如何将我的脚本从仅使用美国电话号码更改为使用美国和国际或至少英国号码

Question

I have a script that gathers a phone numbers and sends it out through a URL into another script. The script works fine for US numbers but I cannot get it to work with UK numbers and I have tried to figure it out with no luck. Any help would be appreciated.

This is the code I am using.

<?php
session_start();

  function post_to_sms($url,$post_string)
  {
    // post form to SMS API

    $curl_result=$curl_err='';
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL,$url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post_string);

    // note - set HOST where your API resides
    curl_setopt($ch, CURLOPT_HTTPHEADER, array("POST /cgi-bin/webscr HTTP/1.1",
            "Content-Type: application/x-www-form-urlencoded", 
            "Content-Length: " . strlen($post_string),
            "Host: yourdomain.com",
            "Connection: close"));

    curl_setopt($ch, CURLOPT_HEADER , 0);   
    curl_setopt($ch, CURLINFO_HEADER_OUT , 1);   
    curl_setopt($ch, CURLOPT_VERBOSE, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($ch, CURLOPT_TIMEOUT, 30);

    $curl_result = @curl_exec($ch);

    // 2 lines of debug (comment for production)
//   print_r(curl_getinfo($ch));
//    echo "<br /> error = " . $curl_err = curl_error($ch);

    curl_close($ch);

    return $curl_result;
  } // end of CURL function

  // URL for your SMS API
  $url = "yourdomain.com/sms/sms_controlling.php";

  if( isset($_REQUEST['telNumber']) )
  {
    if( is_numeric( $_REQUEST['telNumber'] ) && ( $_REQUEST['telNumber'] > '1000000000' ) &&  ( $_REQUEST['telNumber'] < '9999999999' ) )
    {

        // create array of form variables
        // 'From' is input - 'To' and 'Body' is hard-coded 

        $post_data['From'] = $_REQUEST['telNumber'];
        $post_data['To'] = "%2b17204447777";  //Enter Twilio Phone number
        $post_data['Body'] = "keyword Here";  //Enter The Keyword to your SMS Campaign.

        foreach ( $post_data as $key => $value) 
        {
          $post_items[] = $key . '=' . $value;
        }
        $post_string = implode ('&', $post_items);

        post_to_sms( $url, $post_string );

    } else {
      $_SESSION['errmessage'] = "Sorry.  All 10 Digits of Phone Number (incl Area Code) are required.";
    }
  }

  ?>

As philnash has pointed out, UK numbers start 44. Depending on the interface you are using you might need to simply set the number prefix to 44, +44 or you might need to set the Number Plan Indicator. The + commonly preceding international numbers is a shortcut for mobile devices to set the NPI and does not normally have any relevance in messaging protocols otherwise... so you will need to consult with your SMS provider.
