Well - after much experimentation, hair-pulling, and chasing of red herrings
I have discovered the error of my ways. :oD
Despite my 4 PHP reference books I eventually turned to the PHP Manual (in
.chm form) and it seems that the dba_open() function was modified for PHP
4.3.0 et seq, to include modifiers for the mode parameter, which handle
database locking, ie 'l', 'd', '-' and 't'.
So, the solution to my problem was nothing at all to to with file
permissions, security or sharing folders - it was DBA locking by default.
Along the way, some of you newbies may like know of a few other pit-falls:
1. Using db3 as the handler, rather than inifile or flatfile, it's
necessary to supply the _full_ path to your database file, rather than a
relative path (which actually works with the other handlers).
2. If the database parameter is supplied without a path (relative or
otherwise), a lock file is placed into the folder from which the script is
run, while the database file is planted squarely into the folder from which
php.exe is executed, in my case C:\PHP. Weird - took me a while to sus.
that one! (What about the setting of doc_root in php.ini? Makes no
difference.)
3. Use single, rather than double quotes for dba_open() parameters. In my
original test, I used double quotes (below) and, of course, \t was
interpolated!
Cheers,
Ian
