An unresponsive service can be worse than a down one. It can tie up your entire system if not handled properly. All network requests should have a timeout.

Here’s how to add timeouts for popular PHP packages. All have been tested. The default is no timeout, unless otherwise specified. Enjoy!

Also available for Ruby, Python, Node, Go, and Rust

Standard library

• cURL

Packages

• guzzlehttp/guzzle
• opensearch-project/opensearch-php
• predis/predis
• symfony/http-client

curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 1);

No exception is raised. Use curl_error($ch) to check for a timeout.

new GuzzleHttp\Client(['timeout'  => 1]);

Raises GuzzleHttp\Exception\ConnectException

$client = (new \OpenSearch\ClientBuilder())
    ->setConnectionParams(['client' => ['curl' => [CURLOPT_CONNECTTIMEOUT => 1, CURLOPT_TIMEOUT => 1]]])
    ->build();

Raises OpenSearch\Common\Exceptions\NoNodesAvailableException

new Predis\Client(['timeout' => 1, 'read_write_timeout' => 1]);

Default: 5s connect timeout

Raises Predis\Connection\ConnectionException

HttpClient::create(['timeout'  => 1]);

Raises Symfony\Component\HttpClient\Exception\TimeoutException
