PHPCrawl爬蟲庫抓取酷狗歌單

本人看了網路爬蟲相關的視頻後，蠢蠢欲動，也想爬點什麼。最近Facebook上表情包大戰很激烈，就想著把所有表情包都爬下來，卻一時沒有找到合適的VPN，因此只好仿照視頻爬歌單，把酷狗最近一月精選歌曲和簡單介紹抓取到本地。代碼寫得有點亂，自己不是很滿意，並不想放上來丟人現眼。不過轉念一想，這好歹是自己第一次爬蟲，記錄一下人生中的某個“第一次”有何不可？於是...就有了如下不堪入目的代碼~~~（ps.我是直接增、刪、改PHPCrawl爬蟲庫中給的example.php檔案。由於抓取的資料量較小，所以沒有考慮多進程什麼的，不過我看了一下PHPCrawl的文檔，發現PHPCrawl庫已經把我能想到的功能都封裝好了，實現起來很方便，YY著下次有時間就用它爬一些“大資料”，再用視覺化檢視進行資料分析，想想還有點小激動呢~）
