Question

I have string like this:

$str = "old iccid : 809831 3245 345 new iccid : 999000 112221"

How to remove the space character between number character in PHP, to become this output?

$output = "old iccid : 8098313245345 new iccid : 999000112221";

I’ve got the answer from xdazz (http://stackoverflow.com/users/762073/xdazz), this syntax works well.

$output = preg_replace('/(?<=\d)\s+(?=\d)/', '', $str);
