Question

For example, a snippet of 50 characters. Problem is, of course, closing any opened tags. What’s a good way to do this? Or else to make things easier, what’s a good way to completely skim off all HTML content from the snippet?

Answer 1

If tags are generally allowed in the text (I mean, if, for example, text contains <b>, text must be marked with bold, etc), then looks like strip_tags() function is the easiest variant to remove tags from snippet.

If tags are generally not allowed in the text (for example, “<b>” must be just displayed as “<b>”), then you can use htmlentities() function.
