PHP split a string and insert in MySQL - php

Question

I am using AJAX to send an array of values to a PHP page that will insert the data into MySQL database. The problem is that I am not sure how to split the data into 5 different veriables and loop to insert into DB.
AJAX Request:
Array:
[".testimonial", 1119, 316, 1663, 608, "#header", 723, 66, 1663, 608]
Posting the array:
Sending Array Parameters using " ; " to split.
clicks
.testimonial;1119;316;1663;608;#header;723;66;1663;608

clicks=.testimonial%3B1119%3B316%3B1663%3B608%3B%23header%3B723%3B66%3B1663%3B608
PHP Page
<?php
$clicks = $_GET["clicks"];
$clickArray = explode(";",$clicks);
$arrays = array_chunk($clickArray, 5);
foreach ($arrays as $array_num => $array) {
foreach ($array as $item_num => $item) {
echo "". $item . "<br/>";
}
}
$servername = "localhost";
$username = "root";
$password = "password";
$dbname = "clickmap";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "INSERT INTO data (user_id, identifier_name, pos_x, pos_y, window_width, window_height, status)
VALUES ('1', '$postIdentifier', '$postPos_x', '$postPos_y','$postWindowWidth','$postWindowHeight', 'ok')";
if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
?>
Current PHP Result:
.testimonial
1119
316
1663
608
#header
723
66
1663
608
New record created successfully

This should work, but using extract is usually not recommended as it can easily lead to bugs that are hard to debug.
$keys = array('postIdentifier', 'postPos_x', 'postPos_y','postWindowWidth','postWindowHeight');
foreach ($arrays as $array_num => $array) {
$values = array();
foreach ($array as $item_num => $item) {
$values[] = $item;
}
$data = array_combine($keys, $values);
extract($data); // now your variables are declared with the right values http://php.net/manual/en/function.extract.php
// .. run SQL insert here
}
