Stack debugging in php

Do you want to know which files are called by the current function? If we know these paths, we can well understand the execution process of the program. This is very important and is also the basis for understanding other people's programs. So here I will give you Let’s introduce a stack debugging method in php. It is actually a function built into phpdebug_backtrace();

The following is a brief introduction. You still need to read the manual for details. Programmers who like to read manuals are The promising

<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

        )

        )

            [<span>function</span>]<span> =></span> call_user_func

            [<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

            [<span>function</span>]<span> =></span> call_user_func_array
        )
