我有这个例子分页代码,我一直在努力,我发现在另一个网站上。我终于用我的数据库和分页我的数据。但是,我不希望脚本列出页面的数量,只想显示“下一个”和“上一个”分页链接。我不出来,但也许你们中的一个可以:PHP:只保留下一个和上一个分页链接

    $tbl_name="posts";  //your table name 
    // How many adjacent pages should be shown on each side? 
    $adjacents = 3; 

    /* 
     First get total number of rows in data table. 
     If you have a WHERE clause in your query, make sure you mirror it here.

肮脏的,但应该做的工作,评论所有代码的//pages部分:
