2.1. Standard installation

Create a single directory for the OPL libraries code called "installation directory". Each OPL package contains an /lib folder whose must be copied to the installation directory.

In order to use OPL libraries in your project, you need to load the core file and register an autoloader:

require('../../lib/Opl/Base.php');
Opl_Loader::setDirectory('../../lib/');
Opl_Loader::register();
 
// use the libraries now

OPL uses exceptions to report problems and errors. It is recommended to capture them. The basic exception class used by the libraries is Opl_Exception, but each of the libraries provides also its own class. OPL contains also the default exception handler:

require('../../lib/Opl/Base.php');
Opl_Loader::setDirectory('../../lib/');
Opl_Loader::register();
 
try
{
    // your code
}
catch(Opl_Exception $exception)
{
    Opl_Error_Handler($exception);
}
