最近有个思路。想要监控本地文件变化 并上传到指定服务器。
刚开始有这个想法的时候找了很多资料。关于 windows 和linux 上怎么监控文件变化的
最后选择了 比较MD5值的方法。
我也写了一段 但是也大同小异。 于是 其中借用了别人的代码
他的github 是 https://github.com/tansuo1989/mydemo/blob/master/php-demo/file_watch.php
话不多说 上代码
<?php /** * Created by PhpStorm. * User: eddie * Date: 2018/3/5 * Time: 10:37 */ class FileWatch { protected $all = array(); public function __construct($dir) { $this->watch($dir); } //子类中重写这个方法 public function run($file) { } protected function all_file($dir) { if (is_file($dir)) { $this->all[$dir] = md5_file($dir); return $this->all; } if (is_dir($dir)) { $open = opendir($dir); while (($file = readdir($open)) !== false) { if ($file != "." && $file != "..") { $f = $dir . "/" . $file; if (is_file($f)) { $this->all[$f] = md5_file($f); } elseif (is_dir($f)) { $this->all_file($f); } } } } return $this->all; } public function watch($dir) { $this->all = array(); $old = $this->all_file($dir); while (true) { sleep(2); $this->all = array(); $new = $this->all_file($dir); $re = array_diff($new, $old); $del = array_diff_key($old, $new); $re = array_merge($re, $del); if ($re) { $this->all = array(); $old = $this->all_file($dir); $file = array_keys($re); $this->run($file[0]); } } } }//endclass //使用方法 class mywatch extends FileWatch { public function run($file) { if(!empty($file)) { echo "new file or file has been changed with ".$file.PHP_EOL; echo "please choose 1 or 0 to upload files or skip ".PHP_EOL; $fileName = explode('/', $file); while (true) { $a = trim(fgets(STDIN)); if(ctype_digit($a)) { echo $a.PHP_EOL; if($a == 1) { //上传文件 echo "you choose upload files ".PHP_EOL; // 判断系统 switch (PHP_OS) { //linux 需要用scp 命令 case 'Linux': exec('scp '.$file.' root@192.168.1.21:/home/'.$file); break; case 'WINNT': exec('PSCP.exe '.$file.' root@192.168.1.21:/home/'.end($fileName)); break; } break; } else { //不管 跳过 echo "you choose skip ".PHP_EOL; break; } } else { echo 'please enter 0 or 1'.PHP_EOL; } } } else { echo "no files has created and no files has been changed".PHP_EOL; } } } echo 'Your System is '.PHP_OS.PHP_EOL; echo "Welcome to use fileWatch System".PHP_EOL; $watch = new mywatch("./");
这段代码 在linux 上运行是没有报错 但是在windows 上运行 出错了 还在找原因。
