Add support for CURLINFO_QUEUE_TIME_T in curl_getinfo()

Summary

This patch adds support for the CURLINFO_QUEUE_TIME_T constant in the curl_getinfo() function when compiled with libcurl >= 8.6.0.

CURLINFO_QUEUE_TIME_T This constant allows retrieving the time (in microseconds) that the request spent in libcurl’s connection queue before it was sent.

Details

• Introduced support for curl_getinfo($ch, CURLINFO_QUEUE_TIME_T) when available.
• Added "queue_time_us" key to the associative array returned by curl_getinfo($ch) if applicable.
• A SKIPIF check ensures that the test is skipped if the libcurl version is too old.
• Includes a .phpt test file: ext/curl/tests/curl_getinfo_CURLINFO_QUEUE_TIME_T.phpt.

Requirements

• Requires libcurl version 8.6.0 or higher.
• PHP runtime will fallback silently if the constant is not available in the underlying libcurl.

Example usage

$ch = curl_init("https://example.com");
curl_exec($ch);
$queueTime = curl_getinfo($ch, CURLINFO_QUEUE_TIME_T);
echo "Queue Time: $queueTime\n";
