示例1: lists
/**
* Get an array with the values of a given column.
*
* @param string $column
* @param string $key
* @return array
*/
public function lists($column, $key = null)
{
$columns = $this->getListSelect($column, $key);
// First we will just get all of the column values for the record result set
// then we can associate those values with the column if it was specified
// otherwise we can just give these values back without a specific key.
$res = $this->get($columns);
$results = new Collection($res->getData());
$values = $results->fetch($columns[0])->all();
// If a key was specified and we have results, we will go ahead and combine
// the values with the keys of all of the records so that the values can
// be accessed by the key of the rows instead of simply being numeric.
if (!is_null($key) && count($results) > 0) {
$keys = $results->fetch($key)->all();
return array_combine($keys, $values);
}
return $values;
}示例2: scopeListsNested
/**
* Gets an array with values of a given column. Values are indented according to their depth.
* @param string $column Array values
* @param string $key Array keys
* @param string $indent Character to indent depth
* @return array
*/
