輸出調用函數信息

Question

考慮以下代碼：

class App { 
    public static function log($msg) { 
    echo $msg; 
    //echo WHAT_CLASS_CALLED_LOG; 
    //echo WHAT_LINE_CALLED_LOG; 
} 
} 


class Tester { 
public function Make() { 
    App::log('test'); 
} 
} 


$obj = new Tester(); 
$obj->Make(); 

是可能得到的類名，並在日誌方法調用函數的函數名？ （沒有明確地將它們發送到日誌功能）

PS：我認爲trigger_error的作用就像在窗簾後面，所以我想知道如果我能做到這一點。

Answer 1

我相信你正在尋找debug_backtrace。

Returns an associative array. The possible returned elements are as follows: 

Name  Type Description 
function string The current function name. See also __FUNCTION__. 
line  integer The current line number. See also __LINE__. 
file  string The current file name. See also __FILE__. 
class  string The current class name. See also __CLASS__ 
object  object The current object. 
type  string The current call type. If a method call, "->" is returned. If a static method call, "::" is returned. If a function call, nothing is returned. 
args  array If inside a function, this lists the functions arguments. If inside an included file, this lists the included file name(s).

可能是debug_backtrace可以提供幫助。檢查PHP-手冊的功能描述：
