CI_URI::uri_to_assoc()

uri_to_assoc([$n = 3[, $default = array()]])

This method lets you turn URI segments into an associative array of key/value pairs. Consider this URI:

Using this method you can turn the URI into an associative array with this prototype:

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:

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:

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.
