如果我们想知道某个方法被谁调用了? debug_print_backtrace可以解决!~
测试代码
1 <?php 2 class a{ 3 function say($msg) { 4 echo "msg:".$msg; 5 echo "<pre class="brush:php;toolbar:false;">";debug_print_backtrace(); 6 } 7 } 8 9 class b {10 function say($msg) {11 $a = new a();12 $a->say($msg);13 }14 }15 16 class c {17 function __construct($msg) {18 $b = new b();19 $b->say($msg);20 }21 }22 23 $c = new c("test");输出结果
