PHP Call nginx Mod_zip Module Package zip file _php Tutorial

PHP itself has a zip module that can produce zip files. However, this zip module can only be packaged using local files. If you need to package output files from the network, you have to save the temporary files first. It is a cup of paper when the number of documents is large or the file is big. In addition, PHP to output a large package of files will occupy the PHP process a lot of time, affecting the concurrency capability. Nginx has a third-party module, Mod_zip. You can also export a zip p
