如果我們想知道某個方法被誰調用了? debug_print_backtrace可以解決

不過這是一個PHP5的專有函數,好在哪裡pear中已經有了實作,

<?php class a{ function say($msg) { echo "msg:".$msg; echo "<pre class="brush:php;toolbar:false">";debug_print_backtrace(); } } class b { function say($msg) { $a = new a(); $a->say($msg); } } class c { function __construct($msg) { $b = new b(); $b->say($msg); } } $c = new c("test");
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]
