PHP做下载文件的方法
<?php header("Content-Type: application/force-download"); header("Content-Disposition: attachment; filename=ins.jpg"); readfile("imgs/test_Zoom.jpg"); ?>
第一行代码是强制下载;
第二行代码是给下载的内容指定一个名字;
第三行代码是把下载的内容读进文件中。
Example #1 Forcing a download using readfile()
<?php $file = 'monkey.gif'; if (file_exists($file)) { header('Content-Description: File Transfer'); header('Content-Type: application/octet-stream'); header('Content-Disposition: attachment; filename='.basename($file)); header('Content-Transfer-Encoding: binary'); header('Expires: 0'); header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); header('Pragma: public'); header('Content-Length: ' . filesize($file)); ob_clean(); flush(); readfile($file); exit; } ?>
