PHP server PHP writes file multi-server synchronization program

The example in this article shares with you the PHP file multi-server synchronization tool. The specific content is as follows

<&#63;php
header('Content-type:text/html;charset=utf-8');
//文件名称：PHP文件多服务器同步工具
//文件作用：本文件所在服务器为主服务器，其它文件所在服务器可作分流或者备份。本文件需要jQuery库。你也可以外链别人的

if(!empty($_POST['files'])) sync();
 
function sync(){
  $aFiles   = explode("\n", $_POST['files']);
//var_dump($aFiles);exit;
  foreach($aFiles as $k => $v){
    if(strlen($v) <= 5) unset($aFiles[$k]);
  }
  array_filter($aFiles);
  if(empty($aFiles)) {
    echo '没有文件'; exit;
  }
  $aFTPServers = array(
            'server1' => array('strwei.com','FTP用户名','FTP密码', '打开FTP进去时的默认目录'),//ftp地址、用户名，密码、FTP打开此站点时的默认目录
            //'server2' => array('yy.9.je','FTP用户名','FTP密码','打开FTP进去时的默认目录'),
  );
  $aAbortFile = array('robots.txt');
  $aErrors   = array();
  $iError   = count($aErrors);
  $aSuc    = array();
  foreach($aFTPServers as $ftp) {
    $conn  = ftp_connect($ftp[0]);
    if(empty($conn)){
      $iError = $iError + 1;
      array_push($aErrors, $iError . "、服务器 $ftp 无法连接");
      continue;
    }
    $login = ftp_login($conn, $ftp[1], $ftp[2]);
    if(empty($login)){
      $iError = $iError + 1;
      array_push($aErrors, $iError . "、服务器 $ftp[0] 无法登录");
      continue;
    }
 
    $ftp_root = '';
    if(!empty($ftp[3])) $ftp_root = ftp_chdir($conn, $ftp[3]);

    foreach($aFiles as $k => $v){
      $s = basename($v);
      if(in_array($s, $aAbortFile)) {
        $iError = $iError + 1;
        array_push($aErrors, $iError . "、文件 $v 不允许同步");

        $iError = $iError + 1;
        array_push($aErrors, $iError . "、文件 $v 不存在");
        continue;
      }
      $upload = ftp_put($conn, $ftp_root . $v, '.' . $v, FTP_BINARY);
      if(empty($upload)){
        $iError = $iError + 1;
        array_push($aErrors, $iError . "、文件 $v 上传失败");
        continue;

请输入你要同步的文件名（包括它的路径），例如：inoutcome_final.zip、/default.php、/index.php、/inoutcome_final.sqlite等等，每行输入一个文件名，可回车输入多个<br><br>
<textarea  ></span>
 
<script>
function submit_sync(){
  $("#btn_submit").hide();
  var sFiles = $("#id_file").val();
  var aFiles = sFiles.split(/$cc/);
  if(aFiles.length <= 0 || aFiles[0].length <= 5) {
    alert("请手工写入要同步的文件清单");
    $("#btn_submit").show("slow");
    return false;
  }
  $.post("?", {"files":sFiles}, function(v){
    $("#show_sync").text(v);
    if(v.indexOf("上传成功") != -1) $("#id_file").val('');
    $("#btn_submit").show(5000);
  })
  return true;
}
</script>
 
EOF;
?>
