Why the same method echo Realpath (Runtime_path); will produce different results?

In order to allow the custom error and exception handling mechanism to capture fatal errors, the thinkphp () method adds Trigger_error ($e [' message ') to the fatalerror () approach;

// 重新设置错误及异常处理机制 set_error_handler(array('\Think\ErrorLog','phplog')); set_exception_handler(array('\Think\ErrorLog','phplog'));

// 致命错误捕获static public function fatalError() {    Log::save();    if ($e = error_get_last()) {        switch($e['type']){          case E_ERROR:          case E_PARSE:          case E_CORE_ERROR:          case E_COMPILE_ERROR:          case E_USER_ERROR:            ob_end_clean();            // 抛出用户级别错误，让自定义的错误机制(phplog)能够捕获            trigger_error($e['message']); //自己添加的            self::halt($e);            break;        }    }}
