如何使用PHP和phpSpider实现音乐网站的歌曲数据抓取？

<?php
require 'vendor/autoload.php';
use phpspidercorephpspider;
$spider = new phpspider();

$spider->config['name'] = 'music_spider';
$spider->config['log_show'] = false;
$spider->config['host'] = 'https://music.example.com';
$spider->config['export'] = array(
    'type' => 'csv',
    'file' => './output/songs.csv',
);

$spider->add_scan_url('https://music.example.com/songs');
$spider->on_scan_page = function($page, $content, $phpspider)
{
    $urls = array();
    // 解析歌曲列表页获取每首歌的详情页URL
    if (preg_match_all('/<a href="(/songs/d+)">/', $content, $out))
    {
        foreach ($out[1] as $url)
        {
            $urls[] = "https://music.example.com" . $url;
        }
    }
    return $urls;
};

$spider->on_extract_page = function($page, $data)
{
    $songs = array();
    // 解析歌曲详情页获取歌曲数据
    if (preg_match('/<h1>(.*?)</h1>/', $page['raw'], $out))
    {
        $song_name = $out[1];
        // 处理歌曲名
        $song_name = str_replace(' - ', ' ', $song_name);
        $songs['name'] = $song_name;
    }
    if (preg_match('/歌手：<a href=".*?">(.*?)</a>/', $page['raw'], $out))
    {
        $singer = $out[1];
        $songs['singer'] = $singer;
    }
    // 做其他数据处理和存储逻辑...

    return $songs;
};

$spider->start();
