my php main:

// to the url parameter are added 4 parameters as described in colModel

// we should get these parameters to construct the needed query

// Since we specify in the options of the grid that we will use a GET method

// we should use the appropriate command to obtain the parameters.

// In our case this is $_GET. If we specify that we want to use post

// we should use $_POST. Maybe the better way is to use $_REQUEST, which

// contain both the GET and POST variables. For more information refer to php documentation.

// Get the requested page. By default grid sets this to 1.

$page = $_GET['page'];

// get how many rows we want to have into the grid - rowNum parameter in the grid

$limit = $_GET['rows'];

// after that the index from colModel
