I am writing some regex on a php form to validate input and have come up
with this, for example -
if (empty($first) || !eregi("^[A-Za-z]+[- ]?[A-Za-z]+$", $first))
for checking a persons name. This allows a single name, or a hyphenated
double name, or a non-hyphenated double name, and it works. My question is
this - why is the third set followed by a '+' optional? I thought the +
meant the preceding group is present 1 or more times. The ? means the
preceding group is present 0 or more times. Why is it that when I put a ?
in the place of the + after the last ]
if (empty($first) || !eregi("^[A-Za-z]+[- ]?[A-Za-z]?$", $first))
the regex is broken?

Chip
