The application needs to split the string into triplets, then split the triplet into numbers. In C, this would take up about 480K (20000 times 3 x 8 bytes) for the final array. The intermediate array of strings shouldnt be much bigger than the long string itself (1MB). And I expect some overhead from PHP, say 300% to allow for indexes etc.
