求PHP远程更改图片名的代码

嘻嘻,我写的对上传图片进行改名的函数,写的比较乱你可以看看
function renameimage($file,$e) //$file为上传图片的名字，$e为上传图片所要放的文件夹的路径
{
$tupianname=explode(".",$file);//随机更改上传的图片名
$tupianname1=date("Ymdhis");
$tupianname1.=substr(md5(rand(0,100000)),0,4);
rename($tupianname[0],$tupianname1);
$tupianname1=$tupianname1.".".$tupianname[1];
$a=$e.$tupianname1;//最后生成的是路径加上文件名
return $a;
}

如何通过php连接远程主机并操作

一、最佳方案是在77机器上安装apache和php

二、可以通过管道控制使用telnet登录77号机执行命令并获取结果，ssh连接本人没有做过，telnet方法如下：

$f=fopen("telnet://192.168.0.77","rw");

$s=fgets($fp);
fputs($fp,"root");

$s=fgets($fp);
fputs($fp,"pass");

$s=fgets($fp);
fputs($fp,"df -h");

while(!feof($fp)){
$fp=fgets($fp);
echo $s;
}

fclose($fp);

手机输入真累~~~
