RE: [PHP] Trimming Text
Sounds like maybe he wants to keep his output to 25 chars not including HTML tags.. but wants to output tags if they're present. Turn this: This is regular text span class=textwith some text inside a span/span Into this: This is regular text with some text inside a span Then trim to: This is regular text withsnip Then output as: This is regular text span class=textwith/span In that case I'd do the following: 1. Use html_entity_decode and strip_tags to get just the text you want 2. Trim the text to the length you want 3. Somehow figure out where the HTML tags are in the original text and put them back, also use htmlentities to change any special characters back to entities. Someone might have a clever way of figuring out where the HTML tags are supposed to go back. I don't know of any quick and dirty way to do it off the top of my head. -TG = = = Original message = = = [snip] Let's say that I have an original string like: This is regular text span class=textwith some text inside a span/span Let's say I want to trim it to 25 chars.
