function language_list

Returns a list of installed languages, indexed by the specified key.

Parameters

$field: (optional) The field to index the list with.

Return value

An associative array, keyed on the values of $field.

• If $field is 'weight' or 'enabled', the array is nested, with the outer array's values each being associative arrays with language codes as keys and language objects as values.
• For all other values of $field, the array is only one level deep, and the array's values are language objects.
