Quick Tip: How To Read a Local File with PHP
Article Introduction：PHP provides three native functions for local file operations: file(), file_get_contents() and fopen(). Although complete libraries are built around these functions, they are still the preferred method of quickly manipulating PHP files.
We will first understand the functions of these functions and then look at their working examples.
file() and file_get_contents()
File() and file_get_contents() work very similarly. They all read the entire file. However, file() reads the file into the array, while file_get_contents() reads the file

How does the FileReader API work?
Article Introduction：FileReader API can read user device files and process content with JavaScript. It supports reading text files and binary files, such as 1. Read as text such as .txt, .csv, .json; 2. Read as DataURL for previewing pictures; 3. Read as ArrayBuffer for binary operations or sending raw data. It works asynchronously and does not block the main thread. The usage methods include: 1. Obtain the file from; 2. Create a FileReader instance; 3. Call the corresponding reading method; 4. Process the result in the onload event. For example, when previewing the image, read the file through readAsDataURL and then select the file in the onload

PHP Master | ?Understanding Streams in PHP
Article Introduction：Core points
PHP streaming is a powerful tool for generalizing file, network and data compression operations. They can be read or written linearly and can fseek() anywhere in the stream. Each stream has a wrapper for handling specific protocols or encodings.
PHP provides built-in wrappers, protocols, and filters, and allows the creation and registration of custom wrappers, protocols, and filters. The default wrapper is file://, which is used every time you access the file system. Other wrappers include wrappers for HTTP, Amazon S3, MS Excel, Google Storage, Dropbox, and Twitter.
The stream context is a stream-specific parameter

What is the function of line in python common operations for python text processing line
Article Introduction：In Python, line is not a function, but a common variable name that stores single-line text read from a file. Common operations for processing lines include: 1. Read and process each line, using a for loop to process line by line; 2. Remove line breaks, use strip() or rstrip() methods; 3. Split lines, use split() methods; 4. Find and replace, use replace() methods; 5. Regular expression processing, use re module. These operations can improve efficiency and robustness by optimizing memory management, performance optimization, error handling, and following best practices.

Working with the File System in Deno
Article Introduction：This article will dive into Deno and create a command line tool for searching for text in files and folders. We will use various API methods provided by Deno to read and write to the file system.
In the previous article, we built a command line tool using Deno to make requests to third-party APIs. In this article, we will temporarily ignore network operations and build a tool that allows you to search for text in files and folders within the current directory - tools like grep.
Note: The tools we build are not optimized and efficient as grep, and we are not aiming to replace it! The purpose of building such a tool is to be familiar with Deno's file system API.

An Introduction into Event Loops in PHP
Article Introduction：PHP event loop: a tool for asynchronous programming
Core points
A PHP event loop is a programming structure used to wait for events or messages in a scheduler, especially for handling asynchronous operations.
Traditional PHP programming is synchronous, performing one operation at a time, and waiting for each operation to complete before continuing with the next operation. While the event loop allows asynchronous programming, where an operation can be started and then put on hold until the result is ready, other operations can be performed during this time.
Library such as ReactPHP or Amp provides the necessary interfaces and classes to create and manage PHP event loops, allowing better use of resources and shorter response times, especially in applications that need to handle a large number of concurrent connections.
