PHP APIs for Distributed Mode

In the .php source code, include the following:

$greRunnerObj = new GreRunner($reportDesignFileName, $reportClassName);
$greRunnerObj->configureDistributedProcessing("GRE_server_name",port);

• GRE_server_name is the name of the server where the GRE is running.
• port is the port number where the GRE is listening.
