我有一个非常简单直接的问题要做。我需要从我的 MySQL 服务器下载 3 种不同类型的数据：

：图像、音频、视频

所以我正在经历一些深入的 PHP 事情，我发现了这两段代码：

声音的：

<?php
    // Connect to database
    @mysql_connect("mysql.server.com.br","user","pass01");
    @mysql_select_db("database01") or die( "Unable to select database");

    // Find out about latest image

    $gotten = @mysql_query("SELECT audio_content AS audio_in_blob FROM database01.audio_content WHERE content_id = 'id01';");
    if ($row = @mysql_fetch_assoc($gotten)) {
        $bytes = $row[ "audio_in_blob" ];
    } 
    else {
        echo "hoe!";
        $errmsg = 'Could not run query: ' . mysql_error();
        $title = "no database image available";
    }

    // If this is the image request, send out the image

    header("Content-type: audio/mp3");
    echo $bytes;
    exit ();
?>

视频：

<?php

    // Connect to database

    @mysql_connect("mysql.server.com.br","user","pass01");
    @mysql_select_db("database01") or die( "Unable to select database");

    // Find out about latest image

    $gotten = @mysql_query("SELECT video_content AS video_in_blob FROM database01.video_content WHERE content_id = 'id01';");
    if ($row = @mysql_fetch_assoc($gotten)) {
        $bytes = $row[ "video_in_blob" ];
    } 
    else {
        echo "hoe!";
        $errmsg = 'Could not run query: ' . mysql_error();
        $title = "no database image available";
    }

    // If this is the image request, send out the image

    header("Content-type: video/mpeg");
    echo $bytes;
    exit ();
?>

但是这些方法只是在浏览器中显示 blob 而不会下载它们。我能做些什么？我需要下载这些 blob 并使其可用于视频/照片/音频显示。

干杯。
