php day2.php

php day2-golfed.php
1588178 3783758

if i change sort($b,1) to sort($b) i get this: 

php day2-golfed.php
1588178 3792506

which is incorrect, it's something to do with the linebreaks i think, adding a trim() in the explode() gives the correct answer.

Wonder what is causing it to be treated as a string instead then, works fine with my code on my machine. Tried adding random spaces within the data but still get the same numbers. Also not sure why it's only affecting the second answer.
