PHP和MySQL查詢

Question

我使用本教程Tracking Tool dispaly沒有顯示，我得到了它的工作。我試圖修改它以適應我的需求，跟蹤Verizon Wirless（我的手機連接），以監視他們何時開始扼殺我的IP更改。我的哥哥有AT & T，所以我在我的數據庫中添加了一個主機名字段，這樣我們就可以區分我們的手機......但可以讓它顯示在IP旁邊的報告頁面中。當我點擊視圖來顯示我訪問過的頁面時，我可以在那裏顯示它，但不在主頁面上，繼承我的代碼，如果任何人能夠指出爲什麼它不顯示或我改變了錯誤

只提注意到2貼被刪除......我「M不跟蹤任何人，但我自己,,,我已經在Verizon Wirless的一個植根霹靂,,,一次我打4演出的數據在一天（仍然有無限的計劃）verizon喜歡從一個IP啓動我，並將我切換到另一個更慢，我試圖指出哪些IP我注意到更好的帶寬，所以我可以循環收音機，直到它重新開始再好的一個

最後一行添加到您的報表腳本：

do{ 
    if($row["ip_total"] > 1) 
     $ip_list = "Multiple addresses"; 
    else 
     $ip_list = $row["ip_address_list"]; 

     // Add the following line here 
     $host = $row["hostname"];
