html - simulate a link call using php code

i create a link, in html page, that when it is clicked, it calls a URL to another site, that cause the other site to send a response to a different URL (doesnt matter which one).

i create the html link like this:

print "<a class='login' href='$authUrl'>Connect Me!</a>";
Copy code

then when i click the link, the other site sends the response ok.

now i need to do the above link call , but in php code, which i believe, means call a GET request using curl?

i tried it so many times but i can't seem to make it work like the link click above. This is my code:

$curl = curl_init();

curl_setopt_array($curl, array(

    CURLOPT_RETURNTRANSFER => 0,
    CURLOPT_URL => $authUrl,
Copy code

)) $result = curl_exec($curl);

$GLOBALS['log']->fatal("error = " . curl_error($curl));

curl_close($curl);

but it doesn't work and the other site doesn't respond.

i get 1 as a result.

did i call the link ok? is it exactly like clicking on the link in the first example?
