laravel foreach循环只存储db表中数组的最后一个元素

Question

i have function in my controller that uses php excel to read rows from excel file, and store it to db table.

public function processData(Request $request)
{
    /* store data from form in to variables */
    $hotel = $request->input('hotel');
    $date = $request->input('date');
    $start_row = $request->input('row');
    $date_col = $request->input('date-col');
    $sold_col = $request->input('sold-col');
    $rev_col = $request->input('rev-col');

    /* get tables name */
    $table = str_replace('-', '_', $hotel);
    $monthly_table = $table . '_monthly';

    /* init hotel class */
    $hotel_table = new Hotel($table);

    $file = public_path().'/'.$date.'.xls';

    $sheetData = Excel::load($file)->noHeading()->getExcel()->getSheet()->toArray(null,false,false, true);
    $sheetData = array_slice($sheetData, $start_row - 1);

    foreach ($sheetData as $row)
    {
        if ($this->isDate($row[$date_col]))
        {
            print $row[$date_col] . "---" . $row[$sold_col] . "---" . gettype(money_format('%i', floatval($row[$rev_col]))) . "<br>";
            $hotel_table->date = $row[$date_col];
            $hotel_table->sold = intval($row[$sold_col]);
            $hotel_table->sold_diff = 0;
            $hotel_table->rev = floatval($row[$rev_col]);
            $hotel_table->rev_diff = 0;
            $hotel_table->row = $start_row;
            $hotel_table->date_col = $date_col;
            $hotel_table->sold_col = $sold_col;
            $hotel_table->rev_col = $rev_col;
            //$hotel_table->save();
            if (!$hotel_table->save())
            {
                dd ( DB::getQueryLog() );
            }

        }
    }

}

public function isDate($date)
{
    if (date('m/d/Y', strtotime($date)) == $date)
    {
        return true;
    }
    else
    {
        return false;
    }
}

this is my table

Schema::create($tableName, function (Blueprint $table) {
            $table->increments('id');
            $table->string('date');
            $table->integer('sold');
            $table->integer('sold_diff');
            $table->float('rev');
            $table->float('rev_diff');
            $table->string('row');
            $table->string('date_col');
            $table->string('sold_col');
            $table->string('rev_col');
            $table->timestamps();
        });

when i go thru the foreach its printing things just fine to the screen there are no errors, but when i look at the table it only has last element of the array in db table.

If Hotel class is your model then you need to move following code inside foreach block

foreach ($sheetData as $row)
{
    if ($this->isDate($row[$date_col]))
    {           
       $hotel_table = new Hotel($table);
       ...
    }
}
