php中可以通過(guò)設(shè)置header的content-type，強(qiáng)制用戶下載內(nèi)容，而非直接在瀏覽器中打開(kāi)，如下代碼實(shí)現(xiàn)：

downloadFile.php

<?php
$filename = $_GET['file']; //Get the fileid from the URL
// Query the file ID
$query = sprintf("SELECT * FROM tableName WHERE id = '%s'",mysql_real_escape_string($filename));
$sql = mysql_query($query);
if(mysql_num_rows($sql) > 0){
    $row = mysql_fetch_array($sql);
    // Set some headers
    header("Pragma: public");
    header("Expires: 0");
    header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
    header("Content-Type: application/force-download");
    header("Content-Type: application/octet-stream");
    header("Content-Type: application/download");
    header("Content-Disposition: attachment; filename=".basename($row['FileName']).";");
    header("Content-Transfer-Encoding: binary");
    header("Content-Length: ".filesize($row['FileName']));

    @readfile($row['FileName']);
    exit(0);
}else{
    header("Location: /");
    exit;
}
?>

files.php

<a href="downloadFile.php?file=7383">Download</a>
