[Script is sending multiple sms in application]

When the script executes, it sends the sms multiple times.  I don't know which variable to change for it to search the database once and then send out the message. This script was built for me and I modified it to change some variables.
 
        
 
I am very new to php
 
This is the first script, second is below
 
<?php

function responseMessage($message) {
   $xml = new SimpleXMLElement('<Response/>');
   if(is_array($message)) {
      
      $pageNow = isset($_GET["page"]) ? $_GET["page"] : 0;
      $limit = 1000;
      $doneRedirect = false;
      
      if(count($message) > 5) {
            $limit = ($pageNow * 5) + 5;
      }
      
      $i = 0;
      foreach($message as $msg) {
         if($msg != "" && $msg != null && strlen($msg) > 10 && !is_array($msg)) {
            $i++;
            if($i < $limit && $i >= ($pageNow * 5)) {
                $xml->addChild('Message', str_replace('&', "and", $msg));
            }
            else if(!$doneRedirect && $i >= ($pageNow * 5)) {
                $doneRedirect = true;
                $xml->addChild('Redirect', "/TwilioSMS.php?page=" . ($pageNow + 1));
            }
         }
      }
   }
   else {
      $xml->addChild('Message', $message);
   }

/*   $dom = new DOMDocument();
   $dom->loadXML($xml->asXML());
   $dom->formatOutput = true;
   $formattedXML = $dom->saveXML();*/
   
   return $xml->asXML();
}

function splitMessages($message) {
   $ar = explode("-/-/newline/-/-", wordwrap($message, 155, "-/-/newline/-/-", false));
//   array_pop($ar);
   return $ar;
}

function startsWith($haystack, $needle) {
   return $needle === "" || strrpos($haystack, $needle, -strlen($haystack)) !== false;
}

function checkKeyword($str, $arr) {
   foreach($arr as $srch) {
      if(startsWith($str, $srch)) {
         return $srch;
      }
   }
   return null;
}

$from = $_POST["From"];
$to = $_POST["To"];

   die("Unable to connect to SQL: " . mysqli_error($con));
}

/*if($from == "" || $to == "" || $body == "") {
   die("Invalid params");
}*/

$top = checkKeyword($body, array("top", "top 10", "top10"));

}

echo responseMessage($output);
 
This is the rider script - the only thing i'm using right now
 
<?php

$extra = "";

$search = mysqli_real_escape_string($con, substr($body, strlen($draw)));

$output = array();

$query = mysqli_query($con, "SELECT * FROM (SELECT *, MATCH(rider) AGAINST('*$search*' IN BOOLEAN MODE) AS score FROM `draws`) AS T WHERE score > 0 ORDER BY score DESC LIMIT 10");
while($row = mysqli_fetch_assoc($query))
{
    $info .= "" . $row["rider"] . " ";
    $info .= "" . $row["horse"] . "\n";
    $info .= "" . $row["run_time"] . "\n";
 
    
    
    
    $output[] = $info;
