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
/**

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 ‘.$file.‘ [email protected]:/home/‘.$file);
break;
case ‘WINNT‘:
exec(‘PSCP.exe ‘.$file.‘ [email protected]:/home/‘.end($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。
