Trimming a block of text to the nearest word when a certain character limit is reached?

Question

Here is the question: How would your trim a block of text to the nearest word when a certain amount of characters have past. I\'m not trying to limit a certain number words

Answer 1

Wouldn't it be simpler to concat the strings using a place holder (i.e.: ###PLACEHOLDER###), count the chars of the string minus your place holder, trim it to the right length with substr and then explode by placeholder?
