PHP Curl Http Code Return 0

PHP cURL HTTP CODE return 0

If you connect with the server, then you can get a return code from it, otherwise it will fail and you get a 0. So if you try to connect to "www.google.com/lksdfk" you will get a return code of 400, if you go directly to google.com, you will get 302 (and then 200 if you forward to the next page... well I do because it forwards to google.com.br, so you might not get that), and if you go to "googlecom" you will get a 0 (host no found), so with the last one, there is nobody to send a code back.

Tested using the code below.

<?php

$html_brand = "www.google.com";
$ch = curl_init();

$options = array(
    CURLOPT_URL            => $html_brand,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_HEADER         => true,
    CURLOPT_FOLLOWLOCATION => true,
    CURLOPT_ENCODING       => "",
    CURLOPT_AUTOREFERER    => true,
    CURLOPT_CONNECTTIMEOUT => 120,
    CURLOPT_TIMEOUT        => 120,
    CURLOPT_MAXREDIRS      => 10,
);
curl_setopt_array( $ch, $options );
$response = curl_exec($ch); 
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);

if ( $httpCode != 200 ){
    echo "Return code is {$httpCode} \n"
        .curl_error($ch);
} else {
    echo "<pre>".htmlspecialchars($response)."</pre>";
}

curl_close($ch);

Anything wrong with my cURL code (http status of 0)?

Realized that I was having SSL issues. Simply set CURLOPT_SSL_VERIFYPEER and CURLOPT_SSL_VERIFYHOST to false. Works.

PHP cURL Problems: HTTP Code 0

You need to call curl_exec($ch); before curl_getinfo($ch); cause this is the actual connection to the server:

also there is no need in the flag CURLOPT_POST since it's a get call:

// create a new cURL resource
$ch = curl_init();

//for post calls:
//$post = 'a=b&d=c';
//$headers[] = 'Content-type: application/x-www-form-urlencoded;charset=utf-8';
//$headers[] = 'Content-Length: ' . strlen($post);

//for get calls:
$headers = array();
$headers[] = 'Content-type: charset=utf-8'; 

$headers[] = 'Connection: Keep-Alive';

// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.yahoo.com");
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
//curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);

curl_exec($ch);
$report=curl_getinfo($ch);
print_r($report);

// grab URL and pass it to the browser

if(curl_errno($ch)) {
   echo 'Curl error: ' . curl_error($ch);
}

print curl_error($ch);

// close cURL resource, and free up system resources
curl_close($ch);

Why my code returns an http 0 response instead of expected 200?

I finally found what was the problem: my hosting server firewall has some ports closed, that do not allow a response for some URLs.
