laravel drop multiple columns
// You may drop multiple columns from a table by passing an array of column
// names to the dropColumn method. Before dropping columns from a SQLite DB,
// you will need to add the doctrine/dbal dependency to your composer.json file
// and run the composer update command in your terminal to install the library:
Schema::table('users', function (Blueprint $table) {
$table->dropColumn(['votes', 'avatar', 'location']);
});
