how split $string after 5 characters array

example:

$string="123456789";

expected output

$output[0] contain "12345"; $output[1] contain "6789";

if need split string after every 5 characters, try str_split():

$output = str_split($string, 5);

if need extract first 5 characters , put rest of string in second part of array, can use substr() nulluserexception suggests (code now-deleted answer):

$output[0] = substr($string, 0, 5); $output[1] = substr($string, 5);
