在php中使用多維數組嵌套的foreach循環mysql mysql

Question

如果有人能夠幫助我，請幫助我，我真的不知道如何解決它，我一直在絞盡腦汁（和書籍和互聯網）有一段時間沒有真正理解我需要做什麼。我不是一個純粹自學的程序員，所以如果看起來容易，請接受我的道歉。我爲幻想聯盟足球網站創建了一個數據庫，並且已經獲得了結果和表格的正確查詢，我只想添加一個查詢，以顯示經理的每週結果，並從中得出哪些球員已經爲這些經理打分（沒有經理的團隊有相同的播放器），這樣一個例子：

（表頭：周>管理>有關>反對>射手） 2 Manager1 3-0（玩家1，玩家b 2） 2 Manager2 1-2（player f 1） 2 Manager3 4-1（player g 2，player x 2）

我使用大量連接來獲得我的結果，並且一直在試驗嵌套的foreach循環，我需要做一個單獨的foreach循環遍歷任何玩家每個進球得分的球隊（即從進球數大於0的球員名單中抽取），但結果好壞參半 - 我沒有任何需要的！

這裏是我的代碼，從索引控制器到顯示foreach循環的html。如果有人能夠幫助或有任何想法，我真的很感激。

首先，您有一個語法錯誤，可以通過查看Stackoverflow的語法高亮顯示來查看。你的第三行必須

include $_SERVER['DOCUMENT_ROOT'] . '/includes/db.inc.php'; 

經進一步審查，下面的線也是不正確的：

include $_SERVER['DOCUMENT_ROOT'] . /includes/error.html.php'; 

應該

include $_SERVER['DOCUMENT_ROOT'] . '/includes/error.html.php'; 

您需要封裝報價或內的所有字符串撇號。

我會推薦使用代碼編輯器，其中包括語言突出顯示爲您的語言，如KomodoEdit或Netbeans;你會節省很多頭痛。

如果這沒有幫助，請發佈您遇到的具體錯誤/問題。
