<?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;
}
?>
以上代碼是下載代碼
接下來(lái)貼一段在線預(yù)覽pdf文件的代碼
復(fù)制代碼 代碼如下:
<?php
public function fddAction()
{
// get attachment location
$attachment_location = $_SERVER["DOCUMENT_ROOT"] . "/pdf/fdd/sample.pdf";
if (file_exists($attachment_location)) {
// attachment exists
// send open pdf dialog to user
header('Cache-Control: public'); // needed for i.e.
header('Content-Type: application/pdf');
header('Content-Disposition: inline; filename="sample.pdf"');
readfile($attachment_location);
die(); // stop execution of further script because we are only outputting the pdf
} else {
die('Error: File not found.');
}
}
?>
