Easyui-datagri+checkbox How to use Getselections to save data to an array?

Checkboxeasyuiphpdatagrid

Easyui-datagrid, with a checkbox in it.

How do I save an array based on multiple rows of selected data sent to PHP, which is separated by PHP and subsequently executed for modification.

 function edit(){                  var row = $('#dg').datagrid('getSelections');                     for(var i = 0; i
   
   < code="">

只会用这种方法来获取uid，我应该怎么把他保存成数组。

 if($o == 'edit'){ $uid = $_GET['uid']; $profit_date = date('Y-m-d'); $sql = "update e_user set profit_date = '$profit_date' where uid='$uid'"; execute_data($sql);}

求指导。
