Hi yitzle, The reason to escape @ inside a double-quoted string is to prevent Perl from treating @example as an array.
# gives $id = "user1.com" since @example is empty $id = "[EMAIL PROTECTED]"; To prevent this, I believe it's better to use single quotes here $id = '[EMAIL PROTECTED]'; I agree with you that escaping . isn't necessary. However, unless we can be sure that the data we read in are properly formatted, escaping . won't hurt. m/[EMAIL PROTECTED]/ will match [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] cheers Higashi On 4/20/07, yitzle <[EMAIL PROTECTED]> wrote:
I fail to see the need to escape the @ and . A . needs to be escaped in RegEx to avoid confusion with the 'match any character', but otherwise, I don't think you want the slash there. On 4/20/07, Higashi Noboru <[EMAIL PROTECTED]> wrote: > try this > > $id = "[EMAIL PROTECTED]"; > > cheers
