Advanced Guide to Python asyncio: From Beginner to Expert
Mar 04, 2024 am 09:43 AM
Concurrent and Asynchronous Programming Concurrent programming deals with multiple tasks executing simultaneously, asynchronous programming is a type of concurrent programming in which tasks do not block threads. asyncio is a library for asynchronous programming in python, which allows programs to perform I/O operations without blocking the main thread. Event loop The core of asyncio is the event loop, which monitors I/O events and schedules corresponding tasks. When a coroutine is ready, the event loop executes it until it waits for I/O operations.

PHP vs. Ajax: Solutions for creating dynamically loaded content

Ajax (Asynchronous JavaScript and XML) allows adding dynamic content without reloading the page. Using PHP and Ajax, you can dynamically load a product list: HTML creates a page with a container element, and the Ajax request adds the data to that element after loading it. JavaScript uses Ajax to send a request to the server through XMLHttpRequest to obtain product data in JSON format from the server. PHP uses MySQL to query product data from the database and encode it into JSON format. JavaScript parses the JSON data and displays it in the page container. Clicking the button triggers an Ajax request to load the product list.
