Laravel How to Make Array into a Collection?

Question

Good day everyone, I have this function that can generate time interval and store them to $time.

if(strtotime($startTime) <= strtotime($endTime))
        {
          $this->time[$i]['room'] = '49';
          $this->time[$i]['day'] = 'T-Th';
          $this->time[$i]['c_time'] = $start.'-'.$end;
          $this->time[$i]['sy'] = '2021-2022';
          $this->time[$i]['sem'] = '1st';
        }

Sample output of $time is like this

1 => array:5 [▼
    "room" => "49"
    "day" => "T-Th"
    "c_time" => "07:00-08:30"
    "sy" => "2021-2022"
    "sem" => "1st"
  ]
  2 => array:5 [▼
    "room" => "49"
    "day" => "T-Th"
    "c_time" => "08:30-10:00"
    "sy" => "2021-2022"
    "sem" => "1st"
  ]
  3 => array:5 [▼
    "room" => "49"
    "day" => "T-Th"
    "c_time" => "10:00-11:30"
    "sy" => "2021-2022"
    "sem" => "1st"
  ]]

What should I do so that the output would be a collection->toArray() just like this

array:5 [▼
  0 => {#1416 ▼
    +"room": "49"
    +"day": "M-W"
    +"c_time": "13:00-14:00"
    +"sy": "2021-2022"
    +"sem": "1st"
  }
  1 => {#1435 ▼
    +"room": "49"
    +"day": "M-W"
    +"c_time": "11:30-13:00"
    +"sy": "2021-2022"
    +"sem": "1st"
  }
  2 => {#1433 ▼
    +"room": "49"
    +"day": "M-W"
    +"c_time": "13:00-14:30"
    +"sy": "2021-2022"
    +"sem": "1st"
  }]

What have you tried so far? Where are you stuck? Why not generate a collection in the first place? — Nico Haase

Since you did not provide us with where you define the $time variable, I can't help you with any issues there. However, first, instantiate that variable as a collection.

$this->time = collect([]);

And then you can push in the following manner.

 $this->time->put($i, (object) [
    'room' => '49',
    'day' => 'T-Th',
    'c_time' => $start.'-'.$end,
    'sy' => '2021-2022',
    'sem' => '1st',
 ]);

can I ask something?

Nicklas Kevin Frank Over a year ago

You already did :) Go ahead.

Hahahha, from my question what the difference between the first array(top) and the second array(bottom)?

Nicklas Kevin Frank Over a year ago

@itsmejoe The first is an array of arrays, and the second is an array of objects. You need to push an object instead of an array to achieve that result.

Okay now I understand, so how should one create an array of objects?

The simplest way to convert an array to collection is to use Laravel's collect() helper function. It takes an array as a parameter and returns a collection type.

For example if we have this array:

$a = [
       ['name' => "abc", 'age' =>45],
       ['name' => "xyz", 'age' =>20],
     ];
        dd(collect($a));

The output will be:

Very good, but i would suggest to build the collection instead of building the array

itsme joe Over a year ago

Although I appreciate the answer but I am asking how do i construct the $time to return collection, because what i have done so far returns an array of arrays.
