php 模拟用户POST GET源代码

下面的代码使用两种方式来调facebook的接口，第一种县判断用户的环境是否开启了curl库，开启了这个库，就采用这种方式来获取请求。里面详细的参数讲解大家可以参考手册。

if(function_exists('curl_init'))
{
　　$ch = curl_init();
　　curl_setopt($ch, curlopt_url, $url_with_get);
　　curl_setopt($ch, curlopt_post, 1);
　　curl_setopt($ch, curlopt_postfields, $post);
　　curl_setopt($ch, curlopt_returntransfer, true);
　　$result = curl_exec($ch);
　　curl_close($ch);
}
else
{
　　$content = http_build_query($post)
　　$content_length = strlen($content);
　　$context =
　　array('http' =>
array('method' => 'post',
'user_agent' => $user_agent,
'header' => 'content-type: ' . $content_type . " " .
'content-length: ' . $content_length,
'content' => $content));
$context_id = stream_context_create($context);
$sock = fopen($url_with_get, 'r', false, $context_id);
$result = '';
if ($sock)
　　{
　　　　while (!feof($sock))
　　$result .= fgets($sock, 4096);
　　fclose($sock);
}
return $result;
}
}

测试代码

代码如下	复制代码
$url_with_get= "http://api.facebook.com/restserver.php?method=facebook.friends.get&session_key=&api_key=1232121311&v=1.0"; $post = array('sig'=>12312123234353);

这种一款可以统计你网站当前在线人数的代码哦，由php+txt实现的无需数据来来支持。

  $time = gettimeofday(void);

  //文件初始化 start
  if(@filesize("time.text")<=0){

   $fd_time = fopen("time.text","w+");
   fputs($fd_time,$time[sec]);
   fclose($fd_time);

   $fd_time = fopen("ip.text","w+");
   fclose($fd_time);

  }
  //文件初始化 over

  //更新时间 start
  $tamp = file("time.text");
  $equal = ($time[sec] - $tamp[0]);
  if($equal > 60){

   $fd_time = fopen("time.text","w+");
   fputs($fd_time,"");
    fclose($fd_time);

  }
  //更新时间 over

  //检查ip start
  $fd_ip = fopen("ip.text","a+");

 //获取用户ip地址
  if ($http_server_vars["http_x_forwarded_for"])
 {
 $ip = $http_server_vars["http_x_forwarded_for"];
 }
 elseif ($http_server_vars["http_client_ip"])
 {
 $ip = $http_server_vars["http_client_ip"];
 }
 elseif ($http_server_vars["remote_addr"])
 {
 $ip = $http_server_vars["remote_addr"];
 }
 elseif (getenv("http_x_forwarded_for"))
 {
 $ip = getenv("http_x_forwarded_for");
 }
 elseif (getenv("http_client_ip"))
 {
 $ip = getenv("http_client_ip");
 }
 elseif (getenv("remote_addr"))
 {
 $ip = getenv("remote_addr");
 }
 else
 {
 $ip = "unknown";
 }

    $ip_adds = file("ip.text");
    for($i;$i<count($ip_adds);$i++){

        if($ip." "==$ip_adds[$i]){
         $ip_check = 1;
         break;
        }
    }

    if($ip_check!=1){
     fputs($fd_ip,$ip." ");
    }
    fclose($fd_ip);
  //检查ip over

  $ip_adds = count(file("ip.text"));

本文章提供的确款正则表达式来检测url地址，日期格式，ip地址，与邮箱地址是否合法的验证代码,希望本文章对各位同学会带来帮助。

代码如下

复制代码

class validation{  function check_email($value){ //check a email address   return (bool) preg_match('/^[a-z0-9._%+-]+@(?:[a-z0-9-]+.)+[a-z]{2,4}$/i', $value);  }    function check_ip($value){ //check a ip address   return (bool) preg_match("/^(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?).){4}$/", $value.".");  }    function check_date($date, $format="dd/mm/yy"){ //check a date   if(!preg_match("/([0-9]+)([./-])([0-9]+)(\2)([0-9]+)/", $date, $m)) return false;   $f = explode("/", $format);   $d[$f[0]] = $m[1];   $d[$f[1]] = $m[3];   $d[$f[2]] = $m[5];   return checkdate($d['mm'], $d['dd'], $d['yyyy'].$d['yy']);  }    function check_url($url){ //check a url   return (bool) preg_match("/^(?:(?:ht|f)tp(?:s?)://|~/|/)?(?:(?:w+.)+)w+(?::d+)?(?:(?:/[^/?#]+)+)?/?(?:?[^?]*)?(#.*)?$/i", $url);  } }

//调用方法

代码如下	复制代码
$validation = new validation(); //检测邮箱 var_dump($validation->check_email("abc@abc.abc.com"));//true var_dump($validation->check_email("abc.abc@abc.com"));//false

//ip检测

代码如下	复制代码
var_dump($validation->check_ip("127.0.0.1.0")); var_dump($validation->check_ip("256.0.0.1"));

//日期格式检测

代码如下	复制代码
//true var_dump($validation->check_date("2010/1/20", "yyyy/mm/dd")); var_dump($validation->check_date("1/20/10", "mm/dd/yy")); var_dump($validation->check_date("2010-20-1", "yyyy/dd/mm")); //false var_dump($validation->check_date("2010/2/29", "yyyy/mm/dd")); var_dump($validation->check_date("2010/1/20", "yyyy/dd/mm")); var_dump($validation->check_date("2010-20/1", "yyyy/dd/mm"));

/*
此类的使用方法非常简单吧，只要创建类就可以轻松的验证邮箱，日期，地址，ip是否为合法的的哦。
*/

 

php正则判断中文字符

php教程正则判断中文字符

$str = "中国";
echo $str;
echo "<hr>";

//if   (preg_match("/^[".chr(0xa1)."-".chr(0xff)."]+$/", $str)) {   //只能在gb2312情况下使用
if   (preg_match("/^[x7f-xff]+$/", $str)) { //兼容gb2312,utf-8
     echo "正确输入";
} else {
     echo "错误输入";
}
?>

双字节字符编码范围

1. gbk (gb2312/gb18030)
x00-xff gbk双字节编码范围
x20-x7f ascii
xa1-xff 中文 gb2312
x80-xff 中文 gbk

2. utf-8 (unicode)

u4e00-u9fa5 (中文)
x3130-x318f (韩文
xac00-xd7a3 (韩文)
u0800-u4e00 (日文)

这是一款可以按时间日期来生成html类，他可以生成文件，同时也支持删除文件，删除目录，具有生成静态所有功能哦。

 

代码如下

复制代码

class html {     var $dir; //dir for the htmls(www.111cn.net/)     var $rootdir; //root of html files(www.111cn.net/):html     var $name; //html文件存放路径     var $dirname; //指定的文件夹名称     var $url; //获取html文件信息的来源网页地址     var $time; //html文件信息填加时的时间     var $dirtype; //目录存放方式:year,month,,,,     var $nametype; //html文件命名方式:name             function html($nametype = 'name', $dirtype = 'year', $rootdir = 'html')     {         $this -> setvar($nametype, $dirtype, $rootdir);         }         function setvar($nametype = 'name', $dirtype = 'year', $rootdir = 'html')     {         $this -> rootdir = $rootdir;         $this -> dirtype = $dirtype;         $this -> nametype = $nametype;         }         function createdir($dir = '')     {         $this -> dir = $dir?$dir:$this -> dir;                 if (!is_dir($this -> dir))             {             $temp = explode('/', $this -> dir);             $cur_dir = '';             for($i = 0;$i < count($temp);$i++)             {                 $cur_dir .= $temp[$i] .
