Смысл: The text provides a technical comparison of three methods for serving files via PHP: using the native readfile() function, reading files manually in chunks, and delegating the delivery to the web server (Apache or Nginx) for maximum performance.
A technical guide comparing PHP's internal file delivery functions with high-performance web server offloading via Apache XSendFile and Nginx X-Accel-Redirect.
Смысл: The main idea is to provide a data-driven comparison of different configuration file formats for PHP to help developers choose between performance, readability, and flexibility.
A benchmark of PHP configuration formats reveals that serialized data is the fastest, while a hybrid of PHP scripts and serialized caching is the most optimal for both flexibility and speed.
Смысл: The main idea is to present various programmatic ways to retrieve a file extension in PHP, comparing their logic and execution speed to help developers choose the most efficient approach.
The author compares five different PHP methods for extracting file extensions, concluding with performance benchmarks that favor the strrchr/substr approach.
