making an array out of a string or integer

Seshouan has asked for the wisdom of the Perl Monks concerning the following question:

is there a way to create an array out of a string or an integer? for example:

if I have $val = 238;
I want to get an array @arr that looks like the following:
$arr[0] = 2;
$arr[1] = 3;
$arr[2] = 8;

or the same thing for a string
if I have $val = "hello";
I want:
$arr[0] = "h";
$arr[1] = "e";
$arr[2] = "l";
$arr[3] = "l";
$arr[4] = "o";

thanks

Yes sure use split() `$val = 12345; @valary = split('', $val); foreach $item (@valary) { print $item,qq(\n); }` [download] The '' parameter in split() says split on nothing Hope that helps	[reply] [d/l]

`@arr = split //,$val;` perlfunc is your friend. rdfield	[reply] [d/l]

split(//,$val) will work. Remember, if you use it like a string it tends to behave like a string. -pete Entropy is not what is used to be.	[reply]
