I'm beginning to think this may be the only solution.
I now have to figure out how to process the records as I'm looking for the
data in a particular line in the file, this should be fairly easy.
Thanks.

Try using fread() to get your file (it's binary safe). Then use:
explode(chr(0), $buffer);
to separate your fields.

Unfortunatly I get the message
"Warning: No ending delimiter '/' found in " when I try this. It appears
that PHP is interpreting the \0 as a string terminator for the pattern match
:(

Re: [PHP] Null character as field seperator in a string.
Hey..
yeah I might..
I don't know if I am right or just blabbering crap
but try to add these param's to your regex statement..
preg_split("/\0/i", $buffer);
note the i.. It should let it read past newlines.. although you're prob is
with null (\0) chars..
as I said.. Don't know if I am on the right track.. but it's worth a go eh??
good luck..
