这错误没看出来？ echo "<div class="到这儿就算字符串完了，后面本应该就是分号，但这儿却是字符串article。
还不明白？正确的做法是对字符串中的双引号用\"转义
以下写法都算正确：
// 转义双引号
echo "<div class=\"article\">";
// 改用单引号，防止与字符串内的双引号冲突
echo '<div class="article">';
// 方便一点的，改用
echo <<<html
<div class="article">
html;手册说明： http://www.php.net/manual/zh/language.types.string.php
echo '<div class="article_title"><p>'.$row['article_title'].'</p></div>';
echo '<div class="article_body"><p>'.$row['article_body'].'</p></div>';
echo '</div>';
echo "<div class=\"article_title\"><p>$row['article_title']</p></div>";
echo "<div class=\"article_body\"><p>$row['article_body']</p></div>";
echo "</div>";为什么我这样转义后显示 错误
Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in D:\wamp1\www\blog\index.php on line 42
echo "<div class=\"article_body\"><p>{$row['article_body']}</p></div>";
字符串中包含变量最好用 {}括起来，尤其是数组
echo '<div class=\"article_title\"><p>.'$row['article_title']'.</p></div>';
echo '<div class=\"article_body\"><p>.'$row['article_body']'.</p></div>';
echo '</div>';
这样显示还是错啊？？
