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.

Takes an associative array as input and generates a URI string from it.
The array keys will be included in the string. Example::
