How to use MySQL query to Twilio SMS phone based on results

Question

I'm using the Twilio API to send broadcast SMS messages based on an approved number. The problem in which I have encountered is not being able to successfully run a query pulling the phone information from a database and enter it into the API for each results that meet the query criteria to send an SMS to. The below is what I have so far.

    //Include the PHP TwilioRest library
    require "Services/Twilio.php";

    //Set our AccountSid and AuthToken
    $AccountSid = "ACXXXXXXXXXXXXXXXXXXXXXXXXX";

    $AuthToken = "YYYYYYYYYYYYYYYYYYYYYYYYYYYYY";

   //Instantiate a new Twilio Rest Client
    $client = new Services_Twilio($AccountSid, $AuthToken);

//Trusted numbers that we want to be able to send a broadcast

    $trusted = array("+33333333333" => "ApprovedAdmin1");

//An unauthorized user tried to send a broadcast.

    if(!$name = $trusted[$_REQUEST['From']])

    {header("content-type: text/xml");echo "\n";echo "Unauthorized broadcaster, contact an admin for access.";exit(0);}

//These are the recipients that are going to receive the broadcasts

//database user credentials  
    `$user = "user";`  
    `$password = "password";`  
    `$database = "database";` 
    `$host = "localhost";`  
//connect to the database  
    `$DB = mysql_connect($host, $user, $password) or die("Can't connect to database.");`  
    `@mysql_select_db($database) or die("Unable to select database");`

//Used to query database for only user phone numbers who accept texts

    $recipients = array (mysql_query("SELECT phone FROM sms WHERE (accept_text = 'Y')"));

//I have commented this out to try to get the query to work. The below recipients array does work and even lists the names of the user in the SMS.

    //$recipients = array("+22222222222" => "testuser1");

//Grab the message from the incoming SMS

    $msg = $_REQUEST['Body'];

// Iterate over all our recipients and send them the broadcast

    //foreach ($recipients as $number => $name) {

//Send a new outgoinging SMS by POSTing to the SMS resource

    $sms = $client->account->sms_messages->create("3333333333",$number,"$name, " . $msg);echo $name . " ";}

Ok so first of all you are not executing valid XML on the error condition e.g. if the user is not a trusted number. If you want to reply to the texter that the number is unauthorised you would need to do:

header("content-type:text/xml");
echo "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n";
echo "<Response>\n<Sms>Unauthorized broadcaster, contact an admin for access.</Sms>\n</Response";

I'm not sure what you are trying to do with the query - why is it in an array? And I don't know why you then have a recipients array - surely this is what you are pulling in from the database? You need to do:

$result = mysql_query("SELECT phone FROM sms WHERE accept_text = 'Y'");
while($row = mysql_fetch_assoc($result)) {
    $client->account->sms_message->create("3333333333", $row['phone'], $_REQUEST['Body']); 
}
