JSON giving weird output in php - php

Question

I'm learning php as well as JSON and can't figure out why I have following output:
JSON RESULT:
{
"Results": [
{
"user_id": "1"
},
{
"email": "user#example.com"
},
{
"first_name": "User"
},
{
"last_name": "One"
},
{
"password": "pass1"
},
{
"creation_date": null
},
{
"profile_type": "0"
},
{
"user_id": "2"
},
{
"email": "user2#example.com"
},
{
"first_name": "User"
},
{
"last_name": "Two"
},
{
"password": "pass2"
},
{
"creation_date": null
},
{
"profile_type": "0"
}
]
}
PHP:
<?php
require_once 'config/db.php';
$sql = new db();
$conn = $sql->connect();
$query = isset($_GET['query']) ? mysql_real_escape_string($_GET['query']) : "";
if(!empty($query))
{
$qur = mysql_query($query);
$result = array();
while($r = mysql_fetch_assoc($qur))
{
extract($r);
foreach($r as $key => $value)
{
$result[] = array($key => $value);
}
$json = array("Results" => $result);
}
}
#mysql_close($conn);
/* Output header */
header('Content-type: application/json');
echo json_encode($json, JSON_PRETTY_PRINT);
?>
My question is, why does it split each value into new record, I want each MySQL record to be one JSON record.

Answer 1

Just assign your row to $result:
while($r = mysql_fetch_assoc($qur))
{
$result[] = $r;
}
$json = array("Results" => $result);

Answer 2

It's doing this because of your for loop:
foreach($r as $key => $value)
{
$result[] = array($key => $value);
}
Maybe you should try something like json_encode on the data returned.
http://php.net/manual/en/function.json-encode.php
EDIT:
Try something like this:
$data = array();
while($row = mysqli_fetch_assoc($result))
{
$data[] = $row;
}
echo json_encode($data, JSON_PRETTY_PRINT);

Answer 3

I wouldn't use mysql to start with, use PDO. But if you must, you don't need foreach. Below will do.
while($r = mysqli_fetch_assoc($qur))
{
$result[] = $r;
$json = array("Results" => $result);
}
