PHP, 1 (yes, one point!)
Using magic characters to generate a checksum, which in binary form matches "Hell", "o, w", "orld", and "! ".
Usually I like to find loopholes, but this time I decided to play by the spirit and intent of the contest. Every character and its position is essential to the output. The only places you can substitute are variable names which are not literal values, the whitespace between php and foreach which PHP treats as equivalent, and use of ' vs " which PHP treats as similar.
<?php foreach(array('_MC:`~+V4@SbHR/l[J','dN#UB`5!Rv^NG@D}','9gm6L&-kuD','8OM97g.q]XQ0')as$j)print(hash("crc32",$j,1))?>
FYI, these are some other magic strings and hashes of interest:
