Hi,

Using the data structure, I need to remove duplicates using 'operation' and 'machine' keyword.

$data = [
          {
            'prod_order' => '702164',
            'operation' => '10',
            'machine' => 'W01',
            
          },
          {
            'prod_order' => '702164',
            'operation' => '10',
            'machine' => 'W02',
          },
            {
            'prod_order' => '702164',
            'operation' => '10',
            'machine' => 'W01',
          },
                {
            'prod_order' => '702164',
            'operation' => '10',
            'machine' => 'W02',
          },
            {
            'prod_order' => '702164',
            'operation' => '10',
            'machine' => 'W03',
          },
                {
            'prod_order' => '702164',
            'operation' => '100',
            'machine' => 'W03',
          }
          
        ];

Need to remove duplicates using 'operation' and 'machine' keyword. The ouput should be stored as follows

$data = [
          {
            'prod_order' => '702164',
            'operation' => '10',
            'machine' => 'W01',
            
          },
          {
            'prod_order' => '702164',
            'operation' => '10',
            'machine' => 'W02',
          },
            
            {
            'prod_order' => '702164',
            'operation' => '10',
            'machine' => 'W03',
          },
                {
