* 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()
|

* )
