显示错误
Parse error: syntax error, unexpected T_STRING, expecting ',' or ';' in D:\wamp1\www\blog\index.php on line 41
明明我写的是;却还是这个错误。。求解释

[解决办法]
echo "<div class="article">"; 41
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：

PHP code

// 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;
[解决办法]
echo "<div class="article">"; //41
echo "<div class="article_title"><p>$row['article_title']</p></div>";
echo "<div class="article_body"><p>$row['article_body']</p></div>";
echo "</div>";

改为
echo <<< HTML
<div class="article">
<div class="article_title"><p>$row[article_title]</p></div>
<div class="article_body"><p>$row[article_body]</p></div>
</div>
HTML;

既简单又清晰
切记！最后的 HTML; 要顶格
