$arr = array(array('fg_type'=>'ECU1', 'item1'=>8810, 'rs1'=>5787788.527, 'item2'=>8928, 'rs2'=>5865309.4176),array('fg_type'=>'ECU1', 'item1'=>0, 'rs1'=>0, 'item2'=>0, 'rs2'=>0),array('fg_type'=>'ECU2', 'item1'=>63485, 'rs1'=>23211270.7503, 'item2'=>71973, 'rs2'=>26689668.0654),array('fg_type'=>'ECU2', 'item1'=>4810, 'rs1'=>2329072.60146, 'item2'=>5855, 'rs2'=>2783605.29921),array('fg_type'=>'ECU3', 'item1'=>1716, 'rs1'=>652004.847, 'item2'=>1711, 'rs2'=>647801.6757),array('fg_type'=>'ECU3', 'item1'=>0, 'rs1'=>0, 'item2'=>0, 'rs2'=>0),);$new_arr = array(); for($i=0; $i
 
  ';print_r($arr);
