AJAX PHP

This lesson is part of PHP · All levels

Summary

In AJAX, JavaScript sends a request to a PHP file that acts as an endpoint. PHP processes requests, runs logic, and then responds with concise data like JSON or HTML snippets. JavaScript then displays the responses to the page without reloading, so the two work together.

Key points

The flow: JS sends requests, PHP processes, JS displays responses without reloading.
AJAX endpoints should respond concisely to the data required.
Customize the response header, such as application/json for JSON data.
PHP can recognize AJAX requests through header like X-Requested-With.
