 Using this function you can turn the URI into an associative array with
 this prototype::
 
-	[array] (     'name' => 'joe'     'location'  => 'UK'     'gender'    => 'male' )
+	[array]
+	(
+	    'name' => 'joe'
+	    'location'	=> 'UK'
+	    'gender'	=> 'male'
+	)
 
 The first parameter of the function lets you set an offset. By default
 it is set to 3 since your URI will normally contain a
 controller/function in the first and second segments. Example::
 
-	 $array = $this->uri->uri_to_assoc(3);  echo $array['name'];
+	$array = $this->uri->uri_to_assoc(3);
+
+	echo $array['name'];
 
 The second parameter lets you set default key names, so that the array
 returned by the function 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);
+	$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 FALSE.
