How can I store regex captures in an array in Perl?

Question

Is it possible to store all matches for a regular expression into an array?

I know I can use ($1,...,$n) = m/expr/g;, but it seems as though that can on

Answer 1

I think this is a self-explanatory example. Note /g modifier in the first regex:

$string = "one two three four";

@res = $string =~ m/(\w+)/g;
print Dumper(@res); # @res = ("one", "two", "three", "four")

@res = $string =~ m/(\w+) (\w+)/;
print Dumper(@res); # @res = ("one", "two")

Remember, you need to make sure the lvalue is in the list context, which means you have to surround scalar values with parenthesis:

($one, $two) = $string =~ m/(\w+) (\w+)/;
