PHP文件下载页简单实现
function get_extension($file){
return substr(strrchr($file, '.'), 1);
}
function get_name($path){
return substr(strrchr($path, '/'), 1);
}
function getImage($url,$fileName="") {
$fbufsize = 8096;
$ext = get_extension($url);
$fileName = get_name($url);
$type = array(
'gif' => 'image/gif',
'jpeg' => 'image/jpeg',
'jpg' => 'image/jpeg',
'jpe' => 'image/jpeg',
'png' => 'image/png',
);
$imgType = isset($type[$ext])?$type[$ext]:die("类型不符");
header('Content-Description: File Transfer');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header("Content-type: ".$imgType);
header("Content-Transfer-Encoding: binary");
header('Content-Disposition: attachment; filename="'.$fileName.'"');
header("Content-Length:" . getimagesize($url)."\n\n" );
$fp = fopen($url,"r");
while(!feof($fp)) {
print(fread($fp,$fbufsize));
flush();
ob_flush();
}
fclose($fp);
exit;
}
getImage("http://www.lpfrx.com/wp-content/themes/ProSense/images/rss-feed-icon.jpg");
搭配jquery前后台一起处理还是很给力的，例如图片
$("img).click(function(){
var path = $(this).attr("src");
location.href="test.php?path="+path;
})
测试过了
无论下载什么格式，改一下就行了，特此备份，以便查阅
