本文实例讲述了PHP通过修改header强制图片下载的方法。分享给大家供大家参考。具体实现方法如下:
PHP;">
function downloadFile($file){
$file_name = $file;
$mime = 'application/force-download';
header('Pragma: public'); // required
header('Expires: 0'); // no cache
header('Cache-Control: must-revalidate,post-check=0,pre-check=0');
header('Cache-Control: private',false);
header('Content-Type: '.$mime);
header('Content-Disposition: attachment; filename="'.basename($file_name).'"');
header('Content-Transfer-Encoding: binary');
header('Connection: close');
readfile($file_name); // push it out
exit();
}
希望本文所述对大家的PHP程序设计有所帮助。
