How can I get a list of Elasticsearch index names using the Elasticsearch-PHP client?
I figured it out through trial and error.
The way to get a list of indices matching a pattern is:
$client = ClientBuilder::create()->build();$indices = $client->cat()->indices(array('index' => '*.foo.bar'));
In the current docs at the time of this response (7.2), you can find the documentation for the endpoint GET /_cat/indices/ that you're looking for.
So you can get the indices with this code:
$params = [ // Example of another param 'v' => true, // ... 'index' => '*.foo.bar'];$indices = $client->cat()->indices($params);The documentation doesn't explicitly states about the index param, but you can see how the index is set inside the CatNamespace::indices() method definition.
public function indices(array $params = []){ $index = $this->extractArgument($params, 'index'); ... $endpoint->setIndex($index); ...}
