Function to count "commas

What is function in PHP to count how many commas are there in String?

Im sure there is a better way but this would work:

PHP Code:

---

$count = count(explode(",",$string))-1; 


---

substr_count() would seem to be the simplest way. (PHP has lots of string functions, so that's always a good place to start. ;) )

Thanks! It worked!
