Removing last character of a string

I had a string that looked like:
2;4;6;7;
The string is dynamic, so it could also be:
3;5;2;8;9;
I needed to remove the last ; (semicolon) from the string but wasn’t sure what the best method of doing this was. I thought about using the strlen() (string length) function. Get the value of how long the string is, and then removed the last character using substr(). The task seems a bit tedious and unefficient though.
So I searched Google to find the best method, and stumbled upon the answer to my question — How do you remove the last character of a string?
The solution is to use:
$outgoing = substr_replace($incoming,"",-1);
So if I use:
$outgoing = substr_replace('3;5;2;8;9;',"",-1);
My output would be:
3;5;2;8;9
Exactly what I was looking for! Thank you Graham Ellis!
