class a{ function construct(){ echo "start to construct a obj\n"; } function pide($a,$b) { //exit(1);//destruct called return $a/$b; //destruct called when $b=0; } function add($a,$b) { throw new Exception ("daone");//destruct called return $a+$b; } function destruct(){ echo "start to destruct\n"; } } try{ $first = new a(); //$r = $first->pide(4,0); $first->add(4,0); } catch(Exception $e) { echo "cath exception \n"; }
从上面的例子可以看出,php抛出异常(不管外面有没有try catch),直接退出的情况下,都会调用析构函数。
以上就是php:析构函数调用的示例代码的详细内容,更多请关注Gxl网其它相关文章!
