HTML: We create the structure of our web page where we'll place the elements that interact with Ajax.
PHP Script: This is where we process the Ajax requests on the server side using PHP. Depending on the type of request (GET or POST), we can access data sent by the client, perform actions, query a database, or generate responses.
Server-Side Processing: The PHP script on the server receives the Ajax request, processes it, and generates a response.
Response: The server sends the response back to us. This could be in various formats, such as JSON, XML, HTML, or plain text, depending on what our application needs.
Client-Side Error Handling: We need to handle potential errors that might occur during the Ajax request, such as network issues or server errors. This ensures that our application provides a smooth user experience even in case of failures.
Server-Side Error Handling: Within our PHP script, we should include error handling mechanisms to catch and handle any issues that might arise during processing.
Cross-Site Scripting (XSS) Protection: We sanitize and validate data coming from the client side to prevent malicious code injection.
CSRF Protection: We implement measures to prevent Cross-Site Request Forgery attacks by including and verifying tokens in our requests.
Integration with Databases:
If our application requires data retrieval or manipulation, we might interact with a database using PHP. This involves using PHP's database connectivity features (e.g., MySQLi or PDO) within the PHP script that handles the Ajax request.
Checking Script support
As Ajax depends on client side scripting, we need to check the script support is enabled ( in browser ) or not. Here is the code we can use to display message if scripting is disabled.
<noscript>Your browser does not support scripts, you have to enable it to run this page</noscript>

Ajax combined with PHP is so interesting, I thought programming with ajax is difiicult but now my mind is opened. So if I can ask, Is there a specific part of which when I am saying I want to learn Ajax, I should start with?
