Using Highcharts with mysql for Page Visits - php

Question

I am trying to use Highcharts to display user visits per property, however I am unsure how to set up the SQL query to properly display this. It would be a lot easier if our database simply listed page visits during specific periods of time, but it's stored per-user, per-property, per visit, as you can see here:
I know that I have to query the sum visits per property and sort it by month, but exactly the best way to do this is beyond me. This what I've got so far:
<?php
$con = mysql_connect('localhost', 'root', 'root');
if (!$con) {
die('Could not connect: '.mysql_error());
}
mysql_select_db('demeure', $con);
//$date_start = $_POST['date_start'];
//$date_end = $_POST['date_end'];
$date_start = '2012-07-01 00:00:00';
$date_end = '2012-08-01 00:00:00';
$result = mysql_query("
SELECT
COUNT(id) AS count,
created_at
FROM
user_property_visits
WHERE
created_at BETWEEN '$date_start' AND '$date_end'");
while ($row = mysql_fetch_array($result)) {
echo $row['count'] . "\t" . $row['created_at']. "\n";
}
mysql_close($con);
?>
This results with a blank page. I'm not sure how close I am to getting what I need, but thanks for the help.

I'm not sure if you want this, but you can filter the period in the WHERE clause. Check if it could help:
<?php
// Show all PHP errors.
error_reporting(E_ALL);
// Connect with MySQL
$con = mysql_connect('localhost', 'your_user', 'your_password');
if (!$con) {
die('Could not connect: '.mysql_error());
}
mysql_select_db('demeure', $con);
// Obtain date range from $_POST or
// manually edit this.
//$date_start = $_POST['date_start'];
//$date_end = $_POST['date_end'];
$date_start = '2012-07-20 20:30:00';
$date_end = '2012-07-20 20:37:00';
// Query with GROUP BY
$result = mysql_query("
SELECT
COUNT(id) AS `count`,
created_at
FROM
user_property_visits
WHERE
created_at BETWEEN '$date_start' AND '$date_end'
GROUP BY
created_at");
while ($row = mysql_fetch_array($result)) {
echo 'Count: ' . $row['count'] . '<br/>' . 'Group by date: ' . $row['created_at'] . '<br/>';
}
// With the schema used in SQL Fiddle, this code will reproduce
//
// A PHP Error was encountered
// Severity: 8192
// Message: mysql_connect(): The mysql extension is deprecated and
// will be removed in the future: use mysqli or PDO instead
//
// Filename: views/home.php
//
// Line Number: 7
//
// Count: 4
// Group by date: 2012-07-20 20:36:28
mysql_close($con);
?>
Using this, you can use a datepicker, for example, to select the date range and obtain this values via POST (ajax).

I was able to solve it with the following:
<?php
$host = "localhost";
$user = "root";
$pass = "root";
$database = "demeure_new";
$dsn = "mysql:dbname=$database;host=$host";
$pdo = new PDO($dsn, $user, $pass);
$query = "SELECT DAY(created_at) AS day, MONTH(created_at) AS month, YEAR(created_at) AS year, count(user_id) AS count FROM user_property_views GROUP BY day";
$stmt = $pdo->prepare($query);
$stmt->execute();
$result = $stmt->fetchAll(PDO::FETCH_ASSOC);
$stmt->closeCursor();
$newArray = array();
foreach($result as $r)
$newArray[$r["year"]][$r["month"]][$r["day"]] = $r["count"];
//print_r($newArray);
json_encode($result, JSON_NUMERIC_CHECK);
echo json_encode($newArray);
?>
