PHP Question

Why does a ’www.’ URL-prefix affect whether cURL can grab webpage content?

Here's my setup:

$url1 = "";
$url2 = "";

$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 20);
$result = curl_exec($curl);

will result in an empty string and
will work as intended. But why my fellow stackoverflowians, is cURL so delicate when it comes to the presence of ‘www.’ , when it (in my experience) doesn’t matter when using URLs in my browser (firefox).

Thanks in advance!

Your browser follows the redirect transparently.

PHP/cURL, with your settings, does not. This question explains how to change that.
