RE: [PHP] regexp question

How about: ereg('^[[:alnum:]_-]+$') See http://www.cs.utah.edu/dept/old/texinfo/regex/regex.html for an explanation of the [:alnum:]. For a quick intro to regexs see http://hotwired.lycos.com/webmonkey/97/33/index3a.html. For a more in-depth look, see: http://etext.lib.virginia.edu/helpsheets/regex.html http://www.perl.com/pub/doc/manual/html/pod/perlre.html And for a /really/ in-depth look at how these things work, see: http://www.oreilly.com/catalog/regex/chapter/ch04.html --Bruce Bruce Christensen Intel Corporation brucex.r.christensen@intel.com -----Original Message----- From: Ryan J Nichols [mailto:ryan@globali.net] Sent: Friday, August 11, 2000 11:43 AM To: php-general@lists.php.net Subject: [PHP] regexp question can I get a regexp that verifies a string is only 0-9 a-z A-Z or contains _ and - ereg("^[^A-Za-z0-9\d_-]+$",$bah) does not work. I've been toying with this for a while with no success, in addition to the answer a nice url to a tutorial on these things would be appreciated. Thanks in advance, Ryan
