Two queries mysql in one object json - php

Question

I have two tables that I want to convert them to json like this:
[
{
"date":"2013-07-20",
"id":"123456",
"year":"2013",
"people":[
{
"name":"First",
"age":"60",
"city":"1"
},
{
"name":"second",
"age":"40",
"city":"2"
},
{
"name":"third",
"age":"36",
"city":"1"
}
]
}
]
but the result of my code is this:
[
{
"date":"2013-07-20",
"id":"123456",
"year":"2013",}
,{
"people":[
{
"name":"First",
"age":"60",
"city":"1"
},
{
"name":"second",
"age":"40",
"city":"2"
},
{
"name":"third",
"age":"36",
"city":"1"
}
]
}
]
the code creates a new object to the array "people" and I want that are in the same object
$result = mysql_query("SELECT * FROM data where id='123456'");
$fetch = mysql_query("SELECT name,age,city FROM people where id='123456'");
$json = array();
$json2['people'] = array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)){
$json[] = $row;
}
while ($row = mysql_fetch_assoc($fetch)){
$row_temp["name"]=$row["name"];
$row_temp["age"] = $row["age"];
$row_temp["city"] = $row["city"];
array_push($json2['people'],$row_temp);
}
array_push($json, $json2);
echo Json_encode($json);
How I can make the array is in the same object as the table "data"?
Many thanks

I think you may try this
$result = mysql_query("SELECT * FROM data where id='123456'");
$fetch = mysql_query("SELECT name,age,city FROM people where id='123456'");
// I think, you'll get a single row, so no need to loop
$json = mysql_fetch_array($result, MYSQL_ASSOC);
$json2 = array();
while ($row = mysql_fetch_assoc($fetch)){
$json2[] = array(
'name' => $row["name"],
'age' => $row["age"],
'city' => $row["city"]
);
}
$json['people'] = $json2;
echo json_encode($json);
Result of print_r($json) should be something like this
Array
(
[date] => 2013-07-20
[year] => 2013
[id] => 123456
[people] => Array
(
[0] => Array
(
[name] => First
[age] => 60
[city] => 1
)
[1] => Array
(
[name] => second
[age] => 40
[city] => 2
)
)
)
Result of echo json_encode($json) should be
{
"date" : "2013-07-20",
"year":"2013",
"id":"123456",
"people":
[
{
"name" : "First",
"age" : "60",
"city" : "1"
},
{
"name" : "second",
"age" : "40",
"city" : "2"
}
]
}
If you do echo json_encode(array($json)) then you will get your whole json wrapped in an array, something like this
[
{
"date" : "2013-07-20",
"year":"2013",
"id":"123456",
"people":
[
{
"name" : "First",
"age" : "60",
"city" : "1"
},
{
"name" : "second",
"age" : "40",
"city" : "2"
}
]
}
]

You were very close, but you want the People array to be a direct value of the outer array and you've wrapped it in an extra array.
Also, please note that the MySQL library you are using is deprecated. That means it will be removed from PHP in a future release. You should replace calls from the MySQL_* family of functions with either mysqli or pdo
$result = mysql_query("SELECT * FROM data where id='123456'");
$fetch = mysql_query("SELECT name,age,city FROM people where id='123456'");
$json = array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)){
$json[] = $row;
}
$json['people'] = array();
while ($row = mysql_fetch_assoc($fetch)){
$row_temp["name"]=$row["name"];
$row_temp["age"] = $row["age"];
$row_temp["city"] = $row["city"];
array_push($json['people'],$row_temp);
}
echo Json_encode($json);

You can make it work by waiting to use the key people until the very end when you join the two arrays. Up until then, just load the data into $json and $json2.
$json = array('date' => '2013', 'id' => '123456', 'year' => '2013');
$result = mysql_query("SELECT * FROM data where id='123456'");
$fetch = mysql_query("SELECT name,age,city FROM people where id='123456'");
$json = array();
$json2 = array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)){
$json[] = $row;
}
while ($row = mysql_fetch_assoc($fetch)){
$row_temp["name"]=$row["name"];
$row_temp["age"] = $row["age"];
$row_temp["city"] = $row["city"];
array_push($json2, $row_temp);
}
$json['people'] = $json2;
echo Json_encode($json);
