Thanks for the heads up on fgetc() incrementing by one. I hadn't actually
tested that code yet, I was using the original fseek($handle,$pos).
strpos would be ideal but it needs to work on a string and not a file - I
don't want to load a 100Mb file into memory if I don't have to. Perhaps I

So the only variation on a theme that I didn't test is the one that performs
the best by an order of magnitude... nice. Many thanks for your time

function just for this purpose, which hardly seems worth it.
Thanks to anyone who takes the time to think about my question and/or

Hi Rahul,
Try doing a print_r($_SERVER) to see if the variables are being set.
If they aren't, take a look at the phpinfo(); - chances are your host is
using a CGI binary version of PHP to use together with a security wrapper
like suPHP or phpSuExec, which might throw away the variables that
Hi,
David is right about the unwanted side-effect. Thanks for the idea though.
Unfortunately the 'greater problem' is not so great, I've just been doing

and I've never got round to testing if a simple IF statement is a

I think you'll find that your first approach is not only more correct,
it's the only manageable one.
No, it will be very slow. The biggest overhead is in transfering data to
and from sql server. It's always better to get the results in one sql
