您好，我是snikolov我正在使用PHP创建一个miniwebserver，我想知道我可以发送客户端要下载的文件与他的浏览器，如Firefox或Internet浏览我发送一个文件给用户通过套接字下载，但cleint没有得到文件名和信息下载可以请你帮我在这里，如果我再次声明文件我得到这个错误在我的服务器
致命错误 ：无法重新声明openfile（）（以前在C：\ User s \ fsfdsf \ sfdsfsdf \ httpd.php：31中声明） C：\用户\ hfghfgh \ hfghg \ httpd.php李 NE
，如果可能的话，我想知道，如果网络服务器能表现出多大的banwdidth通过套接字的用户请求，Perl有相同的选项作为PHP，但它的核心比PHP我更了解perl，我甚至看到miniwebserver可以显示很多客户端用户从服务器上拉出来，有可能你可以用这种编码来帮助我，我非常赞赏它谢谢家伙。

Answer 1

您没有将文件名发送给客户端，那么应该如何知道要使用哪个文件名？

有一个缺点，您可以在http标头中提供所需的文件名，但有些浏览器会忽略它，并始终根据URL中的最后一个元素提示文件名。 例如，http://localhost/download.php?help.me将导致文件下载对话框中的sugested文件名help.me。

每次你运行你的while (1)循环声明openfile功能。你只能声明一次函数。尝试在循环外移动openfile声明。
