<?php

/* 使用debug_print_backtrace() 或 debug_backtrace() 打印栈轨迹 */

function fun1() {
	print "Hello world!\n";
	fun2();
}

function fun2() {
	Class1::fun3();
}

Class Class1 {
	static function fun3() {
		$class2 = new Class2();
		$class2->fun4();
	}
}

class Class2 {
	function fun4() {
		debug_print_backtrace();
		$backtrace = debug_backtrace();
		echo '<pre>';
		print_r($backtrace);
	}
}

fun1();

输出：
