Bulk Insertion in Laravel using eloquent ORM

You can just use Eloquent::insert().

For example:

$data = [
    ['name'=>'Coder 1', 'rep'=>'4096'],
    ['name'=>'Coder 2', 'rep'=>'2048'],
    //...
];

Coder::insert($data);

We can update GTF answer to update timestamps easily

$data = array(
    array(
        'name'=>'Coder 1', 'rep'=>'4096',
        'created_at'=>date('Y-m-d H:i:s'),
        'modified_at'=> date('Y-m-d H:i:s')
       ),
    array(
         'name'=>'Coder 2', 'rep'=>'2048',
         'created_at'=>date('Y-m-d H:i:s'),
         'modified_at'=> date('Y-m-d H:i:s')
       ),
    //...
);

Coder::insert($data);

Update: to simplify the date we can use carbon as @Pedro Moreira suggested

$now = Carbon::now('utc')->toDateTimeString();
$data = array(
    array(
        'name'=>'Coder 1', 'rep'=>'4096',
        'created_at'=> $now,
        'modified_at'=> $now
       ),
    array(
         'name'=>'Coder 2', 'rep'=>'2048',
         'created_at'=> $now,
         'modified_at'=> $now
       ),
    //...
);

Coder::insert($data);

UPDATE2: for laravel 5 , use updated_at instead of modified_at

$now = Carbon::now('utc')->toDateTimeString();
$data = array(
    array(
        'name'=>'Coder 1', 'rep'=>'4096',
        'created_at'=> $now,
        'updated_at'=> $now
       ),
    array(
         'name'=>'Coder 2', 'rep'=>'2048',
         'created_at'=> $now,
         'updated_at'=> $now
       ),
    //...
);

Coder::insert($data);

This is how you do it in more Eloquent way,

    $allinterests = [];
    foreach($interests as $item){ // $interests array contains input data
        $interestcat = new User_Category();
        $interestcat->memberid = $item->memberid;
        $interestcat->catid = $item->catid;
        $allinterests[] = $interestcat->attributesToArray();
    }
    User_Category::insert($allinterests);
