您好，我是snikolov我正在使用PHP創建一個miniwebserver，我想知道我可以發送客戶端要下載的文件與他的瀏覽器，如Firefox或Internet瀏覽我發送一個文件給用戶通過套接字下載，但cleint沒有得到文件名和信息下載可以請你幫我在這裏，如果我再次聲明文件我得到這個錯誤在我的服務器
致命錯誤 ：無法重新聲明openfile（）（以前在C：\ User s \ fsfdsf \ sfdsfsdf \ httpd.php：31中聲明） C：\用戶\ hfghfgh \ hfghg \ httpd.php李 NE
，如果可能的話，我想知道，如果網絡服務器能表現出多大的banwdidth通過套接字的用戶請求，Perl有相同的選項作爲PHP，但它的核心比PHP我更瞭解perl，我甚至看到miniwebserver可以顯示很多客戶端用戶從服務器上拉出來，有可能你可以用這種編碼來幫助我，我非常讚賞它謝謝傢伙。

Answer 1

您沒有將文件名發送給客戶端，那麼應該如何知道要使用哪個文件名？

有一個缺點，您可以在http標頭中提供所需的文件名，但有些瀏覽器會忽略它，並始終根據URL中的最後一個元素提示文件名。 例如，http://localhost/download.php?help.me將導致文件下載對話框中的sugested文件名help.me。

每次你運行你的while (1)循環聲明openfile功能。你只能聲明一次函數。嘗試在循環外移動openfile聲明。
