Hi Andrew,
Latest version is available at http://adodb.sourceforge.net
thanks a lot for your help. Today we discovered what
our real problem was:
DB2 data driver. Requires ODBC.
After "playing" a little bit with the php-scripts that try
to connect to the IBM DB2, we set the optional parameter
Cursortype when calling odbc_pconnect(....).
From phpdb list:
And the exciting thing: When we set the cursor type
to SQL_CUR_USE_ODBC Cursor Type, then
the whole query speed up from 1 till 10 seconds
to 0.2 till 0.3 seconds for 100 records. Amazing!!!
Hi Andrew,
Therfore, PHP is just almost fast as calling the DB2
from Servlets using JDBC (don't take too much care
about the speed at whole: the database was on a
completely other location, so the whole connection
was made over a slow network connection).
thanks a lot for your help. Today we discovered what
our real problem was:
I hope this helps when other encounter the same
problem when trying to connect to DB2 from
PHP.

Mark Newnham has discovered that the SQL_CUR_USE_ODBC is not supported by
IBM's DB2 ODBC driver, so this must be a 3rd party ODBC driver.

SQL_ATTR_ODBC_CURSORS (DB2 CLI v5)
This connection attribute is defined by ODBC, but is not supported by DB2
CLI. Any attempt to set or get this attribute will result in an SQLSTATE of
HYC00 (Driver not capable).

A 32-bit option specifying how the Driver Manager uses the ODBC cursor
library.

Mark Newnham has discovered that the SQL_CUR_USE_ODBC is not supported by
IBM's DB2 ODBC driver, so this must be a 3rd party ODBC driver.
So I guess this means the message [above] was related to using a 3rd party
odbc driver.
From the IBM CLI Reference:
Setting SQL_CUR_USE_ODBC
========================
To set SQL_CUR_USE_ODBC for drivers that require it, do this:

$db->curMode = SQL_CUR_USE_ODBC;

System Error 5
==============
IF you get a System Error 5 when trying to Connect/Load, it could be a permission problem. Give the user connecting
to DB2 full rights to the DB2 SQLLIB directory, and place the user in the DBUSERS group.
