Question

考虑以下代码：

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();

是否可以在log方法中获取调用函数的类名和函数名？（没有明确地将它们发送到日志功能）

PS：我认为trigger_error就像窗帘背后那样，所以我想知道我是否能做到这一点。

Answer 1

我相信你正在寻找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debug_backtrace可以提供帮助。查看PHP手册以获取功能描述：
