PHP強制性文件下載

如果你需要下载特定的文件而不用另开新窗口，下面的代码片段可以帮助你。

function force_download($file)
{
    $dir      = "../log/exports/";
    if ((isset($file))&&(file_exists($dir.$file))) {
       header("Content-type: application/force-download");
       header('Content-Disposition: inline; filename="' . $dir.$file . '"');
       header("Content-Transfer-Encoding: Binary");
       header("Content-length: ".filesize($dir.$file));
       header('Content-Type: application/octet-stream');
       header('Content-Disposition: attachment; filename="' . $file . '"');
       readfile("$dir$file");
    } else {
       echo "No file selected";
    }
}

用法：

force_download("image.jpg");
?>
