Attach an application instance in your project:

When saving the data to the database, the mysql database will escape the special characters, which will be escaped when we read the data. In my project, we need to remove the HTML tag from the content in the n_info field first, then, the 60-character content is captured and displayed.

I thought it could be achieved by using strip_tags () directly. In actual use, it was found that the content in the database was escaped and strip_tags could not be identified, so we need to escape the special characters first,

Code: _ substr (strip_tags (htmlspecialchars_decode ($ value ['N _ info']), 0, 60)
