I don't use ereg(i)? much myself but for a perl compat regex I would:
/^(([0-9a-z](\2*))\.([0-9a-z](\2*)))/i
the \# refer to parenthized matches starting at 1 and counting left parens.
The match array index you will want is $myArray[1].
if you don't mind matching
1a2.1a2 you can use
/^(([0-9a-z]+)\.\1+)/i
or
123.456
/^([0-9a-z]+\.[0-9a-z]+)/i
