How to create an array from a string?

[Francesco Moi]

Hello.

I would like to create an array from a string. I tried with:
---------------------------
$string = "1 2 3";
@array1 = [1,2,3];
@array2 = split(/\s/, $string);
print $array1[0] . " - " . $array1[1] . " - " . $array1[2] . "\n";
print $array2[0] . " - " . $array2[1] . " - " . $array2[2] . "\n";
---------------------------

But I get:
----------------------------
ARRAY(0x1674e9c) - -
1 - 2 - 3
-----------------------------

I would like to generate an array of the same type of 'array1' from
'string'. Is it possible?

Thank you very much.

------------^-----^

Hmm.. Don't you mean:

@array1 = (1,2,3);

That is a bad thing to want.

Luckily, that isn't really what you want.

You want to _populate_ an array from a string, not create an array.

Yes?


my @array1 = split /\s+/, "1 2 3";

There is more than one way to do it.....

If you want to use some form of literal to enumerate the values assigned to
elements of an array, you can do any of the following:

The list method:

my @array = ( 1, 2, 3 );


The string method:

my @array = split /\s+/, "1 2 3";

The list constructor operator method:

my @array = ( 1 .. 3 );

The word method:

my @array = qw(1 2 3);

There are others that deal with looping and such. But these ought to be
enough.

$string = "1 2 3";
@data = (['John','Peter','Sophie'], [split /\s/, $string]);

print "$data[0]->[0] - $data[0]->[1] - $data[0]->[2]\n";
print "$data[1]->[0] - $data[1]->[1] - $data[1]->[2]\n";

[ split /\s+/, "1 2 3" ]
