I look at a site php, to tell me a bit about the "function" and the "return" so I created two page, test and b.php

in test.php

PHP код:

<?php
include("b.php");
  for ($i=0;$i<$count;$i++) 
  {
    echo "player: ".$data[$i]['player'].", <strong>score</strong> ".$data[$i]['score']."<br>";
  }
  $data = GetPlayers("51.254.29.46", "30465");
  $count = count($data);
  for ($i=0;$i<$count;$i++) {
    echo "player: ".$data[$i]['player'].", <strong>score</strong> ".$data[$i]['score']."<br>";
  }
?>

and in b.php

PHP код:

<?php
function GetPlayers($server_ip, $server_port) {
  $fp = fsockopen('udp://'.$server_ip, $server_port, $errno, $errstr);
  stream_set_timeout($fp, 5);
  if (!$fp) return false;
  
  $packet = 'SAMP';
  $packet .= chr(strtok($ip, '.'));
  $packet .= chr(strtok('.'));
  $packet .= chr(strtok('.'));
  $packet .= chr(strtok('.'));
  $packet .= chr($port & 0xFF);
  $packet .= chr($port >> 8 & 0xFF);
  
  fwrite($fp, $packet.'c');
  fread($fp, 11);
  $players = ord(fread($fp, 2));
  
  $start = 0;
  if ($players > 0)    {
      for ($i=0;$i<$players;$i++)    {
          $strlen = ord(fread($fp, 1));
          $player = fread($fp, $strlen);
          $score = ord(fread($fp, 4));
          $data[$start]['player'] = $player;
          $data[$start]['score'] = $score;
          $start++;
      }
  }
  fclose($fp);
  return 1;
}  
?>

the problem is always the same, when I put return 1;
he shows me in the page


and when I put return $data;
he shows me in the page
