Something like explode

[Anon]

Greetings,
Does anyone know of a way to essentially explode a string that has no separator character?
I'm trying to take a X character long string and either break it in to X new strings or an array with X entries. Is there any way to do this efficiently besides running a substr function for each place of the string?
Thanks,
Derek

you could try for example:

preg_match_all("/(.{5})/",$string,$array);

try to print_r($array[1]) - it'll contains strings, each 5 chars long.

$array=preg_split('',$string,PREG_SPLIT_NO_EMPTY);

will break an n-char string to an n-element array.
