Php 打印结果以在多个页面上查看结果
我正在尝试创建一段代码，将我的查询结果限制在例如每页2个结果，其余的结果可以通过点击一个页码来查看，这与谷歌的搜索功能完全相同，因此如果我想要更多的结果，我只需进入第2页。如何使用PhP实现这一点。没有javascriptPhp 打印结果以在多个页面上查看结果,php,html,mysql,pdo,Php,Html,Mysql,Pdo,我正在尝试创建一段代码，将我的查询结果限制在例如每页2个结果，其余的结果可以通过点击一个页码来查看，这与谷歌的搜索功能完全相同，因此如果我想要更多的结果，我只需进入第2页。如何使用PhP实现这一点。没有javascript <!DOCTYPE html> <html> <head> <title>Database</title> <link href="style.css" rel="sty

请注意，虽然您在生产环境中使用准备好的语句是完全正确的，但我更喜欢在开发过程中避免使用这些语句，以便更容易响应发送到mysql的实际查询。在这种情况下，如果您理解了我的意思，如果我正确理解您的问题，您将如何使用$\u GET在同一页面上更改页面，您可以使用
$\u GET['page']$results\u per_page
