To set up an API endpoint using PHP and mySQL to receive iOT data, follow these steps:

Suggested Read – What are APIs and how do APIs work?

Set up your web server 

Create mySQL database 

Create a PHP script to handle incoming data

Create a PHP script that will handle the incoming iOT data and store it in the mySQL database. Here’s an example script that accepts POST requests and inserts the data into a mySQL database:

<?php$servername = “localhost”;
$username = “yourusername”;
$password = “yourpassword”;
$dbname = “yourdatabase”;// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);// Check connection
if ($conn->connect_error) {
die(“Connection failed: ” . $conn->connect_error);
}// Get the POST data
$data = file_get_contents(‘php://input’);
$data = json_decode($data, true);// Insert data into mySQL database
$sql = “INSERT INTO iot_data (timestamp, temperature, humidity)
VALUES (’{$data[‘timestamp’]}‘, ’{$data[‘temperature’]}‘, ’{$data[‘humidity’]}’)“;if ($conn->query($sql) === TRUE) {
echo “Data inserted successfully”;
} else {
echo “Error: ” . $sql . “<br>” . $conn->error;
}$conn->close();
?>

Set up the API endpoint

This code checks if the request method is POST and includes the iot.php script if it is.

Send data to the API endpoint

Here’s an example cURL command:

curl –location –request POST ‘https://yourdomain.com/api/iot’ \
–header ‘Content-Type: application/json’ \
–data-raw ‘{
    “timestamp”: “2022-03-30 13:00:00″,
    “temperature”: 25,
    “humidity”: 60
}’

This command sends a POST request to the https://yourdomain.com/api/iot endpoint with JSON data containing a timestamp, temperature, and humidity.

In conclusion…

In summary, to set up an API endpoint using PHP and mySQL to receive iOT data, you need to create a mySQL database, create a PHP script to handle incoming data, define a route to access the script, and send data to the API endpoint using a tool such as Postman or cURL. By following these steps, you can create an API endpoint that receives iOT data and stores it in a mySQL database.
