Notice: Undefined index: page in E:\PHP\test.php on line 14

治瞬恢伪镜木褪php.ini鹊reporting部份修改，notice不@示
error_reporting = E_ALL; display all errors, warnings and notices
改成
error_reporting = E_ERROR & ~E_NOTICE & ~E_WARNING

不然
isset($_GET["page"])做if-else判!!

----修正後原始a如下----
if(isset($_GET["page"]))$page=$_GET["page"];
else $page=1;
