That is _not_ what I *recommended*.  Please learn to quote.

Sounds like a CSV file, having <HT> as field delimiter and <CR><LF> as 
record delimiter.  Right?

If this is a CSV file and the fields contain a number each, not words, then 
I do not see how additional splitting at /\s+/ would help.  The fields 
should not contain white-space as they contain only one number each and are 
delimited by white-space, in particular <HT> ("\t").

Do you know <http://php.net/fgetcsv>?

You are welcome.  (But there should be no space before the `!' in English or 
German.)
