摘录个好用的php下载方法,放哪哪用。
HttpUtil类摘录于thinkphp3.2。
因为thinkphp5.0无该方法,所以挪来用了。
觉得真心好用就在此分享、备忘下。
类已经我优化了几个地方使得兼容中文名称,和兼容主流浏览器下载显示的文件中文名称。
下载代码
HttpUtil.php
/** * HTTP工具类 * @author cxq 微知兮 */ class HttpUtil{ /** * 下载文件 * 可以指定下载显示的文件名,并自动发送相应的Header信息 * 如果指定了content参数,则下载该参数的内容 * @static * @access public * @param string $filename 下载文件名 * @param string $showname 下载显示的文件名 * @param string $content 下载的内容 * @param integer $expire 下载内容浏览器缓存时间 * @throws Exception * @return void */ static public function download($filename, $showname='',$cOntent='',$expire=180) { if(is_file($filename)){ $length = filesize($filename); }else if($content != ''){ $length = strlen($content); }else{ throw new Exception('文件不存在'); } if(empty($showname)){ $showname = $filename; } $showname = ltrim(substr($showname, strrpos($showname, '/')),"/"); if(!empty($filename)){ $type = mime_content_type($filename); }else{ $type = "application/octet-stream"; } $showname = urlencode($showname); $showname = str_replace("+", "%20", $showname); //发送Http Header信息 开始下载 header("Pragma: public"); header("Cache-control: max-age=".$expire); //header('Cache-Control: no-store, no-cache, must-revalidate'); header("Expires: " . gmdate("D, d M Y H:i:s",time()+$expire) . "GMT"); header("Last-Modified: " . gmdate("D, d M Y H:i:s",time()) . "GMT"); //header("Content-Disposition: attachment; filename=".$showname); $ua = $_SERVER['HTTP_USER_AGENT']; if(preg_match("/MSIE/", $ua)){ header('Content-Disposition: attachment; filename="' . $showname . '"'); }else if(preg_match("/Firefox/", $ua)){ header('Content-Disposition: attachment; filename*="utf8\'\'' . $showname . '"'); }else{ header('Content-Disposition: attachment; filename="' . $showname . '"'); } header("Content-Length: ".$length); header("Content-type: ".$type); header('Content-Encoding: none'); header("Content-Transfer-Encoding: binary" ); if($content == '' ){ readfile($filename); }else{ echo($content); } exit(); } /** * 采集远程文件 * @access public * @param string $remote 远程文件名 * @param string $local 本地保存文件名 * @return mixed */ static public function curlDownload($remote, $local) { $cp = curl_init($remote); $fp = fopen($local,"w"); curl_setopt($cp, CURLOPT_FILE, $fp); curl_setopt($cp, CURLOPT_HEADER, 0); curl_exec($cp); curl_close($cp); fclose($fp); } }
如果想更准确的Content-type类型 且 又版本不支持mime_content_type的话,请加入以下代码:
,//类定义结束 if( !function_exists ('mime_content_type')) { /** * 获取文件的mime_content类型 * @return string */ function mime_content_type($filename) { static $contentType = array( 'ai' => 'application/postscript', 'aif' => 'audio/x-aiff', 'aifc' => 'audio/x-aiff', 'aiff' => 'audio/x-aiff', 'asc' => 'application/pgp', //changed by skwashd -

使用方法
下载文件
HttpUtil::download("C:/Users/XQ/Desktop/1.jpg", "中文名字.jpg");
直接使用字符串作为文件下载
HttpUtil::download("", "1.txt", "写入文件里面的文字ABC123");
