• Regex to Match White Space or End of String

  - by Kirk

  I'm trying to find every instance of @username in comment text and replace it with a link. Here's my PHP so far: $comment = preg_replace('/@(.+?)\s/', '<a href="/users/${1}/">@${1}</a> ', $comment); The only problem is the regex is dependent upon there being whitespace after the @username reference. Can anyone help me tweak this so it will also match if it is at the end of the string?

• $1 vs \1 in Perl regex substitutions

  - by Mr Foo Bar

  I'm debugging some code and wondered if there is any practical difference between $1 and \1 in Perl regex substitutions For example: my $package_name = "Some::Package::ButNotThis"; $package_name =~ s{^(\w+::\w+)}{$1}; print $package_name; # Some::Package This following line seems functionally equivalent: $package_name =~ s{^(\w+::w+)}{\1}; Are there subtle differences between these two statements? Do they behave differently in different versions of Perl?
