php with Nested JSON - php

Question

These Items should be put together into a JSON variable, including shop details:
{
"Name": "Shop 1",
"Time": "2015-12-01 12:50",
"Items": [
{
"Name": "Item-1",
"Count": "4",
"Charge": "100"
},
{
"Name": "Item-3",
"Count": "4",
"Charge": "100"
}
],
"Total": "800"
}
To get the outer JSON part I use:
class PrintData {
public $Name = "";
public $Time = "";
// ??
public $Total = "";
}
$printdata = new PrintData();
$printdata->Name=$shop_name;
$printdata->Time=$os_tsready;
// ?? $printdata->Item=$printitems;
$printdata->Total=1007;
However, I cannot figure out how I can get the two Item lines into JSON.
foreach($orderrecords as $or) {
$o_name=escape($or->o_name);
$o_cout=escape($or->o_count);
$o_charge=escape($or->o_charge);
How can I add the Item records correctly?

Answer 1

Fully OOP approach:
class Item {
public $Name;
public $Count;
public $Charge;
public function __construct($name, $count, $charge) {
$this->Name = $name;
$this->Count = $count;
$this->Charge = $charge;
}
}
class PrintData {
public $Items;
public $Name;
public $Time;
public $Total;
public function __construct($name, $time, $items, $total) {
$this->Name = $name;
$this->Time = $time;
$this->Total = $total;
$this->Items = $items;
}
}
$res = new PrintData(
"Shop 1",
"2015-12-01 12:50",
array(
new Item("Item-1", "4", "100"),
new Item("Item-3", "4", "100"),
),
"800"
);
echo json_encode($res);

Answer 2

Try this:
class PrintData {
public $Name = "";
public $Time = "";
public $Items = [];
public $Total = "";
}
$printdata = new PrintData();
$printdata->Name=$shop_name;
$printdata->Time=$os_tsready;
$printdata->Items=$printitems;
$printdata->Total=1007;
Where $printitems is an array of $item elements (like below)
And individually,
$item = array(
"Name" => "Item-1",
"Count" => "4",
"Charge" => "100"
);
$printdata->Items[0] = $item;

Answer 3

$printitems should be an array here.
$printitems = array(
array('Name' => 'Item-1', 'Count' => '4', 'Charge' => '100'),
array('Name' => 'Item-3', 'Count' => '4', 'Charge' => '100')
);
Final Code
<?php
class PrintData {
public $Name = "";
public $Time = "";
// ??
public $Total = "";
}
$printdata = new PrintData();
$printdata->Name= 'Shop 1';
$printdata->Time='2015-12-01 12:50';
// ?? $printdata->Item=$printitems;
$printdata->Total='800';
$printitems = array(
array('Name' => 'Item-1', 'Count' => '4', 'Charge' => '100'),
array('Name' => 'Item-3', 'Count' => '4', 'Charge' => '100')
);
$printdata->Item = $printitems;
echo '<pre>';
// TILL NOW $printdata is an Object
// json_encode() converts $printdata into JSON Object
print_r(json_encode($printdata)); // THIS WILL GIVE YOUR DESIRED RESULT
