ThinkPHP base class library
The class library is the core part of ThinkPHP, and ThinkPHP manages all system class libraries together through the concept of base class library. The core base class library includes basic classes and common tool classes necessary to complete the universal development of the framework.
The base class library is located in the Lib/Think directory under the ThinkPHP system directory and consists of the following parts:
Core: Core class library package
Db: Database class library package
Exception: Exception handling class library package
Template: Built-in template engine Class library package
Util: System tool class library package
Core core class library
Core core class library includes the following Class file (directory):
Think.class.php: System base class
App.class.php: Application class, execution Application Management
Action.class.php: Controller base class
Model.class.php: Model base class
Model/AdvModel.class.php: Advanced model class
Model/RelationModel.class.php: Relation model class
-
Model/ViewModel.class.php: View model class
Log.class.php: Log processing class
View.class .php: View output class
Db database class library
Db core class library includes the following class files (directories):
Db.class.php: Database middle layer implementation class
Driver/DbMysql.class.php: Mysql database driver class
Driver /DbMysqli.class.php:Mysqli database driver class
- ##Driver/DbPdo.class.php:PDO database driver class
- Driver/DbPgsql .class.php:Pgsql database driver class ##Driver/DbSqlite.class.php:Sqlite database driver class
- ##Driver/DbOracle.class .php:Oracle database driver class
- Driver/DbMssql.class.php:Mssql database driver class
- Driver/DbIbase.class.php :Ibase database driver class
- There are different database driver classes for different databases in the Driver directory, and then through the Db.class.php database middle layer to implement class processing, it is displayed in ThinkPHP What users have in front of them is a unified database operation model.
- TagLib.class.php: Tag library base class
- TagLib/TagLibCx.class.php:CX tag library parsing class
- TagLib/TagLibHtml.class.php:HTML tag library parsing class
- Util system tool library package
- Cache.class.php: Cache management class
- Cookie.class.php: Cookie management Class
- Debug.class.php: System debugging class
- Dispatcher.class.php: URL parsing, routing and dispatch management class
- HtmlCache.class.php: Static cache class
- Session.class.php: Session management class
- Widget.class.php: Plug-in application class
- Cache/: Various types of cache class file directories, including: file cache class, Sqlite cache class, Apachenote cache class, Memcache cache class , Xcache cache class, database type cache class, etc.
Template/: Template engine parsing class directory, including: EaseTemplate template engine parsing class, TemplateLite template engine parsing class, Smart template engine parsing class, Smarty template engine parsing class, Think template engine parsing class
ThinkPHP extension class library
ThinkPHP official website provides a lot of additional base class library extensions. These extension class libraries must be placed in the ORG under the ThinkPHP system directory/Lib directory. Or managed within the Com class library package.
For the class library that needs to be added to the extended class library package, you can directly copy the class library file with the path to the extended class library management directory and then use it. For example, if you want to use Util/Page.class.php paging extension class library, go directly to the extension class library management directory to form Lib/ORG/Util/Page.class.php.
You need to use the import command to import the extended class library before it can be used. For details, please refer to this section "ThinkPHP import class library import".
Application Class Library
Application class library refers to the class library that is defined or used in the project. The application class library directory is located in the Lib directory under the project directory.
The above is an introduction to the core of ThinkPHP - class library. Understanding the ThinkPHP class library will help us understand the hierarchy and working principles of ThinkPHP. When necessary, referring to the source code of these class libraries will also help solve the problem.

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
