用户名或电子邮件密码登录 PHPsession\u start（）只能在网页中的任何内容（即网页上的任何输出）被回显之前启动。下面是您正在使用不推荐的mysql.* 函数，因此在会话开始之前，您会收到错误消息。我建议您使用mysqli.* 或PDO 。目前，您可以使用以下方法关闭页面中的警告消息和错误消息： error_reporting(0); //or ini_set('display_errors', 0); 您需要将PHP配置为不呈现E_弃用通知，或修复弃用通知。您应该使用mysql客户端在会话启动之前，无法将任何输出发送回浏览器在php.ini中 error_reporting = E_ALL & ~E_DEPRECATED 或者在脚本中： ini_set("error_reporting", E_ALL & ~E_DEPRECATED); 我不知道该怎么做..请帮我一下好吗？在php页面的开头，放置这行代码ini\u set（'display\u errors'，0）这将阻止错误显示在您的网页上，然后会话将启动。我应该在每个网页上都这样做吗？是的，如果不想在您的每个网页上看到错误消息，但我不建议在开发页面上这样做，在实时版本上，您应该这样做。好的，我将尝试。但是会话启动时我的错误如何？如何修复它？如何将其转换为mysqli？我不知道。你能帮我把它转换一下吗。。
