For anyone who’s ever tried to fetch multiple resources over HTTP in PHP, the logic is trivial, but one key challenge is ever-present: latency delays. While web servers have perfectly good downstream links, latencies can increase script execution time tenfold just by downloading a few external URLs. But there’s a simple solution: parallel cURL operations. In this tutorial, I’ll show you how to use the “multi” functions in PHP’s cURL library to get around this quickly and easily.
