My database(mysql)
product_name
ID product_name qty
1 item a 5
2 item b 4
3 item c 3
My php code
<?php
include("connect.php");
$query="select*from product_name";
$result = mysqli_query($db, $query) or die("Error in Selecting " .mysqli_error($db));
while ($row=mysqli_fetch_assoc($result)){
$arrey[]=$row;
}
echo json_encode($arrey);
?>
Output is
[{
"id": "1",
"productname": "item a",
"qty": "5"
}, {
"id": "2",
"productname": "item b",
"qty": "4"
}, {
"id": "3",
"productname": "item c",
"qty": "3"
}]
I have to face data like bellow
{
"status": "true",
"message": "Data fetched successfully!",
"data": [{
"id": "1",
"productname": "item a",
"qty": "5"
},
{
"id": "2",
"productname": "item b",
"qty": "4"
},
{
"id": "3",
"productname": "item c",
"qty": "3"
}
]
}
How to do it?
You should add your array in an header array
$myArray = ['status' =>"true",
"message"=> "Data fetched successfully!",
'data' =>$arrey];
.
<?php
include("connect.php");
$query="select*from product_name";
$result = mysqli_query($db, $query) or die("Error in Selecting " .mysqli_error($db));
while ($row=mysqli_fetch_assoc($result)){
$arrey[]=$row;
}
$myArray = ['status' =>"true",
"message"=> "Data fetched successfully!",
'data' =>$arrey];
echo json_encode($myArray);
?>

I have a JSON object in PHP Like
$my_json = '[{
"No": "1",
"Id": "10",
"msg": "Value is 10"
},
{
"No": "2",
"Id": "55",
"msg": "value is 55"
}, {
"No": "3",
"Id": "38",
"msg": "value is 38 "
}, {
"No": "4",
"Id": "95",
"msg": "value is 95 "
} ]';
I have converted it to PHP object array using $obj_arr= json_decode($my_json);
Now, based on user selection I want to filter array element
Eg. if the user selects "ID" as 38 and 55 then new array should note have ID 10 and 95 IN it and must contain all other data related to those ID just like an original one
EG
$final_json = '[
{
"No": "2",
"Id": "55",
"msg": "value is 55"
}, {
"No": "3",
"Id": "38",
"msg": "value is 38 "
} ]';
Try this:
<?php
$my_json = '[{
"No": "1",
"Id": "10",
"msg": "Value is 10"
},
{
"No": "2",
"Id": "55",
"msg": "value is 55"
}, {
"No": "3",
"Id": "38",
"msg": "value is 38 "
}, {
"No": "4",
"Id": "95",
"msg": "value is 95 "
} ]';
$selected = [38, 55];
$obj = json_decode($my_json);
$result = array_filter($obj, function($row) use ($selected) {
return in_array($row->Id, $selected);
});
echo json_encode(array_values($result), JSON_PRETTY_PRINT);
Output:
[
{
"No": "2",
"Id": "55",
"msg": "value is 55"
},
{
"No": "3",
"Id": "38",
"msg": "value is 38 "
}
]
If you want to filter out the selected values above instead of keep them, return the negation of in_array.
Below is json code where i have o display its values. How to fetch the output as given below
$jsondata = '{
"flowers": [
{
"id": "1",
"name": "Le Grand Bouquet Blanc",
"price": "65",
"currency": "euro"
},
{
"id": "2",
"name": "Roses",
"price": "33",
"currency": "euro"
},
{
"id": "3",
"name": "Mandarine",
"price": "125",
"currency": "euro"
}
]
}';
Output should come like this
Name : Le Grand Bouquet Blanc, Price : 65
Name : Roses, Price : 33
Name : Mandarine, Price : 125
Total: 223 Euro
Any Help?
JSON decode, loop through the data and output the required text like so:
$data = json_decode($jsondata);
$total = 0;
foreach($data->flowers as &$datum) {
printf('Name : %s, Price: %d'.PHP_EOL, $datum->name, $datum->price);
$total += $datum->price;
}
printf('Total: %d Euro'.PHP_EOL, $total);
Read up on some basic PHP functions/concepts:
http://php.net/manual/en/function.json-decode.php
http://php.net/manual/en/control-structures.foreach.php
http://php.net/manual/en/function.printf.php
http://php.net/manual/en/function.echo.php
http://php.net/manual/en/language.operators.arithmetic.php
Try using json_decode() with true as second attribute to convert JSON it into array first.Then use foreach loop and get desired result.
<?php
$jsondata = '{
"flowers": [
{
"id": "1",
"name": "Le Grand Bouquet Blanc",
"price": "65",
"currency": "euro"
},
{
"id": "2",
"name": "Roses",
"price": "33",
"currency": "euro"
},
{
"id": "3",
"name": "Mandarine",
"price": "125",
"currency": "euro"
}
]
}';
$array = json_decode($jsondata,true);
//print_r($array);
$sum = 0;
foreach($array['flowers'] as $flowers)
{
echo "Name : ".$flowers['name'].",Price : ".$flowers['price'].PHP_EOL;
$sum+=$flowers['price'];
$currency = $flowers['currency'];
}
echo "Total:".$sum." ".$currency;
Try this.
$jsondata = '{
"flowers": [
{
"id": "1",
"name": "Le Grand Bouquet Blanc",
"price": "65",
"currency": "euro"
},
{
"id": "2",
"name": "Roses",
"price": "33",
"currency": "euro"
},
{
"id": "3",
"name": "Mandarine",
"price": "125",
"currency": "euro"
}
]
}';
$data = json_decode($jsondata,true);
echo "Name : " . $data['flowers'][0]['name'] . ' , Price: ' . $data['flowers'][0]['price'] ;
Below is my JSON file:
{
"example": "1",
"example2": 2,
"text": "3",
"info": {
"agent": 4,
"sum": 5,
"collection": [{
"Name": "6",
"Pic": "7"
} {
"Name": "8",
"Pic": "9"
}, {
"Name": "10",
"Pic": "11"
}]
}
}
How would I display each 'name' and 'pic' I think I need to use a foreach loop but don't know how to.
This is all the code I have:
$data = json_decode(file_get_contents('http://linktojson.com'));
echo $data['info']['collection'][0]['Name'];
echo $data['info']['collection'][0]['Pic'];
This should work
$data = json_decode(file_get_contents('http://linktojson.com'));
echo "<pre>".print_r($data,1)."</pre>";
foreach($data->info->collection as $key){
echo $key->Pic;
echo $key->Name;
}
Valid JSON
{
"example": "1",
"example2": 2,
"text": "3",
"info": {
"agent": 4,
"sum": 5,
"collection": [{
"Name": "6",
"Pic": "7"
}, {
"Name": "8",
"Pic": "9"
}, {
"Name": "10",
"Pic": "11"
}]
}
}
I get details from the user through HTML form, and onclick the form submission, I run the php file, save2json.php, which retrieves from HTML form, and posts it as JSON in the file appointments.json.
save2json.php
$formdata = array(
$_POST['doctor'] => array(
'name'=> $_POST['name'],
'phone'=> $_POST['phone'],
'bday'=> $_POST['bday'],
'datepicker'=> $_POST['datepicker'],
)
);
$filetxt = 'appointments.json';
$arr_data = array();
if(file_exists($filetxt))
{
$jsondata = file_get_contents($filetxt);
$arr_data = json_decode($jsondata, true);
}
$arr_data[] = $formdata;
$jsondata = json_encode($arr_data, JSON_PRETTY_PRINT);
if(file_put_contents('appointments.json', $jsondata))
What I get: [appointments.json]
[{
"Doctor #3": {
"name": "0",
"phone": "0",
"bday": "0",
"datepicker": "0"
}
}, {
"Doctor #3": {
"name": "1",
"phone": "1",
"bday": "1",
"datepicker": "1"
}
}, {
"Doctor #1": {
"name": "2",
"phone": "2",
"bday": "2",
"datepicker": "2"
}
}, {
"Doctor #2": {
"name": "3",
"phone": "3",
"bday": "3",
"datepicker": "3"
}
}]
What I want: [appointments.json]
[{
"Doctor #3": [{
"name": "0",
"phone": "0",
"bday": "0",
"datepicker": "0"
},
{
"name": "1",
"phone": "1",
"bday": "1",
"datepicker": "1"
}
],
"Doctor #1": {
"name": "2",
"phone": "2",
"bday": "2",
"datepicker": "2"
},
"Doctor #2": {
"name": "3",
"phone": "3",

}
}]
If it is under same doctor, I want to make both objects come under the same array. And if it isn't like Doctor 1 and Doctor 2, in this case, I want them as separate apart from Doctor 3 array.
Thanks in Advance :)
This is the first attempt to put it inside the doctor array key:
<?php
// build the array
$docDetails = array(
'name'=> $_POST['name'],
'phone'=> $_POST['phone'],
'bday'=> $_POST['bday'],
'datepicker'=> $_POST['datepicker'],
);
// get the file's content as an array.
$filetxt = 'appointments.json';
if(file_exists($filetxt))
$arr_data = json_decode(file_get_contents($filetxt), true);
else
$arr_data = array();
$arr_data[$_POST['doctor']][] = $docDetails;
?>
I am building an admin backend for an android app. My code provides a json output which the android developer then uses in his app. The developer asked me if it is possible to reduce the hierarchy level in the json output
as in remove the highlighted []0 and put the contents directly inside the []data instead.
This is my current php code
if($type == 1 ) //Handle item display
{
try
{
$query = "SELECT category FROM category";
$result= $DBH->query($query);
while($row = $result->fetch(PDO::FETCH_ASSOC))
{
$cat = $row['category'];
$query1 = "SELECT * FROM item WHERE catagory='$cat'";
$value = $DBH->query($query1);
if($row1 = $value->fetchAll(PDO::FETCH_OBJ)){
$main[] = array('data'=>array($row1));
}
else
{
$main[] = array('data'=>array('catagory'=>$row['category']));
}
}
echo json_encode($main);
$result->closeCursor(); //Close database connection free resources
$DBH = null;
}
catch(PDOException $e){
print $e->getMessage ();
die();
}
}
And the json output being generated
[
{
"data": [
[
{
"id": "2",
"name": "rice",
"price": "20",
"description": "Plain Rice",
"image": "4106_rice.jpg",
"time": "12 mins",
"catagory": "Lunch",
"subcat": ""
},
{
"id": "3",
"name": "item 1",
"price": "32",
"description": "item 1 description",
"image": "1370_2Ckjikljklkljh.jpg",
"time": "10",
"catagory": "Lunch",
"subcat": "Chicken Soup"
},
{
"id": "4",
"name": "hello",
"price": "10",
"description": "fgsdjfsfsdj",
"image": "",
"time": "76",
"catagory": "Lunch",
"subcat": ""
}
]
]
},
{
"data": {
"catagory": "Dinner"
}
},
{
"data": {
"catagory": "Soup"
}
},
{
"data": {
"catagory": "Test"
}
}
]
I am not very sure if I can make the changes he asked or if it is possible. Is it doable?
Your json structure is inconsistent and try this approach, will be easier for the developer to parse
