Easier process to define multiple similar callback functions

    I’m sorry, this is more of a PHP language question, but I hope I’ll get help.

    I have a settings panel in which I have 12 similar functions, which just replace month name at 2-3 places. I didn’t want to define 12 callback functions, so I tried this and haven’t been able to get it to work.

    function display_festivals_fields() {
	add_settings_section("section", "All Settings", null, "manage-festivals");

	$months = array(
		'january','february','march','april','may','june','july','august','september','october','november','december'
	);

	foreach($months as $month) {
		add_settings_field("festivals_{$month}", ucwords($month) . " Festivals", function() use ($month) { echo "<textarea type='text' name=\"{$month}_festivals\" id=\"{$month}_festivals\" value='".get_option("{$month}_festivals")."' ></textarea>";}, "manage-festivals", "section");
		register_setting("section", "festivals_{$month}");
	}
}

    It was a silly mistake. I jumbled up option name and forgot that textarea doesn’t use value attribute.

    function display_festivals_fields() {
	add_settings_section( "section", "All Settings", null, "manage-festivals" );

	$months = [
		'january',
		'february',
		'march',
		'april',
		'may',
		'june',
		'july',
		'august',
		'september',
		'october',
		'november',
		'december',
	];

	foreach ( $months as $month ) {
		add_settings_field(
			"festivals_{$month}",
			ucwords( $month ) . " Festivals",
			function () use ( $month ) { echo "<textarea type='text' name=\"festivals_{$month}\" id=\"festivals_{$month}\">" . get_option( "festivals_{$month}" ) . "</textarea>"; },
			"manage-festivals",
			"section"
		);
		register_setting( "section", "festivals_{$month}" );
	}
}
