Implementing JavaScript Brotli and Gzip Compression
Article Introduction：Both Brotli and Gzip can be used for front-end optimization, but Brotli has higher compression rate and better Gzip compatibility. It is recommended to enable Brotli first and retain Gzip as a downgrade solution; .br and .gz files can be generated through Webpack's compression-webpack-plugin plugin, and the compression level, file type and threshold are configured; when deploying, the corresponding module and MIME types must be configured on the server (such as Nginx or Apache), and the .br files must be returned in order, followed by .gz, and the original files; precautions include checking the Accept-Encoding request header, file path, module loading, MIME type, avoiding double compression and

Managing Gettext Translations on Shared Hosting
Article Introduction：Core points
Gettext is a popular method for translation management of PHP websites, but it has a significant drawback: Apache caches translations, which means that unless the engine is restarted, updates to translated files will not be visible. This is especially problematic on shared hosting, as administrator privileges are often not available.
Audero Shared Gettext is a PHP library that allows developers to bypass Apache's cache of translations loaded through the gettext() function. The library uses a simple trick to create a mirrored copy of the translation file, tricking Apache into thinking it as a new, irrelevant translation, thus avoiding caching issues.

How to handle File Uploads securely in PHP?
Article Introduction：To safely handle PHP file uploads, you need to verify the source and type, control the file name and path, set server restrictions, and process media files twice. 1. Verify the upload source to prevent CSRF through token and detect the real MIME type through finfo_file using whitelist control; 2. Rename the file to a random string and determine the extension to store it in a non-Web directory according to the detection type; 3. PHP configuration limits the upload size and temporary directory Nginx/Apache prohibits access to the upload directory; 4. The GD library resaves the pictures to clear potential malicious data.

How to create a custom exception?
Article Introduction：Custom exceptions are implemented in Python by inheriting the Exception class or its subclasses, which are used to improve code readability and targeted error handling. When built-in exceptions cannot meet specific business needs, for example, you need to distinguish between multiple user input error scenarios, you can create different exception types such as InvalidEmailError and PasswordTooShortError. The creation method is simple. You only need to define a new class. You can also add initialization parameters such as message and error_code to provide more information to assist in debugging. Suitable scenarios for using custom exceptions include modular projects, business rule verification, and third-party library development, such as the data parsing module that defines ParseError

How to set environment variables in PHP environment Description of adding PHP running environment variables
Article Introduction：There are three main ways to set environment variables in PHP: 1. Global configuration through php.ini; 2.

Persistence policies include configuration files (such as php.ini or web server configuration), .env files are loaded with dotenv library, and dynamic injection of variables in CI/CD processes. Security management sensitive information should be avoided hard-coded, and it is recommended to use.en
