二、debug_backtrace()

三、Exception类中的getTraceAsString()成员函数返回一个调用堆栈

一、debug_print_backtrace()

//调用函数parent_func

function child_func() {

parent_func();

}

//调用grandparent_func

function parent_func() {

grandparent_func();

}

//打印调用堆栈

function grandparent_func() {

debug_print_backtrace();

}

//主函数调用

child_func();

#0 grandparent_func() called at [D:\wamp\www\temp.php:10]

#1 parent_func() called at [D:\wamp\www\temp.php:5]

#2 child_func() called at [D:\wamp\www\temp.php:19]

二、debug_backtrace()

//调用函数parent_func

function child_func() {

parent_func();

}

//调用grandparent_func

function parent_func() {

grandparent_func();

}

//打印调用堆栈

function grandparent_func() {

var_dump(debug_backtrace());

}

//主函数调用

child_func();

三、getTraceAsString()

Exception类中的getTraceAsString()成员函数返回一个调用堆栈

//调用函数parent_func

function child_func() {

parent_func();

}

//调用grandparent_func

function parent_func() {

grandparent_func();

}

//打印调用堆栈

function grandparent_func() {

$e = new Exception;

var_dump($e->getTraceAsString());

}

//主函数调用

child_func();

D:\wamp\www\temp.php:16:string '#0 D:\wamp\www\temp.php(10): grandparent_func()

#1 D:\wamp\www\temp.php(5): parent_func()

#2 D:\wamp\www\temp.php(20): child_func()

#3 {main}' (length=162)
