Using Background Processing to Speed Up Page Load Times

Core points Background processing significantly improves page loading speed: transfers heavy tasks to background processing, releases main thread resources, and focuses on page loading, thereby improving user browsing experience. There are two core components of background processing: task queues and worker processes. The application creates pending tasks, while the worker processes extract tasks one by one from the queue for processing. Multiple worker processes can be processed in parallel to speed up. Technology stack selection: Use Beanstalkd task queue to store tasks, Symfony Console components to implement worker processes (as console commands), and Supervisor manages worker processes. Image library optimization: Avoid image scaling on first request (this increases initial loading burden)

Quick Tip: How to Filter Data with PHP

Key Points Never trust external input in the application. It is crucial to filter any data contained in your application to prevent attackers from injecting code. The two main types of data filtering in PHP are verification and cleaning. Verification ensures that external inputs meet expectations, while cleaning removes illegal or unsafe characters from external inputs. PHP provides a range of filters for verification and cleaning. These filters can be applied using the filter_var() and filter_input() functions to make your PHP applications safer and more reliable. This article will explore why anything contained in a filter application is so important. In particular, we will look at how to verify and clean external data in PHP

HTTP/2: Background, Performance Benefits and Implementations

HTTP/2: Network protocol that significantly improves web page loading speed Core points: HTTP/2 (released in 2015) solves the latency problem of its predecessor HTTP/1.1 by compressing HTTP headers, implementing server pushes and multiplexing requests on a single connection. It is also designed to solve the problem of head-of-team blocking and requires encryption by default. The transition from HTTP/1.1 to HTTP/2 is not without challenges, as backward compatibility is required with existing websites. Any improvement to the protocol must be implemented in a way that does not interrupt the Internet. All mainstream browsers currently support HTTP/2, however, they require that all HTTP/2 requests must be encrypted, which is not a requirement of the HTTP/2 specification itself.

Quick Tip: How to Cache Data in PHP

This tutorial quickly explains the PHP caching mechanism and its applications. Efficient performance is the key to PHP application development. Facing thousands or even millions of users, the performance and availability of web applications face huge challenges. Caching technology can effectively avoid performance bottlenecks and improve application efficiency. Core points The cache stores frequently accessed data in a temporary location, reducing the number of times data is read from the original location, thereby improving PHP application performance. Output buffering is a technique in PHP that stores script output in a buffer before being displayed to the user, allowing modifications or other operations before being displayed. PHP provides a variety of cached data functions, such as apc_store(), memcache_set() and xcache_s

Quick Tip: How to Manage Error Reporting in PHP

This article will explore the skills of PHP error reporting and introduce how to use PHP tools to handle errors in a controlled manner, thereby saving debugging time. PHP is essentially a "lightweight exception" programming language. This means that, while it supports exception handling, the script continues to execute unless a fatal error occurs, no matter what happens. For example:

PHP program to find the perimeter of rectangle

Problem description Given the length and width of the rectangle, we need to implement a PHP program to calculate its perimeter. A rectangle is an enclosed two-dimensional figure with 4 sides. The opposite sides are equal and parallel, and the angle formed by adjacent sides is equal to 90 degrees. The perimeter is the sum of all sides; in other words, the perimeter is twice the sum of length and width. In this tutorial, we will learn how to find the perimeter of a given rectangle in PHP using different methods. Rectangle perimeter formula The formula for the circumference of the rectangle is as follows: $${perimeter = 2 × (length and width)}$$ in: Long - horizontal distance. Width - Vertical distance. Example Let's understand the problem description with some input and output examples. enter Length = 10 units Width = 5 units
