FYI, that code will also allow a string such as "99.4.3223...04..."
If that's not desirable, you could look into using the is_float() or
is_numeric() functions, or a regex such as:
if(preg_match('/^[0-9]*\.?[0-9]+$/',$string))
{ echo "good"; }
else
{ echo "bad"; }
That will allow text/numbers with or without a period.

eregi("^([0-9.])*$", $string)
will match:
an empty string
a string containing only 0-9 and periods
It is better for you to learn the preg_*() functions instead of the ereg*()
ones.
