A PHP Log class for debuging

Share a debug log class that I used to get in WordPress development.

 dir = dirname ($main _file). Directory_separator. ' Debug '.            Directory_separator; $file _name = ' debug_ '. MD5 ($main _file).            Log '; $this->debug_file_name = (function_exists (' apply_filters '))? Apply_filters (' Cwp_debug_log_file_name ', $file _ name). '. Log ': $file _name.            Log ';            $this->f_path = $this->dir. $this->debug_file_name;         $this->check_log_file (); /** * Adding Log Item * @param string $text: Adding content */Public function A            DD ($text) {date_default_timezone_set (' Asia/shanghai '); if (Is_array ($text) | |            Is_obeject ($text)) {$text = Json_encode ($text);            } $fp = fopen ($this->f_path, "a");            Flock ($FP, LOCK_EX); Fwrite ($FP, "". Date ("Y-m-d h:i:s", Time ()). " \ n ". $text."            \ n ");            Flock ($FP, lock_un);            Fclose ($FP);            return true; }/** * Checking the log file anD path.            * @return NULL */Private Function Check_log_file () {$is _dir = Is_dir ($this->dir);            $is _file = file_exists ($this->f_path);            if ($is _dir && $is _file) return; if (! $is _dir| |!                $is _file) {if (! $is _dir) {$md = mkdir ($this->dir,0777,true);                      } if (! $is _file) {$fp = fopen ($this->f_path, "a");                 Fclose ($FP); }}}}/*//class*/}/*all done.*/?>

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.
