php-guzzleHow to convert a Guzzle request to a cURL request in PHP?

Converting a Guzzle request to a cURL request in PHP is relatively straightforward. The following example code block shows how to do this:

$client = new GuzzleHttp\Client();
$res = $client->request('GET', 'http://www.example.com');

$curl = curl_init();
curl_setopt_array($curl, array(
    CURLOPT_URL => "http://www.example.com",
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_ENCODING => "",
    CURLOPT_MAXREDIRS => 10,
    CURLOPT_TIMEOUT => 30,
    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
    CURLOPT_CUSTOMREQUEST => "GET",
    CURLOPT_HTTPHEADER => array(
        "cache-control: no-cache"
    ),
));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
    echo "cURL Error #:" . $err;
} else {
    echo $response;
}
