Actually this text will be placed in meta description tag so I don't need any HTML in meta tag. How can I perform this? Any ideas and thoughts about this technique ?

Another option is to use Html2Text. It will do a much better job than strip_tags, especially if you want to parse complicated HTML code.
另一种选择是使用 Html2Text。它将比 strip_tags 做得更好，尤其是当您想解析复杂的 HTML 代码时。
Extracting text from HTML is tricky, so your best bet is to use a library built for this purpose.

Adding another option for someone else who may need this, the Stringizerlibrary might be an option, see Strip Tags.
为可能需要此功能的其他人添加另一个选项，Stringizer库可能是一个选项，请参阅Strip Tags。
