我在使用PHP会话变量时遇到了一个新问题。问题是,它们似乎都能在Chrome和FireFox中工作,但在我的iPhone上不能在Safari中工作(注意:目前我无法访问本地页面用Internet Explorer进行测试,但我认为这超出了本问题的范围) 这是一个特别的问题,当我在一个网站上登录我正在工作的用户。代码如下: index.phpJavascript PHP会话变量未在Safari中设置,javascript,php,safari,session-variables,Javascript,Php,Safari,Session Variables,我在使用PHP会话变量时遇到了一个新问题。问题是,它们似乎都能在Chrome和FireFox中工作,但在我的iPhone上不能在Safari中工作(注意:目前我无法访问本地页面用Internet Explorer进行测试,但我认为这超出了本问题的范围) 这是一个特别的问题,当我在一个网站上登录我正在工作的用户。代码如下: index.php <?php session_start(); include ("dbconfig.php"); ?> <html> <he

你的具体问题是什么?会话变量似乎没有设置?您可能需要检查从浏览器获取的用户名和密码。浏览器对PHP代码的运行方式没有影响,因为它都是服务器端的,但它可以影响PHP脚本从浏览器获得的输入。浏览器不应该影响会话变量(因为它们是服务器生成的)。检查您的文档。cookie
并查看会话ID是否为sameYes,检查cookie。如果PHP设置为仅使用Cookie,Safari设置为拒绝来自站点的Cookie,那么这将很好地解释您的问题。大多数浏览器调试器都知道允许cookie检查。只需在FFox(Q或Firebug)或Chrome调试器中检查cookie,然后在Safari的调试器中检查cookie。因为您正在调试mobile Safari,所以
