How Can I Gracefully Set Curl Timeouts in PHP to Avoid Premature Termination of eXist Database Requests?

Setting Curl's Timeout Gracefully in PHP

In an attempt to overcome extended XML response times from an eXist database, a PHP curl request was implemented with a seemingly long timeout value. However, the request prematurely terminated before its completion.

As outlined in the PHP documentation, curl offers two distinct timeout settings:

• CURLOPT_CONNECTTIMEOUT: Specifies the timeout for establishing a connection (with a default of 30 seconds). Setting this to 0 indicates an indefinite wait.
• CURLOPT_TIMEOUT: Sets the maximum duration for all curl operations (with a default of 0, meaning no timeout). This timeout includes the time taken for both connection establishment and response retrieval.

For the given scenario, the following code modifications are recommended:

curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 0); // Wait indefinitely for connection establishment
curl_setopt($ch, CURLOPT_TIMEOUT, 400); // Set the timeout to 400 seconds

Additionally, it's essential to extend the PHP script's execution time to prevent premature termination. This can be achieved using set_time_limit(0) to allow for infinite execution time.

set_time_limit(0); // Allow for infinite execution time

By implementing these adjustments, curl's timeout behavior will be correctly configured, ensuring that the request has ample time to complete while preventing premature termination.
