode($url); // <- remove the parameter
foreach($json->circuit_list as $value) // <- loop over circuit_list
{
$_id = $value->_id;
}
<?php
$json = json_decode($url,true);
foreach($json['circuit_list'] as $value)
{
$id = $value['_id'];
}
?>
Here's my JSON file:
{
"user": {
"id": "2.8.388387",
"category": "posts",
"json_metadata": {
"tags": [
"new",
],
"image": [
"https://s32.postimg.org/4twcn4yrp/13918652_1345543288792650_1255274463_o.gif"
]
}
}
}
And PHP:
$json = json_decode($content, true);
foreach($json as $i){
$id = $i['id'];
$category = $i['category'];
$image = $i['json_metadata']['image'];
echo $id;
echo $category;
echo $image;
}
Echo $id and $category works just fine. However, $image errors:
Warning: Illegal string offset 'image'
Any ideas what do I miss?
json_metadata is array within loop, so you just need to get data from array as we do in array. it's simple...This will work now foreach loop. you can also print json_metadata array in loop.
$content = '{
"user": {
"id": "example glossary",
"category": "example glossary",
"json_metadata": {
"tags": ["new"],
"image": [
"https://s32.postimg.org/4twcn4yrp/13918652_1345543288792650_1255274463_o.gif"
]
}
}
}';
$json = json_decode($content, true);
foreach ($json as $i) {
$id = $i['id'];
$category = $i['category'];
$image = $i['json_metadata']['image'][0];
echo $id;
echo $category;
echo $image;
}
Try this code
$content = '{
"user": {
"id": "example glossary",
"category": "example glossary",
"json_metadata": {
"tags": ["new"],
"image": [
"https://s32.postimg.org/4twcn4yrp/13918652_1345543288792650_1255274463_o.gif"
]
}
}
}';
$json = json_decode($content, true);
print_r($json['user']['json_metadata']['image'][0]);
You will got:
https://s32.postimg.org/4twcn4yrp/13918652_1345543288792650_1255274463_o.gif
I have a json file like this
{
"id": "123456789012345",
"members": {
"data": [
{
"name": "Dylan John",
"administrator": false,
"id": "12341234"
},
{
"name": "Test user",
"administrator": false,
"id": "43214321"
},
{
"name": "Demo user",
"administrator": false,
"id": "55445544"
},
{
"name": "Fake user",
"administrator": false,
"id": "11991199"
}
],
"paging": {
"next": "www.123456demo12345.com"
}
}
}
I need to extract the id of each name.
I just start my php code like that but simply display only the master id:
<?php
$url = "http://www.1234demo1234fake.com/user.json";
$json = file_get_contents($url);
$data = json_decode($json, TRUE);
echo $data[id]; //echo master id
echo $data[members][data][id];
?>
You have to iterate over $data['members']['data'] and print $data['members']['data'][$i]['id'].
Your JSON object contains property members again members has property data.
Now data is an array.
Just loop over data, you get array of objects (members), fetch property id from it.
<?php
$abc = json_decode($your_json_sting);
$membersData = $abc->members->data;
$memberIds = array();
foreach ($membersData as $mem) {
$memberIds[] = $mem->id;
}
echo '<pre>';print_r($memberIds);echo '</pre>';
?>
Can any one tell me how to extract the 'honda' value out of the array below using php?
{
"version": "1.0",
"encoding": "UTF-8",
"entry": {
"name": "bob",
"car": {
"model": "honda"
}
}
}
This looks like a json encoded object. What you could do is:
$info = json_decode($data, true); //where $data has your stuff from the question
$carModel = $obj['entry']['car']['model'];
If you have all that in a variable called "obj", then
$obj = '{ "version": "1.0", "encoding": "UTF-8", "entry": { "name": "bob", "car": { "model": "honda" } } }';
$arr = json_decode($obj, true);
echo $arr['entry']['car']['model'];
should be 'honda'
EDITED: Per Omar below, you do need the true as the second param in json_decode. He should get selected as the correct answer.
Use json_decode as: http://php.net/manual/fr/function.json-decode.php
<?php
$json = '{"version": "1.0","encoding": "UTF-8","entry": {"name": "bob","car": {"model": "honda"} } }';
$tab = json_decode($json, true);
$honda = $tab['entry']['car']['model'];
var_dump($honda);
// or with object:
$obj = json_decode($json);
$honda = $obj->entry->car->model;
var_dump($honda);
