Introduction:
I recently used Thinkphp5.1 for development, and an error occurred when using the LOG_PATH constant (log path). Because I have been using the 5.0 framework before, after switching to version 5.1, this situation occurred. I understand that the official adjustment has been made, so I went there Read the official instructions.

Constant adjustment
Thinkphp5.1 cancels all built-in constants in the framework (does not affect custom constants in the application code). If you need to obtain them, please use the built-in methods of the think\facade\App class and the think\facade\Env class to obtain them.
| 5.0 Constant | 5.1 How to Obtain |
|---|---|
| EXT | Cancel, use .php |
| IS_WIN | cancel |
| IS_CLI | cancel |
| DS | Use PHP comes with DIRECTORY_SEPARATOR |
| ENV_PREFIX | Cancel, use PHP_ |
| THINK_START_TIME | App::getBeginTime() |
| THINK_START_MEM | App::getBeginMem() |
| THINK_VERSION | App::version() |
| THINK_PATH | Env::get(‘think_path’) |
| LIB_PATH | Env::get(‘think_path’) . ‘library/’ |
| CORE_PATH | Env::get(‘think_path’) . ‘library/think/’ |
| APP_PATH | Env::get(‘app_path’) |
| CONFIG_PATH | Env::get(‘config_path’) |
| CONFIG_EXT | App::getConfigExt() |
| ROOT_PATH | Env::get(‘root_path’) |
| EXTEND_PATH | Env::get(‘root_path’) . ‘extend/’ |
| VENDOR_PATH | Env::get(‘root_path’) . ‘vendor/’ |
| RUNTIME_PATH | Env::get(‘runtime_path’) |
| LOG_PATH | Env::get(‘runtime_path’) . ‘log/’ |
| CACHE_PATH | Env::get(‘runtime_path’) . ‘cache/’ |
| TEMP_PATH | Env::get(‘runtime_path’). ‘temp/’ |
| MODULE_PATH | Env::get(‘module_path’) |
Note: When obtaining path variables through the get method of the Env class, it is not case sensitive.
Thinkphp5.1 method to print independent log:
/**
* 打印日志
* $msg 日志内容
*/
function printLog($msg) {
$path=LOG_PATH .date('Y-m-d').".txt";
file_put_contents($path, "【" . date('Y-m-d H:i:s') . "】\r\n" . $msg . "\r\n\r\n", FILE_APPEND);
}
