Laravel migrations change default value of column

You can use change() method:

Schema::table('users', function ($table) {
    $table->integer('active')->default(0)->change();
});

Then run migrate command.

Update

For Laravel 4 use something like this:

DB::statement('ALTER TABLE `users` CHANGE COLUMN `active` `active` INTEGER NOT NULL DEFAULT 0;');

Inside up() method instead of Schema::table(); clause.

You have to call the change function to update the column

if (Schema::hasTable('users')) {
    Schema::table('users', function (Blueprint $table) {
        if (Schema::hasColumn('users', 'active')) {
            $table->integer('active')->default(0)->change();
        }
    });
}
