(second try, should now also go the list)

Hi Anton,

please send such questions next time to the pear-general list, thanks.

There is no such file in the DataSource/ directory, but a file named
Array.php shoud exist there. Anyway, you don't need to include this file
yourself.

This won't work as you expect it to do. The right and better way is to
pass the options to the bind() call below. All options for the Array
DataSource driver can be found here:
http://pear.php.net/manual/en/packag...urce.array.php

Please note that the 'generate_columns' and 'labels' options are
deprecated. It's recommended to use $datagrid->generateColumns():
http://pear.php.net/manual/en/packag...atecolumns.php

This part is right.

Passing $_result to bind() should work here. Please remove the unneeded
lines from above, and try again. It's also a good idea to make sure that
there is a file named Array.php in the DataSource/ directory. (By using
the PEAR installer, this will be the case.)

Mark
