我知道的事實是，爲標題（位置）工作，沒有輸出必須發送之前。問題是我已經檢查了我的代碼很多次，但無法找到實際發送的內容，從而阻止了我的頭文件（位置）的工作。標題（位置）不工作
任何人都可以發現錯誤？

嘛，HTML堆之前發送，或者是不是？ – mario
「請記住，在發送任何實際輸出之前，必須調用header（），或者通過普通的HTML標籤，文件中的空行或PHP來發送。使用include或require函數來讀取代碼是一個非常常見的錯誤，或其他文件訪問函數，並且在調用header（）之前輸出空格或空行，使用單個PHP/HTML文件時也存在同樣的問題。「 手冊 – UnknownError1337
@mario過去有這樣的形式，我沒有遇到任何麻煩。或者你是什麼意思？ – Erik
