Re: note 9349 added to ereg

Meta-characters inside a bracket expression definition do not have special meaning, except from "^" or "-", i.e. the "." does not need to be escaped inside "[-_.]" Run the code below, and you'll see what I mean: $r1 = "[-_.]"; $r2 = "[-_\.]"; $s1 = "to match r1 and r2 . - _"; $s2 = "to match only \ r2"; echo (int) ereg($r1,$s1)."\n"; echo (int) ereg($r2,$s1)."\n"; echo (int) ereg($r1,$s2)."\n"; echo (int) ereg($r2,$s2)."\n"; It will print out: 1 1 0 1 Check your regex(7) man page, and read "Mastering Regular Expressions" it is a great source for all things regex. Your note will be removed. --- aah@acm.org wrote: > More on email validity checking: I may be wrong, > but it seems to me that all the tests above fail to > properly escape the '.' character within the > address.
