获取foreach循环PHP中相同值的计数

Question

I have an array of repeated values of same column and different values of same column.So i'm trying get the one final array which can contains all the data.

Actual array:

array:4 [▼
  0 => {#820 ▼
    +"id": 318
    +"asset_id": 11
    +"job_id": 37
    +"asset_name": "Mini Paver"
    +"shift": "AM
  }
  1 => {#819 ▼
    +"id": 319
    +"asset_id": 39
    +"job_id": 37
    +"asset_name": "Road Sweeper"
    +"shift": "AM
  }
  2 => {#701 ▼
    +"id": 320
    +"asset_id": 11
    +"job_id": 37
    +"asset_name": "Mini Paver"
    +"shift": "AM
  }
  3 => {#825 ▼
    +"id": 321
    +"asset_id": 39
    +"job_id": 37
    +"asset_name": "Road Sweeper"
    +"shift": "AM

  }
]

and by using below for each loop I'm trying to get the one array out of four.

 $jobArr = array();
  foreach ($job_data as $data) {

            $jobArr[$data['job_id']]['job_id']       = $data->job_id;
            $jobArr[$data['job_id']]['shift']        = $data->shift;
            $jobArr[$data['job_id']]['asset_name'][] = $data->asset_name;

        }

and output for the above foreach is as below

array:1 [▼
  37 => array:8 [▼
    "job_id" => 37
    "shift" => "AM"
    "asset_name" => array:2 [▼
      0 => "Road Sweeper "
      1 => "Mini Paver "
    ]
  ]
]

Actually I need to get the count as well like how many asset names are there with the same name which should look like below

array:1 [▼
  37 => array:8 [▼
    "job_id" => 37
    "shift" => "AM"
    "asset_name" => array:2 [▼
      0 => "Road Sweeper (2)"
      1 => "Mini Paver (2)"
    ]
  ]
]

How do i get the count of same asset_name and the result array as like same above. Any suggestions please.

After you've built your grouped array as shown, you can iterate it and use array_count_values to generate an array in the new format, then replace the asset_name array with the new array.

foreach ($jobArr as $job_id => $job) {

    // iterate the counted values and build your array with the desired format
    foreach(array_count_values($job['asset_name']) as $asset => $count) {
        $counts[] = "$asset ($count)";
    }

    // replace the old asset_name key with your new counted/formatted array
    $jobArr[$job_id]['asset_name'] = $counts;
}
