Take WordPress plugin as an example of use cases:
Add in the appropriate location of the plugin main file (if the above code is placed in the class-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 class-coolwp-debug-log.php directory under 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.

In the WordPress environment, you can use the filter hook:

Apply_filters (' Cwp_debug_log_file_name ', $file _name)

To modify the name of the default log file.
