使用Laravel php artisan命令将数据库表导出为CSV

Question

I'm writing a artisan command to export the table from my database as a csv file. But when im running the command, the CLI shows me only the data from the database and don't create a CSV File.

Answer 1

this works fine in my laravel 5.4 project

public function handle()
{
    $filename = "logins.csv";

    $handle = fopen($filename, 'w');
    fputcsv($handle, array('customer_id', 'count', 'year', 'month', 'day', 'hour'));

    fputcsv($handle, array("row['customer_id']", "row['count']", "row['year']", "row['month']", "row['day']", "row['hour']"));

    fclose($handle);

    $headers = array(
        'Content-Type' => 'text/csv',
    );
}

creates file logins.csv in the project root directory

customer_id,count,year,month,day,hour
row['customer_id'],row['count'],row['year'],row['month'],row['day'],row['hour']

btw what is purpose of $headers array ?

CLI shows me only the data from the database

maybe you have dd() somewhere?
