Split() takes a regex as the first argument.  The pipe character (|) is a 
special character in regex, so it needs to be escaped if you intend to use 
it as a string literal.

But, as noted in the docs 
http://www.php.net/manual/en/function.split.php: ...if you don't require 
the power of regular expressions, it is faster to use explode(), which 
doesn't incur the overhead of the regular expression engine.

For a split this simple, I'd recommend using explode(|, $data). split() 
uses a regex for the first character (and as others have said, the pipe is 
a metacharacter in a regex, so you'll need to use \| instead of |), 
whereas explode() is simply literal. explode() will probably be slightly 
faster, too, since it doesn't need to compile the regex, etc., although the 
difference will probably be infintesimal.
