SOLUTION

1) Make sure that PEAR is listed in the include_path in php.ini. To include dynamically the pear package use the following code substituting ‘pear_location’ with the actual location of your PEAR installation.

set_include_path(get_include_path() . PATH_SEPARATOR . ‘pear_location’);

2) Make sure that you have INSTALLED MDB2 and the driver for the database you are going to use. For example if you are working with MySQL then you need the MDB2_driver_mysql.

2.1.) To get information about all PEAR packages use the following command:

pear list

2.2.) To install a package use:

pear install packageName

2.3.) To upgrade a package use:

pear upgrade packageName

2.4.) Make sure that the dependence packages are upgraded also. To view the information about the package and its dependancies use:

pear info packageName

3) If you are developing under Windows make sure that the file name of your application is not called mdb2.php since it would be mixed up with the PEAR/MDB2.php file.
