laravel migrations nullable code example

Example 1: laravel migration make column nullable

Schema::table('users', function($table)
{
    $table->string('name', 50)->nullable()->change();
});

This is the correct syntax to revert the migration:

$table->integer('user_id')->unsigned()->nullable(false)->change();

Example 2: laravel change column

Schema::table('users', function (Blueprint $table) {
    $table->string('name', 50)->nullable()->change();
});

Example 3: integer nullable laravel

$table->integer('banner_id')->nullable()->unsigned();
