XiunoPHP4.0 is not a framework in the strict sense. It does not require you to organize your code or inherit BaseControl and BaseModel. Therefore, it will not "frame" you like other frameworks. It just makes some enhancements to PHP, adds some initial variables, and global functions. In terms of development philosophy, use as little OO as possible and most functional encapsulation, which is conducive to HHVM compilation/opcode caching, perfectly supports PHP7, and advocates the following principles: 1. Do not include variables; 2. Do not use eval(), regular Expression e modifier; 3. Do not use autoload; 4. Do not use $$var multiple variables; 5. Do not use PHP advanced features __call__set__get and other magic methods; 6. Try to use function encapsulation functions and distinguish modules through prefixes.
