Based on the Yaf project, some global class libraries are used, most of which come from various open source projects such as Zend/Top Framework and so on.

No need to install extensions, comes with dictionary, easy to use Use scws, which many people are familiar with, and the other one is phpanalysis made by IT Plato Please refer to the index.php file example for usage.

This is a complete solution for online browsing in swf format similar to Baidu Library: it supports the upload of multi-format documents such as office/pdf/txt/html. This solution uses open source free software throughout the entire process, with zero cost. The project currently implements simple uploading and automatic conversion. If it is to be used in actual projects, more factors need to be considered, which are not listed here. If you have any questions, please directly issue it or submit a pull request to improve it together. Thank you.

A simple PHP image processing class library. Although it does not have many functions, it is enough for now.

Introducing a very strong and complete image processing class with relatively complete functions. Basic image processing, used to complete image indentation and watermark addition, When the watermark image exceeds the size of the target image, the watermark image can automatically adapt to the target image and shrink.
