Methods

public static base( [ mixed $protocol = NULL , boolean $index = bool FALSE ] ) (defined in Kohana_URL)

Gets the base URL to the application. To specify a protocol, provide the protocol as a string or request object. If a protocol is used, a complete URL will be generated using the $_SERVER['HTTP_HOST'] variable.

// Absolute URL path with no host or protocol
echo URL::base();

// Absolute URL path with host, https protocol and index.php if set
echo URL::base('https', TRUE);

// Absolute URL path with host and protocol from $request
echo URL::base($request);

Parameters

  • mixed $protocol = NULL - Protocol string, [Request], or boolean
  • boolean $index = bool FALSE - Add index file to URL?

Return Values

  • string

Source Code

public static function base($protocol = NULL, $index = FALSE)
{
	// Start with the configured base URL
	$base_url = Kohana::$base_url;

	if ($protocol === TRUE)
	{
		// Use the initial request to get the protocol
		$protocol = Request::$initial;
	}

	if ($protocol instanceof Request)
	{
		if ( ! $protocol->secure())
		{
			// Use the current protocol
			list($protocol) = explode('/', strtolower($protocol->protocol()));
		}
		else
		{
			$protocol = 'https';
		}
	}

	if ( ! $protocol)
	{
		// Use the configured default protocol
		$protocol = parse_url($base_url, PHP_URL_SCHEME);
	}

	if ($index === TRUE AND ! empty(Kohana::$index_file))
	{
		// Add the index file to the URL
		$base_url .= Kohana::$index_file.'/';
	}

	if (is_string($protocol))
	{
		if ($port = parse_url($base_url, PHP_URL_PORT))
		{
			// Found a port, make it usable for the URL
			$port = ':'.$port;
		}

		if ($domain = parse_url($base_url, PHP_URL_HOST))
		{
			// Remove everything but the path from the URL
			$base_url = parse_url($base_url, PHP_URL_PATH);
		}
		else
		{
			// Attempt to use HTTP_HOST and fallback to SERVER_NAME
			$domain = isset($_SERVER['HTTP_HOST']) ? $_SERVER['HTTP_HOST'] : $_SERVER['SERVER_NAME'];
		}

		// Add the protocol and domain to the base URL
		$base_url = $protocol.'://'.$domain.$port.$base_url;
	}

	return $base_url;
}

public static query( [ array $params = NULL , boolean $use_get = bool TRUE ] ) (defined in Kohana_URL)

Merges the current GET parameters with an array of new or overloaded parameters and returns the resulting query string.

// Returns "?sort=title&limit=10" combined with any existing GET values
$query = URL::query(array('sort' => 'title', 'limit' => 10));

Typically you would use this when you are sorting query results, or something similar.

Parameters with a NULL value are left out.

Parameters

  • array $params = NULL - Array of GET parameters
  • boolean $use_get = bool TRUE - Include current request GET parameters

Return Values

  • string

Source Code

public static function query(array $params = NULL, $use_get = TRUE)
{
	if ($use_get)
	{
		if ($params === NULL)
		{
			// Use only the current parameters
			$params = $_GET;
		}
		else
		{
			// Merge the current and new parameters
			$params = Arr::merge($_GET, $params);
		}
	}

	if (empty($params))
	{
		// No query parameters
		return '';
	}

	// Note: http_build_query returns an empty string for a params array with only NULL values
	$query = http_build_query($params, '', '&');

	// Don't prepend '?' to an empty string
	return ($query === '') ? '' : ('?'.$query);
}

public static site( [ string $uri = string(0) "" , mixed $protocol = NULL , boolean $index = bool TRUE ] ) (defined in Kohana_URL)

Fetches an absolute site URL based on a URI segment.

echo URL::site('foo/bar');

Parameters

  • string $uri = string(0) "" - Site URI to convert
  • mixed $protocol = NULL - Protocol string or [Request] class to use protocol from
  • boolean $index = bool TRUE - Include the index_page in the URL

Return Values

  • string

Source Code

public static function site($uri = '', $protocol = NULL, $index = TRUE)
{
	// Chop off possible scheme, host, port, user and pass parts
	$path = preg_replace('~^[-a-z0-9+.]++://[^/]++/?~', '', trim($uri, '/'));

	if ( ! UTF8::is_ascii($path))
	{
		// Encode all non-ASCII characters, as per RFC 1738
		$path = preg_replace_callback('~([^/]+)~', 'URL::_rawurlencode_callback', $path);
	}

	// Concat the URL
	return URL::base($protocol, $index).$path;
}

public static title( string $title [, string $separator = string(1) "-" , boolean $ascii_only = bool FALSE ] ) (defined in Kohana_URL)

Convert a phrase to a URL-safe title.

echo URL::title('My Blog Post'); // "my-blog-post"

Parameters

  • string $title required - Phrase to convert
  • string $separator = string(1) "-" - Word separator (any single character)

Return Values

  • string

Source Code

public static function title($title, $separator = '-', $ascii_only = FALSE)
{
	if ($ascii_only === TRUE)
	{
		// Transliterate non-ASCII characters

		// Remove all characters that are not the separator, a-z, 0-9, or whitespace
		$title = preg_replace('![^'.preg_quote($separator).'a-z0-9\s]+!', '', strtolower($title));
	}
	else
	{
		// Remove all characters that are not the separator, letters, numbers, or whitespace
		$title = preg_replace('![^'.preg_quote($separator).'\pL\pN\s]+!u', '', UTF8::strtolower($title));
	}

	// Replace all separator characters and whitespace by a single separator
	$title = preg_replace('!['.preg_quote($separator).'\s]+!u', $separator, $title);

	// Trim separators from the beginning and end
	return trim($title, $separator);
}
