Fill array with zero values in a a given range

Question

I am working on laravel 5.3 and Here is my code

$arrayData = array();
foreach ($stats as $key => $row) {
      $arrayData[] = array(
      'number'   => $row->no,
      'level'    => $row->total_sent,
      'past'     => $row->past,
  );
}

if i dd($arrayData) its output is as

array:3 [▼
  0 => array:3 [▼
    "no" => "4"
    "level" => 3
    "past" => "3"
  ]
  1 => array:3 [▼
    "no" => "6"
    "level" => 3
    "past" => "3"
  ]
  2 => array:3 [▼
    "no" => "9"
    "level" => 3
    "past" => "3"
  ]
]

Here in above no are 4,6,9 respectively. I want final out output should contain complete data. If no exits that's fine other wise numbers should be with zero.

In above case, desired output is as at missing position there will be a correct number with zero values

array:11 [▼
  0 => array:3 [▼
    "no" => "0"
    "level" => 0
    "past" => "0"
  ]
  1 => array:3 [▼
    "no" => "1"
    "level" => 0
    "past" => "0"
  ]
  2 => array:3 [▼
    "no" => "2"
    "level" => 0
    "past" => "0"
  ]
  3 => array:3 [▼
    "no" => "3"
    "level" => 0
    "past" => "0"
  ]
  4 => array:3 [▼
    "no" => "4"
    "level" => 3
    "past" => "3"
  ]
  5 => array:3 [▼
    "no" => "5"
    "level" => 0
    "past" => "0"
  ]
  6 => array:3 [▼
    "no" => "6"
    "level" => 3
    "past" => "3"
  ]
  7 => array:3 [▼
    "no" => "7"
    "level" => 0
    "past" => "0"
  ]
  8 => array:3 [▼
    "no" => "8"
    "level" => 0
    "past" => "0"
  ]
  9 => array:3 [▼
    "no" => "9"
    "level" => 3
    "past" => "3"
  ]
  10 => array:3 [▼
    "no" => "10"
    "level" => 0
    "past" => "0"
  ]

Hope Question is clear

Thanks in advance

Answer 1

Initiate array with zero-filled values:

for ($i=0; $i <= 10; $i++) {
    $arrayData[$i] = [
        "no" => "$i",
        "level" => 0,
        "past" => "0",
    ];
}
foreach ($stats as $key => $row) {
    $arrayData[$row->no] = [
        'no' => $row->no,
        'level' => $row->total_sent,
        'past' => $row->past,
    ];
}

If you do not know max no value, you need to get it. Then fill $arrayData with zero elements using array_fill function

$stats = collect($stats);
$arrayData = [];

$maxNo = $stats->max('no');

$arrayData = array_fill(0, $maxNo, [
    'number' => 0,
    'level' => 0,
    'past' => 0
]);

$stats->each(function($row) use(&$arrayData){
    $arrayData[$row->no] = [
        'number'   => $row->no,
        'level'    => $row->total_sent,
        'past'     => $row->past,
    ];
});
