For irregularity of files (created by users), i need to first make the file
content into a single line

preg_replace("/\n/", "", $data);

and then perform the matching.

however, i found the replacment fails. maybe that is due to microsoft
newline ^M instead of \n? if so, how to represent ^M in the pattern
matching? furthermore, the newline assumption may be wrong and how can i
know what the characters are there in the white spaces? I cannot use all
space characters since the data also contain spaces.

Thanks a lot.
