First, there is no such thing as \- and even if there was you would have to write it as \\- because inside a double-quoted string in PHP escape chars are parsed. In order to get the eregi() function to see \- you would have to escape the \ and thus have \\-. That isn't you problem though. I quote from the Extended Regular Expression docs (see regex/regex.7 in the PHP distribution): To include a literal `]' in the list, make it the first character (following a possible `^'). To include a lit- eral `-', make it the first or last character, or the sec- ond endpoint of a range. To use a literal `-' as the first endpoint of a range, enclose it in [.' and .]' to make it a collating element (see below). With the excep- tion of these and some combinations using `[' (see next paragraphs), all other special characters, including `\', lose their special significance within a bracket expres- sion. So, this tells you that you cannot put a '-' in the middle of a range like that. I do not think this is a bug in PHP. PHP's behaviour is entirely consistent with that definition. ------------------------------------------------------------------------ [1998-10-20 17:17:33] markjr at easyDNS dot com eregi("[^a-z0-9\.\-]", "test-ing") returns false eregi("[^a-z0-9\-\.]", "test-ing") returns true Switching the escaped "." and "-" causes the pattern to fail erroneously. The behaviour goes away if you use an inclusive regex (read: lose the "^") here's a short script to test with <? function isValidAddr ($addr) { if(eregi("[^a-z0-9\-\.]",$addr)): return(false); else: return(true); endif; }; echo isValidAddr("Tesdt-jkjk") ? "true" : "false"; ?> ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=862&edit=1
