$sql="select goods_id,goods_name,goods_price from tdb_goods order by goods_id limit ".(($page-1)*10).",10"; 用空格法我這里還是報錯，這個不報錯。至于出現Notice: Undefined index: p in 錯誤的朋友，那是你沒傳參數給$page 用這個 http://localhost/php/mypage.php?p=1
Notice: Undefined index: p in F:\PHP\apache\htdocs\php-project\mypage.php on line 6
Warning: mysql_fetch_assoc() expects parameter 1 to be resource, boolean given in F:\PHP\apache\htdocs\php-project\mypage.php on line 24
跟著打還是報錯 ，未定義的變量 ....然后打開也是顯示資源不存在
報錯如下：
Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in D:\e2php_12_20\htdocs\article\mypage.php on line 23
Warning: mysql_free_result(): 同上
Warning: mysql_fetch_array(): 同上
