我的代码出了问题（对不起它很多，但它是我知道的唯一方法，它基本上只是表中的一个select语句），它显示了一个页面链接，但没有改变页面结果。基本上我将它设置为例如每页1个结果，但它显示了所有结果，但仍显示顶部的链接转到下一页。下一页只显示相同的内容。我是一个PHP初学者，所以任何帮助都将非常感激。
谢谢！

问题在于，无论哪个页面当前处于“活动状态”，您总是获取相同的结果集，然后只输出所有结果集。如果你想分页，你可能想在SQL查询中使用类似LIMIT子句的东西（例如LIMIT 20,10来返回从偏移量20开始的10条记录（从零开始，即记录号21） ））。
答案 1 :(得分：1)
您需要做的是添加以下内容：
$ page = 1;
$ results_per_page = 10;
$ record_start =（$ page * $ results_per_page） - $ results_per_page;
$ result = mysql_query（“SELECT * FROM gj WHERE名称LIKE'％$ q％'或cat1 LIKE '％$ q％'或cat2 LIKE'％$ q'或cat3 LIKE '％$ q'按名称LIMIT排序 $ record_start，$ results_per_page“）或 trigger_error（mysql_error（））;
