Simple example of PHP stack debugging operation

This article illustrates the PHP stack debugging operation. Share it for your reference, as follows:

Do you want to know the current function is called by which files, if we know these paths, we can very well understand the process of the execution of the program, this is very important, but also to understand the basis of other programs, so here I will introduce you to a stack debugging method in php, in fact, it is a built-in php function debug_backtrace() ;

The following is a little introduction under it, the specific or to see the manual oh, like to see the manual programmers are promising

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

Run results:

Array
(
[0] = > Array
(
[file] = > D:\wwwroot\CodeIgniter\application\controllers\finance\channel.php
[line] = > 128
[function] = > get_total_rows
)
[1] = > Array
(
[file] = > --
[line] = > --
[function] = > index
)
[2] = > Array
(
[file] = > D:\wwwroot\CodeIgniter\application\controllers\finance\channel.php
[line] = > 46
[function] = > call_user_func
)
[3] = > Array
(
[file] = > --
[line] = > --
[function] = > get_nav
)
[4] = > Array
(
[file] = > D:\wwwroot\CodeIgniter\system\core\CodeIgniter.php
[line] = > 360
[function] = > call_user_func_array
)
[5] = > Array
(
[file] = > D:\wwwroot\CodeIgniter\index.php
[line] = > 205
[function] = > require_once
)
)

Here is the printed array, which is very good
