If you re using selinux it might be because of security restrictions   Try setting this as root    setsebool -P httpd can network connect on

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    lt  php   html brand    www google com    ch   curl init      options   array      CURLOPT URL              gt   html brand      CURLOPT RETURNTRANSFER   gt  true      CURLOPT HEADER           gt  true      CURLOPT FOLLOWLOCATION   gt  true      CURLOPT ENCODING         gt          CURLOPT AUTOREFERER      gt  true      CURLOPT CONNECTTIMEOUT   gt  120      CURLOPT TIMEOUT          gt  120      CURLOPT MAXREDIRS        gt  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   lt pre gt   htmlspecialchars  response    lt  pre gt       curl close  ch

I had same problem and in my case this was because curl exec function is disabled in php ini  Check for logs   PHP Warning   curl exec   has been disabled for security reasons in  var www     html test php on line 18   Solution is remove curl exec from disabled functions in php ini on server configuration file

Try this after curl exec to see what s the problem    print curl error  ch     If it s print something like  malformed  then check your URL format

Another reason for PHP to return http code 0 is timeout  In my case  I had the following configuration   curl setopt  http  CURLOPT TIMEOUT MS 500    It turned out that the request to the endpoint I was pointing to always took more than 500 ms  always timing out and always returning http code 0   If you remove this setting  CURLOPT TIMEOUT MS  or put a higher value  in my case 5000   you ll get the actual http code  in my case a 200  as expected    See https   www php net manual en function curl-setopt php

check the curl error after the curl getinfo to find out the hidden errors    if curl errno  ch           echo  Curl error      curl error  ch

Like said here and below  a failed request  i e  the server is not found  returns false  no HTTP status code  since a reply has never been received   Call curl error
