意外的T_Variable错误，是什么导致它在循环？

Question

我妈收到一个错误，指出：

解析错误：语法错误，意想不到的T_VARIABLE ....线599

属于下面的一行：

foreach ($questions as $key=>$question) { 

    echo '<p><strong>Question:</strong> ' .htmlspecialchars($row_question['question_num'][$key]). ': ' .htmlspecialchars($row_question['question_content']$key]). '</p>' . PHP_EOL; 

    } 

我是什么做错了吗？

下面是代码：

$question = array(); 

    while ($selectedstudentanswerstmt->fetch()) { 

    $row_question = array(); 
    $row_question['question_num'] = $detailsQuestionNo; 
    $row_question['question_content'] = $detailsQuestionContent; 
    $row_question['question_option'] = $detailsOptionType; 
    $row_question['question_num_answers'] = $detailsNoofAnswers; 
    $row_question['question_answer'] = $detailsAnswer; 
    $row_question['questionnum_reply'] = $detailsReplyType; 
    $row_question['questionnum_marks'] = $detailsQuestionMarks; 
    $questions[] = $row_question; 
} 

................. 

<?php 

      foreach ($questions as $key=>$question) { 

echo '<p><strong>Question:</strong> ' .htmlspecialchars($row_question['question_num'][$key]). ': ' .htmlspecialchars($row_question['question_content']$key]). '</p>' . PHP_EOL; 

} 
?>

你缺少一个支架

echo '<p><strong>Question:</strong> ' .htmlspecialchars($row_question['question_num'][$key]). ': ' .htmlspecialchars($row_question['question_content']$key]). '</p>' . PHP_EOL; 

应该

echo '<p><strong>Question:</strong> ' .htmlspecialchars($row_question['question_num'][$key]). ': ' .htmlspecialchars($row_question['question_content'][$key]). '</p>' . PHP_EOL;
