使用PHP强制下载PDF文件示例_PHP

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);; 
} 
 
为了方便，我写了一个函数forceDownload()，然后通过调用该函数即可。
