<br />
<?PHP<br />
class rar<br />
{<br />
<br />
public $Path; //文件路径<br />
<br />
public $Save; //保存路径<br />
<br />
public $Object; //Wscript.Shell对象实例<br />
<br />
function rar(){ //构造函数<br />
<br />
$this->Object = new com("Wscript.Shell"); //实例化一个Shell对象<br />
<br />
}<br />
<br />
function Release(){ //解压方法<br />
<br />
$this->Object->run("WinRAR x $this->Path $this->Save",1,false); //Path要解压的文件名及路径 Save保存路径<br />
<br />
   if($this->Object == true){<br />
<br />
   return true;<br />
<br />
   }else{<br />
<br />
   return false;<br />
<br />
   }<br />
<br />
}<br />
<br />
function Pressure(){ //压缩方法<br />
<br />
$this->Object->run("WinRAR a $this->Save $this->Path",1,true); //Save压缩后保存的路径及文件名 Path要压缩的路径<br />
<br />
   if($this->Object == true){<br />
<br />
   return true;<br />
<br />
   }else{<br />
<br />
   return false;<br />
<br />
   }<br />
<br />
}<br />
}<br />
<br />
<br />
$rar=new rar();<br />
$rar->Path="F:/js/test/z.rar";<br />
$rar->Save="F:/js/test";<br />
if($rar->Release()){<br />
die('解压成功');<br />
