thinkphp5 method of loading static resource paths and constants
This article mainly introduces the relevant information about thinkphp5's method of loading static resource paths and constants. Friends in need can refer to
1. Loading static resource paths
Versions greater than 5.0.4 can be used directly
__ROOT__: project directory
__STATIC__: static directory under the project directory
__JS__: static/js directory under the project directory
__CSS__: static/css directory under the project directory
We can use the view template to print the specific paths of these constants
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Insert title here</title> </head> <body> __ROOT__<br> __STATIC__<br> __JS__<br> __CSS__<br> </body> </html>
The page output is as follows:
/ /projectname/public/static /projectname/public/static/js /projectname/public/static/css
Open the config file under the application folder. You can customize resource constants according to your own needs. After defining the constants, you can Constants are used in template files.
For example:
<?php return [ 'view_replace_str' => [ '__PUBLIC__'=>'../public/static/admin', '__ROOT__' => '/', '__APP__' => 'app/admin/', ] ];
2. Predefined constants
Predefined constants refer to the system The built-in defined constants will not change with changes in the environment, including:
EXT Class library file suffix (.php)
THINK_VERSION Framework version number
3. Path constants
System and application path constants are used for system default directory specifications and can be changed by redefining them. If you do not want to customize the directory, these constants are generally No changes are required.
DS 当前系统的目录分隔符 THINK_PATH 框架系统目录 ROOT_PATH 框架应用根目录 APP_PATH 应用目录(默认为application) CONF_PATH 配置目录(默认为APP_PATH) LIB_PATH 系统类库目录(默认为 THINK_PATH.'library/') CORE_PATH 系统核心类库目录 (默认为 LIB_PATH.'think/') TRAIT_PATH 系统trait目录(默认为 LIB_PATH.'traits/') EXTEND_PATH 扩展类库目录(默认为 ROOT_PATH . 'extend/') VENDOR_PATH 第三方类库目录(默认为 ROOT_PATH . 'vendor/') RUNTIME_PATH 应用运行时目录(默认为 ROOT_PATH.'runtime/') LOG_PATH 应用日志目录 (默认为 RUNTIME_PATH.'log/') CACHE_PATH 项目模板缓存目录(默认为 RUNTIME_PATH.'cache/') TEMP_PATH 应用缓存目录(默认为 RUNTIME_PATH.'temp/')
4. System constants
System constants will change or be set as the development environment changes Change brings about change.
IS_WIN 是否属于Windows 环境 IS_CLI 是否属于命令行模式 THINK_START_TIME 开始运行时间(时间戳) THINK_START_MEM 开始运行时候的内存占用 ENV_PREFIX 环境变量配置前缀

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.
