嘗試在php中編寫嵌入式SQL。 無法找出此語法錯誤
[英]Trying to write an embedded sql in php. can't figure out this syntax error
問題描述
我在屏幕后面坐了一段時間，試圖修復此代碼。 每當我運行它時，我都會得到一個語法錯誤，指示代碼的最后一行。 我想做的是編寫一個基於Web的數據庫，可以在其中添加，更新，刪除和檢索數據庫中的信息。
<head>
<title></title>
<script src="prototype.js" type="text/javascript"></script>
<script type="text/javascript"></script>

您的if($sel=="update"){可能缺少右括號。
編輯：實際上，進一步查看您的代碼，似乎您缺少很多右括號。 我建議您離顯示器5分鍾的路程來清理自己的頭，然后回來，您會看到它們全部向您跳來跳去。
無法在寫上下文中使用函數返回值，PHP無法弄清原因
