Php Curl is not working curl_getinfo returns array where all variables are zero

Question

I have this test code:

<?php

$html_brand = "https://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($ch);
    print_r(curl_getinfo($ch));
} else {
    echo "<pre>".htmlspecialchars($response)."</pre>";
}

curl_close($ch);

And page result (I have put \n before variable name for better readability) is:

Return code is 0 Array ( 
[url] => https://google.com 
[content_type] => 
[http_code] => 0 
[header_size] => 0 
[request_size] => 0 
[filetime] => 0 
[ssl_verify_result] => 0 
[redirect_count] => 0 
[total_time] => 0 
[namelookup_time] => 0 
[connect_time] => 0 
[pretransfer_time] => 0 
[size_upload] => 0 
[size_download] => 0 
[speed_download] => 0 
[speed_upload] => 0 
[download_content_length] => -1 
[upload_content_length] => -1 
[starttransfer_time] => 0 
[redirect_time] => 0 
[redirect_url] => 
[primary_ip] => 
[certinfo] => Array ( ) 
[primary_port] => 0 
[local_ip] => 
[local_port] => 0 )

What is wrong here? I could not figure out why curl is not working on my machine. Internet is working, command line curl is working very fine. I'm on PHP Version 5.5.9-1ubuntu4.14, and this is curl section from phpinfo()

Have you tried dumping curl error var_dump(curl_error($ch));? — Charlotte Dunois

but that answer doesn't help me, because I don't know what is wrong. curl doesn't return anything useful to determine what's wrong — Gondy

There's likely nothing wrong with your code (I tried it, straight copy paste worked) you're likely getting blocked by a firewall or something. A status code of 0 usually means the server was never reached. You could try ping google.com from your server's console. Check out this question stackoverflow.com/questions/10227879/… — Squeegy

I have found out that I have disabled curl_exec function in php.ini. In apache2 log:

PHP Warning:  curl_exec() has been disabled for security reasons in /var/www/***/html/test.php on line 18

Enabling it in php.ini did the trick!
