自动使用相对于函数调用位置的 __LINE__ 和 __FILE__

我有一个函数log($text)

这一切所做的就是写$text到数据库。

我想包括__LINE__ and __FILE__，但不想像我现在那样每次都将其作为参数包含在内：

function log($text,$file = null, $line = null){
    // write $text to db using the three paramters
}

如果我改变$file = null to $file = __FILE__它使用函数所在的文件名，而不是调用函数的位置。

有没有办法解决？

_{Although the question is identical, the answers seem to focus on some other topic: function name($param, $line = __LINE__, $file = __FILE__) {}; https://stackoverflow.com/questions/3387320/function-nameparam-line-line-file-file also, not using Zend framework: how to have php get the __LINE__ or __FILE__ value where a function is called https://stackoverflow.com/questions/7184280/how-to-have-php-get-the-line-or-file-value-where-a-function-is-called?rq=1}
