php - 如何解析 HTML 中的信息 tag using php

Answer 1

It seems you have json inside the <code> tag.
So first (after you get the inner html of the <code> tag) get rid of the comments ('<!--', '-->') and then use function json_decode()

Answer 2

Take a look at PHP's strip_tags function: http://php.net/manual/en/function.strip-tags.php

This will at least remove the HTML entities from your string. You can also specify any HTML entities (tags, comments, etc.) that you want to keep, while removing everything else.
