The value of $string could include dashes or not. If it is, I'd like
the value of $foo to be set to the portion of the string to the left
of the first dash. If not, I'd like the value of $foo to be null.
I'm doing the following, but $foo is equal to "1" if there are no
dashes in the string:
$foo = (split('-',$string)),[0];
Can anyone tell me why this is happening?
