我有一个带有分页概念的 php 页面，用于列出数据库中的项目并列出带有字母的项目。就像点击“a”一样，显示以字母“a”开头的名称，限制为 10 个，其余的应该出现在下一页。如果未选择字母表，则所有项目都显示分页。我试过了，但分页和类别列表是分开工作的。
$alpha='';
if(isset($_REQUEST['alphabet_let']))

$alpha=$_REQUEST['alphabet_let'];

$flag = $_REQUEST['flag'];

提前致谢。
最佳答案
你的 mysql 查询应该是这样的
SELECT * FROM `your_table` WHERE `column_name` LIKE '$your_query%' LIMIT 0 , 10
其中 0 是您的页码 -1。
