- 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

- 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

- PHP Program to Check if a Number is an Armstrong Number
- Armstrong Number The Armstrong number refers to the sum of n powers of each digit of a number equal to the number itself, where n is the number of digits of the number. This article will discuss how to check if a given number is an Armstrong number. Example Let's learn about the Armstrong number with some input and output examples. enter 9474 Output yes explain This is a four-digit number. The numbers for this number are 9, 4, 7 and 4. 9474 = 94 44 74 44= 6561 256 2401 256= 9474 So, this is an Armstrong number. enter 153 Output yes explain This is a triple digit number.

- PHP Program for Binary to Decimal Conversion
- Binary to decimal conversion refers to the process of converting a binary number (i.e., a number represented by only two digits 0 and 1) to its equivalent decimal number (i.e., in the form of 10 as a base). This article will explain how to convert the binary form of a number to a decimal form in PHP using different methods. How to convert binary to decimal? Binary numbers (binary) are composed only of 0 and 1 bits used by machines, and decimal numbers are decimal numbers used by humans. To convert a binary number to a decimal number, multiply each binary number by its position power (starting from 0 on the right), and add all the results. Example 1 Input: Binary number = 101 Output: decimal
