Hey everyone, I was noticing that there are a lot of ways that people are using to write their own string truncation functions wit the use of other functions like 'substr_replace', but it kinda seemed like a lot of them went a bit too far out to make any sense to a n00b. Not that I am one anymore, but I though I'd add a note on this topic myself, in hopes that it might help others understand things a little better.
Here's a concept that some people don't know about, or remember to use often enough; You can actually pull individual characters out of a string by referencing that string as though it were an array. Example: If I have the string $s = 'cat', I can use $s[0] to actually get out only the first character of that string, 'c'. I use that same principle below, but I just use a loop to iterate through a string and add the characters to the output variable one by one until the $lenth param has been reached, or until the end of the string.
I hope this can help someone out!
