AFAIK, you would need to know how many digits are there and use that
many capture groups (), because you only have one capture group which
will be overwritten each iteration. An alternative for your simple
example above would be to do:
preg_match('@a([0-9]+)b@' ,"a2345678b" , $matches);
--then--
print_r(str_split($matches[1]));
To do this multiple times in a large string you would need:
preg_match_all('@a([0-9]+)b@' ,"a2345678b" , $matches);
foreach($matches[1] as $match) {
print_r(str_split($match));
}
