您的正则表达式应该如下所示：
/<h6>([^<]+)<\/h6>([^<]+)/im如果运行以下脚本，您将看到正在查找的值位于$matches1和$matches2中。
$s = "<h6>First pane</h6>
... pane content ...
<h6>Second pane</h6>

$r = "/<h6>([^<]+)<\/h6>([^<]+)/im";
$matches = array();
preg_match_all($r,$s,$matches);

您不应该尝试使用正则表达式来解析HTML。这注定会给除了最简单的HTML之外的所有人带来很多痛苦和不快，并且如果文档结构中有任何变化，它将立即崩溃。使用合适的超文本标记语言或DOM解析器，如php的DOMDocument http://php.net/manual/en/class.domdocument.php
