cookie 的用途之一是存储用户在特定网站上的密码和 id。另外，也用于存储起始页的首选项。在提供个人化查看的网站上，将要求阁下的网络浏览器利用阁下计算机硬驱上的少量空间来储存这些首选项。这样，每次阁下登录该网站时，阁下的浏览器将检查阁下是否就该唯一的服务器有任何预先定义的首选项（cookie）。如果有的话，浏览器将此 cookie 随阁下对网页的请求一起发送给服务器。microsoft 和 netscape 使用 cookie 在其网站上创建个人起始页。各家公司利用 cookie 的一般用途包括：在线定货系统、网站个人化和网站跟踪

set-cookie: name = value;
expires = date;
path = path;
domain = domain_name;

下面来看看关于cookie的简单用户登录实例

login.php教程这个是处理登录

 代码如下:
<?php
if($_post['username'] = 'admin')
{
setcookie('haha','gogo');
header("location:index.php");
}
?>

index.php再看下效果
 代码如下:

<?php
if($_cookie['haha'] == 'gogogo')
{
echo $_cookie['haha'];
echo'你设置了cookie';
}
else
{
echo'你没有设置cookie';
}
?>

 login_frm.php这个是登录窗口
代码如下:

<html>
<head>
<meta http-equiv="content-type" content="text/html;charset=utf8" />
</head>
<body>
<form method="post" action="login.php">
用户:<input type="text" name="username" />
<input type="submit" value="提交" />
</form>
</body>
</html> 

ob_start（[string output_callback]）- 打开输出缓冲区
　　所有的输出信息不在直接发送到浏览器，而是保存在输出缓冲区里面,可选得回调函数用于处理输出结果信息。
ob_end_flush - 结束（发送）输出缓冲区的内容，关闭输出缓冲区

*/

ob_start();          //打开缓冲区
echo "hello world";        //输出内容
$out=ob_get_clean();       //获得缓冲区内容并且结束缓冲区
$out=strtolower($out);       //将字符转换为小写
var_dump($out);        //输出结果

//

if(!function_exists('ob_clean'))      //判断函数是否被定义
{
  function ob_clean()       //定义函数
  {
    if(@ob_end_clean())
    {
      return ob_start();
    }
    trigger_error("ob_clean() failed to delete buffer.no buffer to delete.",e_user_notice);
    return false;
  }
}

//

header('content-type: multipart/x-mixed-replace;boundary=endofsection');  //发送标头
print "n--endofsectionn";           //输出内容

for($i=0;$i<10;$i++)            //通过循环进行操作
{

  print "content-type: text/plainnn";         //输出内容
  print "part $it".$pmt[$i % 4];          //输出内容

<?php教程     $test = "ls /tmp/test";     $out = shell_exec($test);     echo $out;     ?> 　　

popen,passthru,proc_open,shell_exec的返回结果如下：

[root@krlcgcms01 shell]# php test.php     1001.log     10.log     10.tar.gz     aaa.tar.gz     mytest     test1101     test1102     weblog_2010_09   　　我能发现的就这几个函数，能执行linux下的命令，我想应当还有吧，欢迎大家补充。

　　一般情况下，很少会用php去执行linux命令，不过特殊情况下，你也许会用到这些函数。以前我知道有二个函数可以执行linux命令，一个是exec,一个是shell_exec。其实有很多的，结合手册内容，介绍以下6个函数。

　　1，exec函数

<?php     $test = "ls /tmp/test";   //ls是linux下的查目录，文件的命令     exec($test,$array);       //执行命令     print_r($array);     ?>  

　　返回结果如下：

[root@krlcgcms01 shell]# php ./exec.php     array     (      [0] => 1001.log      [1] => 10.log      [2] => 10.tar.gz      [3] => aaa.tar.gz      [4] => mytest      [5] => test1101      [6] => test1102      [7] => weblog_2010_09     )
