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。
