Mac Os 10.6.5中Safari上的PHP/HTML运行速度非常慢

以下是脚本：

<?php

            if ($_POST['name'] == "") {
                $errors .= 'Please enter a valid name.<br/><br/>';
            }
        } else {

所有这些都可以在带有任何浏览器的Windows上正常工作，在iPhone和iPad上也可以正常工作。 问题似乎出在Mac上。 该脚本执行速度非常慢，并从错误的电子邮件地址向用户发送“感谢”信。 另外，Mac上的谷歌浏览器似乎也有同样的问题

你认为可能是什么

谢谢大家!

执行时间与浏览器无关php是一种服务器端语言

您应该通过回显脚本中的各种变量来调试代码，并检查它们是否具有假定的值，如果没有，您可以查看之前的代码，在那里回显变量，以找出可能出现的错误

您的意思是在Mac上运行的此脚本执行缓慢，还是在Mac 10.6.5上的Safari上无法运行该页面？服务器是否在本地Mac上运行用于开发？如果是，这将增加可能的瓶颈列表。如果不是这样，那么解决方案将更容易找到：-）只需使用xdebug并分析您的脚本。（否则，我的猜测是，速度慢是因为您使用了XHTML语法，但没有使用XHTML mime类型。）我猜，它在Mac 10.6.5上的任何Safari上都运行缓慢。我不认为我的客户去了一家苹果商店，在那里的几台电脑上进行了测试。
