I'm using the following expression to check input strings: if (!ereg("^[[:alnum:]_-]+$", $string)) { get outta here! } This works fine except for when a string has spaces, as in text. What do I need to add to the expression to handle spaces (internal, not at the beginning or end).

if (!ereg("^[[:alnum:]_- ]+$", $string)) { get outta here! } Check out the regular expression documentation or "Mastering Regular Expressions" over at ora.com.

If by 'spaces' you want to include tabs, newlines & stuff, you can also do: if (!ereg("^[[:alnum:][:space:]_-]+$", $string)) { get outta here! } -steve -- +----------- 12 April 2001: Forty years of manned spaceflight -----------+ | Steve Edberg University of California, Davis | | sbedberg@ucdavis.edu Computer Consultant | | http://aesric.ucdavis.edu/ http://pgfsun.ucdavis.edu/ | +-------------------------- www.yurisnight.net --------------------------+
