Why does echo realpath(RUNTIME_PATH); produce different results in the same method?

In order to enable custom error and exception handling mechanisms to capture fatal errors, trigger_error($e['message']);

has been added to the fatalError() method of thinkphp
<code>// 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'));
