HEREDOC回归意外结束

Question

以下片段引起了

"PHP Parse错误:语法错误,/ Applications/MAMP/htdocs3/nettuts/PHP/PDO for Database Access/htdocs/view_users02.php第39行意外结束"

我环顾了网站和谷歌,但没有找到确切的解决方案.

  foreach($DBH->query($sql) as $row){

        $output = "<tr><td align='left'>" . $row["name"] . "</td><td align='left'>" . $row["dr"] . "</td></tr>";


            // echo '<tr><td align="left">' . $row['name'] . '</td><td align="left">' . $row['dr'] . '</td></tr>';
     echo <<<EOT
            $output
    EOT;

完整的脚本

<?php 
$page_title = 'View the Current Users';
include ('includes/header.html');

// Page header:
echo '<h1>Registered Users</h1>';

require_once ('../mysql_pdo_connect.php'); // Connect to the db.

// Make the query:

$sql = "SELECT CONCAT(last_name, ', ', first_name) AS name, DATE_FORMAT(registration_date, '%M %d, %Y') AS dr FROM users ORDER BY registration_date ASC";   

    // Table header.
    echo <<<EOT
    <table align='center' cellspacing='3' cellpadding='3' width='75%'>
    <tr><td align='left'><b>Name</b></td><td align='left'><b>Date Registered</b></td></tr>
EOT;


foreach($DBH->query($sql) as $row){

    $output = "<tr><td align='left'>" . $row["name"] . "</td><td align='left'>" . $row["dr"] . "</td></tr>";


        // echo '<tr><td align="left">' . $row['name'] . '</td><td align="left">' . $row['dr'] . '</td></tr>';
 echo <<<EOT
        $output
EOT;         

        }

    echo '</table>'; // Close the table.
    $DBH = null;


include ('includes/footer.html');
?>

Answer 1

EOT;在循环之后你有一大堆空格(确切地说是9个).

从手册

...在分号之前或之后可能没有任何空格或制表符......

为什么要将$output变量包装在HEREDOC字符串中？我只是将循环更改为

printf('<tr><td align="left">%s</td><td align="left">%s</td></tr>',
       htmlspecialchars($row["name"]),
       htmlspecialchars($row["dr"]));

甚至更好,使用PHP的替代语法.
