take WordPress plugin as an example of use cases:
add in the appropriate location of the plugin master file (if the above code is placed in theclass-coolwp-debug-log.php file):

$this->is_debug = true;if ($this->is_debug) {require_once (Plugin_dir_path (__file__)). '    Classes/class-coolwp-debug-log.php '); $this->log = new Coolwp_com_log ();}

If __file__ is defined as a constant someone_this in the plug-in main file, you can pass the Someone_this as a parameter to Coolwp_com_log (), for example:

$this->log = new Coolwp_com_log (someone_this);

The difference between the pass-through parameter is the location of the log file, if the parameter is not passed, the log file is located in the directory of class-coolwp-debug-log.php in the Debug directory, if the Someone_this parameter is passed, then, The log files are located under the Debug directory in the plug-in home directory. The file name for the log file is Debug_*******log.

Log entries default to Beijing time.
