Depends on whether you want to modify the original
variable or not. You can remove anything with a
regex on the original:

     $phrase =~ s{ \s+ }{}gx;

will modify $phrase in place. You can also use a
regex on a copy or a join-and-split to make a new
copy of the variable:

     ( my $nospace = $phrase ) =~ s{ \s+ }{}gx;

or

     my $nospace = join '', split '', $phrase;

will give you a separate variable without the spaces.
