How to Truncate a string in PHP to the word closest to a certain number of characters?
I have a string of keywords like below
word1, word3, word3, word4, word5
Now say this list is 400 chars long. I only want the keywords upto the 255 character but I also want to trim the last word as it may only be half a word.
Say I trim the keyword list and end up with this
word1, word3, word3, wo
How do I make sure I trim the last word only if it's half a word
Any ideas on this? I don't know where to start
By the way I'm using PHP
