-URI Class
-#########
-
-The URI Class provides methods that help you retrieve information from
-your URI strings. If you use URI routing, you can also retrieve
-information about the re-routed segments.
-
-.. note:: This class is initialized automatically by the system so there
-	is no need to do it manually.

-Class Reference
-***************
-
-.. php:class:: CI_URI
-
-	.. php:method:: segment($n[, $no_result = NULL])
-
-		:param	int	$n: Segment index number
-		:param	mixed	$no_result: What to return if the searched segment is not found
-		:returns:	Segment value or $no_result value if not found
-		:rtype:	mixed
-
-		Permits you to retrieve a specific segment. Where n is the segment
-		number you wish to retrieve. Segments are numbered from left to right.
-		For example, if your full URL is this::
-
-			http://example.com/index.php/news/local/metro/crime_is_up
-
-		The segment numbers would be this:
-
-		#. news
-		#. local
-		#. metro
-		#. crime_is_up
-
-		The optional second parameter defaults to NULL and allows you to set the return value
-		of this method when the requested URI segment is missing.
-		For example, this would tell the method to return the number zero in the event of failure::
-
-			$product_id = $this->uri->segment(3, 0);
-
-		It helps avoid having to write code like this::
-
-			if ($this->uri->segment(3) === FALSE)
-			{
-				$product_id = 0;
-			}
-			else
-			{
-				$product_id = $this->uri->segment(3);
-			}
-
-	.. php:method:: rsegment($n[, $no_result = NULL])
-
-		:param	int	$n: Segment index number
-		:param	mixed	$no_result: What to return if the searched segment is not found
-		:returns:	Routed segment value or $no_result value if not found
-		:rtype:	mixed
-
-		This method is identical to ``segment()``, except that it lets you retrieve
-		a specific segment from your re-routed URI in the event you are
-		using CodeIgniter's :doc:`URI Routing <../general/routing>` feature.
-
-	.. php:method:: slash_segment($n[, $where = 'trailing'])
-
-		:param	int	$n: Segment index number
-		:param	string	$where: Where to add the slash ('trailing' or 'leading')
-		:returns:	Segment value, prepended/suffixed with a forward slash, or a slash if not found
-		:rtype:	string
-
-		This method is almost identical to ``segment()``, except it
-		adds a trailing and/or leading slash based on the second parameter.
-		If the parameter is not used, a trailing slash added. Examples::
-
-			$this->uri->slash_segment(3);
-			$this->uri->slash_segment(3, 'leading');
-			$this->uri->slash_segment(3, 'both');
-
-		Returns:
-
-		#. segment/
-		#. /segment
-		#. /segment/
-
-	.. php:method:: slash_rsegment($n[, $where = 'trailing'])
-
-		:param	int	$n: Segment index number
-		:param	string	$where: Where to add the slash ('trailing' or 'leading')
-		:returns:	Routed segment value, prepended/suffixed with a forward slash, or a slash if not found
-		:rtype:	string
-
-		This method is identical to ``slash_segment()``, except that it lets you
-		add slashes a specific segment from your re-routed URI in the event you
-		are using CodeIgniter's :doc:`URI Routing <../general/routing>`
-		feature.
-
-	.. php:method:: uri_to_assoc([$n = 3[, $default = array()]])
-
-		:param	int	$n: Segment index number
-		:param	array	$default: Default values
-		:returns:	Associative URI segments array
-		:rtype:	array
-
-		This method lets you turn URI segments into an associative array of
-		key/value pairs. Consider this URI::
-
-			index.php/user/search/name/joe/location/UK/gender/male
-
-		Using this method you can turn the URI into an associative array with
-		this prototype::
-
-			[array]
-			(
-				'name'		=> 'joe'
-				'location'	=> 'UK'
-				'gender'	=> 'male'
-			)
-
-		The first parameter lets you set an offset, which defaults to 3 since your
-		URI will normally contain a controller/method pair in the first and second segments.
-		Example::
-
-			$array = $this->uri->uri_to_assoc(3);
-			echo $array['name'];
-
-		The second parameter lets you set default key names, so that the array
-		returned will always contain expected indexes, even if missing from the URI.
-		Example::
-
-			$default = array('name', 'gender', 'location', 'type', 'sort');
-			$array = $this->uri->uri_to_assoc(3, $default);
-
-		If the URI does not contain a value in your default, an array index will
-		be set to that name, with a value of NULL.
-
-		Lastly, if a corresponding value is not found for a given key (if there
-		is an odd number of URI segments) the value will be set to NULL.
-
-	.. php:method:: ruri_to_assoc([$n = 3[, $default = array()]])
-
-		:param	int	$n: Segment index number
-		:param	array	$default: Default values
-		:returns:	Associative routed URI segments array
-		:rtype:	array
-
-		This method is identical to ``uri_to_assoc()``, except that it creates
-		an associative array using the re-routed URI in the event you are using
-		CodeIgniter's :doc:`URI Routing <../general/routing>` feature.
-
-	.. php:method:: assoc_to_uri($array)
-
-		:param	array	$array: Input array of key/value pairs
-		:returns:	URI string
-		:rtype:	string
-
-		Takes an associative array as input and generates a URI string from it.
-		The array keys will be included in the string. Example::
-
-			$array = array('product' => 'shoes', 'size' => 'large', 'color' => 'red');
-			$str = $this->uri->assoc_to_uri($array);
-
-			// Produces: product/shoes/size/large/color/red
-
-	.. php:method:: uri_string()
-
-		:returns:	URI string
-		:rtype:	string
-
-		Returns a string with the complete URI. For example, if this is your full URL::
-
-			http://example.com/index.php/news/local/345
-
-		The method would return this::
-
-			news/local/345
-
-	.. php:method:: ruri_string()
-
-		:returns:	Routed URI string
-		:rtype:	string
-
-		This method is identical to ``uri_string()``, except that it returns
-		the re-routed URI in the event you are using CodeIgniter's :doc:`URI
-		Routing <../general/routing>` feature.
-
-	.. php:method:: total_segments()
-
-		:returns:	Count of URI segments
-		:rtype:	int
-
-		Returns the total number of segments.
-
-	.. php:method:: total_rsegments()
-
-		:returns:	Count of routed URI segments
-		:rtype:	int
-
-		This method is identical to ``total_segments()``, except that it returns
-		the total number of segments in your re-routed URI in the event you are
-		using CodeIgniter's :doc:`URI Routing <../general/routing>` feature.
-
-	.. php:method:: segment_array()
-
-		:returns:	URI segments array
-		:rtype:	array
-
-		Returns an array containing the URI segments. For example::
-
-			$segs = $this->uri->segment_array();
-
-			foreach ($segs as $segment)
-			{
-				echo $segment;
-				echo '<br />';
-			}
-
-	.. php:method:: rsegment_array()
-
-		:returns:	Routed URI segments array
-		:rtype:	array
-
-		This method is identical to ``segment_array()``, except that it returns
-		the array of segments in your re-routed URI in the event you are using
-		CodeIgniter's :doc:`URI Routing <../general/routing>` feature.
