Basic markup

What follows is the simplest coding.

Example 1

<?php
namespace exampleproject;

use kaleidpixel\GeoIPAllow;

class JPIPAllow {
	/**
	 * @var GeoIPAllow
	 */
	protected $geoIpAllow = null;

	public function __construct( array $setting = [] ) {
		$setting['country'] = 'JP';

		if ( empty( $setting['output_path'] ) ) {
			$setting['output_path'] = dirname( __DIR__ ) . DIRECTORY_SEPARATOR . '.htaccess';
		}

		$this->geoIpAllow = new GeoIPAllow( $setting );
	}

	/**
	 * @param bool $echo
	 * @param bool $force
	 *
	 * @return void
	 */
	public function read( bool $echo = false, bool $force = false ): void {
		$this->geoIpAllow->read( $echo, $force );
	}
}

Example 2

<?php
require_once dirname( __DIR__ ) . DIRECTORY_SEPARATOR . 'vendor' . DIRECTORY_SEPARATOR . 'autoload.php';

use kaleidpixel\GeoIPAllow;

$now        = date( 'Y-m-d' );
$before_str = <<<EOL
## IP address of its In-House server.
Allow from 103.xxx.xxx.xxx
Allow from 203.xxx.xxx.xxx
EOL;

$ip = new GeoIPAllow(
	[
		'server'         => 'apache',
		'country'        => 'JP',
		'output_path'    => __DIR__ . DIRECTORY_SEPARATOR . '.htaccess',
		'add_before_str' => $before_str
	]
);

$ip->read(true);

The source code shown above will work on the built-in web server. It also operates in CLI, so choose whichever you prefer.

If you want to run it on the built-in web server, execute the command shown below and then access it with a web browser.

$ php -S localhost:8080

If you want to run it in CLI, execute the command shown below. The path where the file is outputted will be displayed as a result.
