Question

Curl install in cent os but not working

Hello,

I have install CURL in cent OS.

I can see in my PHPINFO.

I also install LARAVEL.

But when i call curl return 0.

i have also setup firewall and allowed 80 and 443 port

 $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>";
                }

It’s “Return code is 0”;

I am able to solve this error by executing below command. Most of the time we face if SELinux is enabled on our server. The curl request is blocked by SELinux.

setsebool -P httpd_can_network_connect on

after that restart your server.

sudo systemctl restart httpd

I am also facing this issue, please let us know if there is any solution. Server - Getting this issue on Cetos server with php version 8.0. If anyone find the resolution for this than please be kind to share info.

Hi @sharmahemal811,

I tested your script and I can confirm I got a HttpCode 200.

Now, you were wondering why was executing

curl www.google.com

From the command line working but when you put it in a script it didn’t work. The curl you are using from the command line is actually very different than the one you are using in php scripts.

Basically, in your command line, you are using curl and in your php scripts, you are using an extension for php called php-curl. While the command-line curl comes installed by default, that is not the case for php-curl. As such all you need to do is install php-curl.

Depending on the php version installed (7, 7.2, 7.3, 7.4), you need to run the following command:

yum install php-curl

or

yum install php7.2-curl

Now, if you are using another php version just change the number 7.2 as you like.
