使用PHP强制下载PDF文件示例

话不多说，直接上代码。

复制代码 代码如下:

forceDownload("pdfdemo.pdf"); 

function forceDownload($filename) { 

if (false == file_exists($filename)) { 

return false; 

} 

// http headers 

header('Content-Type: application-x/force-download'); 

header('Content-Disposition: attachment; filename="' . basename($filename) .'"'); 

header('Content-length: ' . filesize($filename)); 

// for IE6 

if (false === strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE 6')) { 

header('Cache-Control: no-cache, must-revalidate'); 

} 

header('Pragma: no-cache'); 

// read file content and output 

return readfile($filename);; 

}
