使用php客户端库从elasticsearch中的别名获取索引名称

Question

I am creating index with alias and I want to get index name from alias in elasticsearch using php client library. Below is my code to add alias in index.

$params['body'] = array(
        'actions' => array(
            array(
                'add' => array(
                    'index' => 'solatiers_with_alias',
                    'alias' => 'solatiers_alias'
                    )
                )
            )
        );
$client->indices()->updateAliases($params);

How can I retrieve index name from alias?

Answer 1

You can get retrieve index name by

function myfunction($value,$key)
{
 if($key="index"){
    echo $value;
    break;
    }
}
array_walk_recursive($params['body'],"myfunction");
