我正在嘗試使用 Sendgrid 發(fā)送一封電子郵件，其中顯示了來(lái)自數(shù)據(jù)庫(kù)的信息。我的代碼：$email->addContent(    "text/html", "<?php foreach ($dueinsevendays as $dueinsevenday) :$sevendaycomref = $dueinsevenday['ceref'];$sevendaytitle = $dueinsevenday['cetitle'];$sevendaydate = $dueinsevenday['targetresponse'];$sevendaystage = $dueinsevenday['cestage'];?><tr>              <td style='border: 1px solid black;'>$sevendaycomref</td>      <td style='border: 1px solid black;'>$sevendaytitle</td>      <td style='border: 1px solid black;'>$sevendaydate</td>      <td style='border: 1px solid black;'>$sevendaystage</td>   </tr><?php endforeach; ?>")我在將查詢結(jié)果分配給變量時(shí)遇到錯(cuò)誤，例如它說(shuō)“$dueinsevenday['ceref'];”，第一個(gè) [ 顯示為錯(cuò)誤（語(yǔ)法錯(cuò)誤，意外的引用字符串和空格）。我需要為查詢返回的數(shù)據(jù)庫(kù)中的每條記錄創(chuàng)建一個(gè)表行，如果我在此 php 代碼之外分配變量，則沒(méi)有錯(cuò)誤但循環(huán)不起作用，此代碼將只顯示一個(gè)表行所有例如：$sevendaycomref = $dueinsevenday['ceref'];$sevendaytitle = $dueinsevenday['cetitle'];$sevendaydate = $dueinsevenday['targetresponse'];$sevendaystage = $dueinsevenday['cestage'];$email->addContent(    "text/html", "<?php foreach ($dueinsevendays as $dueinsevenday) :?><tr>              <td style='border: 1px solid black;'>$sevendaycomref</td>      <td style='border: 1px solid black;'>$sevendaytitle</td>      <td style='border: 1px solid black;'>$sevendaydate</td>      <td style='border: 1px solid black;'>$sevendaystage</td>   </tr><?php endforeach; ?>")任何關(guān)于如何修復(fù)錯(cuò)誤或重新排列代碼的想法都將受到高度贊賞。
