Question

我正在尝试将mySQL数据库中的HTML标签从纯文本中删除为SEO元描述。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>

我使用以下PHP格式化它：

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

这在网站的来源中显示以下内容：

<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（在这种情况下＆lt; p＆gt;）所以没有空格？

我理想地寻找Meta描述如下：

<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获取额外的空间吗？

非常感谢你的帮助。

Answer 1

您可以使用str_replace

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

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

Answer 2

尝试使用正则表达式。

$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.

Answer 3

试试这个：

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

注意preg_replace，将每个换行符更改为一个空格。

Answer 4

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对于任何打马的人来说都是至关重要的设备 - 正如Mary King所使用的那样。 Break-ezee是一种用于打马时的一体化进步训练产品。
