[php] 调试利器

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

msg:test#0  a->say(test) called at [/var/www/test/test0723.php:12]#1  b->say(test) called at [/var/www/test/test0723.php:19]#2  c->__construct(test) called at [/var/www/test/test0723.php:23]
