一直提示mysql_fetch_array函數(shù)參數(shù)不對，是什么原因呢
$start = ($page-1)*$pagesize; $sql = "select * from user limit$start,$pagesize";
?Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in index.php on line 16?
我提交一直出現(xiàn)這個(gè)警告，是什么原因呢，求解答！

mysql_fetch_array()現(xiàn)在已經(jīng)被棄用了，使用mysqli或者PDO擴(kuò)展，比如：mysqli_fetch_array()

$sql = "select * from user "

$offset = ($page - 1) * $pagesize;
$sql = "select * from user limit $offset, $pagesize";
