本文实例讲述了PHP模拟asp中response类的方法。分享给大家供大家参考。具体如下:

习惯了asp或是asp.net开发的人, 他们会经常用到response类,这个类用于处理客户端的响应,可以实现跳转,输出等功能. 在php中没有这个类,但是确实可以通过函数来模拟这个类.

/* * 类用途: 实现类似于asp中的response功能 */final class Response {   private $headers = array();    private $output;   private $level = 0;   public function addHeader($key, $value) {     $this->headers[$key] = $value;   }   public function removeHeader($key) {     if (isset($this->headers[$key])) {       unset($this->headers[$key]);     }   }   public function redirect($url) {     header("Location: " . $url);     exit;   }   public function setOutput($output, $level = 0) {     $this->output = $output;     $this->level = $level;   }   private function compress($data, $level = 0) {     if (isset($_SERVER["HTTP_ACCEPT_ENCODING"]) && (strpos($_SERVER["HTTP_ACCEPT_ENCODING"], "gzip") !== FALSE)) {       $encoding = "gzip";     }      if (isset($_SERVER["HTTP_ACCEPT_ENCODING"]) && (strpos($_SERVER["HTTP_ACCEPT_ENCODING"], "x-gzip") !== FALSE)) {       $encoding = "x-gzip";     }     if (!isset($encoding)) {       return $data;     }     if (!extension_loaded("zlib") || ini_get("zlib.output_compression")) {       return $data;     }     if (headers_sent()) {       return $data;     }     if (connection_status()) {        return $data;     }     $this->addHeader("Content-Encoding", $encoding);     return gzencode($data, (int)$level);   }   public function output() {     if ($this->level) {       $ouput = $this->compress($this->output, $this->level);     } else {       $ouput = $this->output;     }       if (!headers_sent()) {       foreach ($this->headers as $key => $value) {         header($key . ": " . $value);       }     }     echo $ouput;   } }

希望本文所述对大家的php程序设计有所帮助。
