遇到會話變得非常煩人的問題。每次嘗試在特定頁面上啓動會話時,出現以下錯誤:消息:session_start():無法發送會話緩存限制器 - 已發送的頭文件
警告:session_start():無法發送會話緩存限制器 - 已發送的頭文件(輸出在/ home/uplbcdcn/public_html/CDC /警告:不能修改標題信息 - 已經發送的標題(在/ home/uplbcdcn /的public_html/CDC/admin_uplbcdc/header.php文件:57)在/home/uplbcdcn/public_html/CDC/admin_uplbcdc/index.php第42行
這裏是代碼:的header.php

在'<?php'標籤後面寫上'session_strat();'在頁面的頂部,並且在文件的最後一行刪除空行。 –
添加'session_start()'行開頭的文件。 –
