我正在尝试将标签从 mySQL 数据库中的 HTML 剥离为 SEO 元描述的纯文本。数据库中的 HTML 如下所示：

<p>The Break-ezee is a vital piece of equipment for anyone when breaking horses - As used by Mary King.</p>
<p></p>
<p>The Break-ezee is an all in one progressive training product for use when breaking horses.</p>

我正在使用以下 PHP 对其进行格式化：

$showseodesc = trim(strip_tags(substr($showseoproduct['text'],0,160)));

这在网站的源代码中显示了以下内容：

<meta name="description" content="The Break-ezee is a vital piece of equipment for anyone when breaking horses - As used by Mary King.

The Break-ezee is an all in one progressi" />

无论如何我可以替换任何标签（在本例中为 <p>）所以没有空格？

理想情况下，我希望元描述看起来像这样：

<meta name="description" content="The Break-ezee is a vital piece of equipment for anyone when breaking horses - As used by Mary King. The Break-ezee is an all in one progressi" />

另外，我认为谷歌没有为元描述选择额外的空间是正确的吗？

非常感谢您的帮助。

你可以使用str_replace

$showseodesc = str_replace(array('<p>', '</p>'), '', $showseodesc);

$showseodec = substr($showseoproduct['text'],0, 160);

试试这个，使用正则表达式。

$string = "<p>The Break-ezee is a vital piece of equipment for anyone when breaking horses - As used by Mary King.</p>";

print preg_replace("|<[^>]+>|si","",$string); // <-- strip all tags from a string.

print preg_replace("|<p[^>]*>|si","",$string); // <-- strip all <p...> tags from a string.

尝试这个：

$showseodesc = trim(
                   preg_replace("/\n+/"," " , 
                               strip_tags(
                                         substr($showseoproduct['text'], 0, 160)
                                         )
                               )
                   );

请注意preg_replace，这会将每个换行符更改为一个空格。

str_replace 就足够了：-

$html = "<p>The Break-ezee is a vital piece of equipment for anyone when breaking horses - As used by Mary King.</p>
<p></p>
<p>The Break-ezee is an all in one progressive training product for use when breaking horses.</p>";

echo str_replace(array('<p>', '</p>'), '', $html);

输出：-

Break-ezee 是任何人在打破马匹时的重要装备 - 正如 Mary King 所使用的那样。Break-ezee 是一款多合一的渐进式训练产品，可在打破马匹时使用。
