如何在PHP中获取IP地址的内容

Question

Im trying to use PHP file_get_contents for an IP. Example:

echo file_get_contents("1.22.22:2334/pay");

However PHP And Curl does not return the contents of the IP address, How would i go about doing this?

Thank you very much.

You should use curl as file_get_contents requires allow_url_fopen to be on in the php.ini config file (which is not always the case).

With curl and IP only it should be like:

    // create curl resource 
    $ch = curl_init(); 

    // headers for ip only
    $headers = array("Host: www.myfaketopsite.com");
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_URL, "https://1.22.22:2334/pay");

    //return the transfer as a string 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 

    // $output contains the output string 
    $output = curl_exec($ch); 

    // close curl resource to free up system resources 
    curl_close($ch);      

Answer partly from: PHP cURL connect using IP address instead domain name
