perl - Test whether one string contains any of the words in another -


i have perl program code pulls description string hash.

i have variable $ui equal variable $uniqueid, want return true if $ui contains words in variable $unqiueid. =~ isn't working.

is there smart way of doing this?

sub getdescription {      $uniqueid = shift;     $retval;     $ui;      foreach $key ( keys %hashlist ) {          foreach $ui ( @{ $hashlist{$key}->{uniqueid} }) {              if ( $ui eq $uniqueid ) {                 $retval = $hashlist{$key}->{description};                 last;             }          }           last if $retval;     }      return $retval; }

a simple way test if 1 scalar variable contains is:

if ($ui =~ /$uniqueid/) {     ... }

(and @markus laire points out can use /\b$uniqueid\b/ prevent partial word matches.)
