* Get the stucture of a field into an array
*
* @param string $table name of the table on which the index is to be created
* @param string $name name of the index to be created
* @param array $definition associative array that defines properties of the index to be created.
* Currently, only one property named FIELDS is supported. This property
* is also an associative with the names of the index fields as array
* indexes. Each entry of this array is set to another type of associative
* array that specifies properties of the index that are specific to
* each field.
*
* Currently, only the sorting property is supported. It should be used
* to define the sorting direction of the index. It may be set to either
* ascending or descending.
*
* Not all DBMS support index sorting direction configuration. The DBMS
* drivers of those that do not support it ignore this property. Use the
* function support() to determine whether the DBMS driver can manage indexes.
* Example
* array(
* 'fields' => array(
* 'user_name' => array(
* 'sorting' => 'ascending'
* ),
* 'last_login' => array()
* )
* )
* @throws PDOException
