Question

I get the warning message: file_get_contents failed to open stream permission denied

I have set all_url_open to on in the php.ini file.

My php file is in my apache server and it is trying to access a url (that returns JSON) from a tomcat server on the same machine.

The code in the php file looks like:

  $srcURL = 'http://samemachine:8080/returnjson/';

  $results = file_get_contents($srcURL);

I have also tried curl and it returns nothing and doesn’t hit the tomcat server either:

    function curl($url){
        $ch = curl_init();

        curl_setopt($ch, CURLOPT_HTTPHEADER, array('Accept-Language: en-us'));
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
        $data = curl_exec($ch);

        curl_close($ch);
        return $data;
    }

Why is permission denied?

Answer 1

• Make sure it’s really allow_url_fopen and not all_url_open as you wrote
• Double-check this by running phpinfo(). Make sure it lists the option as enabled. If it doesn’t restart your web server
• To debug your curl problem, run Wireshark and watch on the lo interface
