Re: How can I split a string into chunks of 4 characters

[Lennotoecom]

$_ = '01234567890';

push @a, $1 while s/(.{1,4})//;

update
didn't read the task properly. my bad sorry
new solution:

$_ = '01234abc';

$_ = $2.$', push @a, $& while /(.)(.{3})/;

[davido]

"push @a, $1 while s/(.{1,4})//;" produces the following: "0123 4abc", which is not the desired result.

i will cite the author
"For example, string "01234abc" would become array 0123 4abc"
it is exactly what my script does
you sir, I suppose, didn't read the task
got mistaken. im sorry

From the OP:

For example, string "01234abc" would become array ("0123", "1234","234a","34ab","4abc")

Perhaps PetreAdi made an uncited alteration to the post, but the quoted example output data is what I remember seeing when I first read it.
