php中堆疊調試

你是否想知道當前函數被哪些文件調用了，如果知道了這些路徑，我們就能很好的理解程序的執行過程，這是非常重要的，也是了解別人程序的基礎，那麼這裡我就給大家介紹一種php中的堆疊調試的方法，其實就是php內建的一個函數debug_backtrace();

下面是就稍微介紹一下吧，具體還是要看手冊哦，喜歡看手冊的程式設計師才是前途無量的

<code>$statcks = debug_backtrace();
$tmp_arr = array();
<span>if</span>(!$stacks) <span>return</span> $tmp_arr;
foreach($stacks as $k=>$v)
        {
            $tmp[$k][<span>'file'</span>] = isset($v[<span>'file'</span>]) ? $v[<span>'file'</span>] : <span>'--'</span>;
            $tmp[$k][<span>'line'</span>] = isset($v[<span>'line'</span>])? $v[<span>'line'</span>] : <span>'--'</span>;
            $tmp[$k][<span>'function'</span>] = isset($v[<span>'function'</span>]) ? $v[<span>'function'</span>] : <span>'--'</span>;
        }


Array
(
    [<span>0</span>]<span> =></span> Array
        (
            [file]<span> =></span><span>D</span>:\wwwroot\CodeIgniter\application\controllers\finance\channel.php
            [line]<span> =></span><span>128</span>
            [<span>function</span>]<span> =></span> get_total_rows
        )

    [<span>1</span>]<span> =></span> Array
        (
            [file]<span> =></span> --
            [line]<span> =></span> --
            [<span>function</span>]<span> =></span> index
        )

    [<span>2</span>]<span> =></span> Array
        (
            [file]<span> =></span><span>D</span>:\wwwroot\CodeIgniter\application\controllers\finance\channel.php
            [line]<span> =></span><span>46</span>
            [<span>function</span>]<span> =></span> call_user_func
        )

    [<span>3</span>]<span> =></span> Array
        (
            [file]<span> =></span> --
            [line]<span> =></span> --
            [<span>function</span>]<span> =></span> get_nav
        )

    [<span>4</span>]<span> =></span> Array
        (
            [file]<span> =></span><span>D</span>:\wwwroot\CodeIgniter\system\core\CodeIgniter.php
            [line]<span> =></span><span>360</span>
            [<span>function</span>]<span> =></span> call_user_func_array
        )

    [<span>5</span>]<span> =></span> Array
        (
            [file]<span> =></span><span>D</span>:\wwwroot\CodeIgniter\index.php
            [line]<span> =></span><span>205</span>
            [<span>function</span>]<span> =></span> require_once
        )

這裡是打印出來的數組，非常的好了
