如果你的url链接是相对路径static/mapi.css，你想把他批量替换成绝对路径http://dev.baidu.com/wiki/static/map/cloud/static/mapi.css。那么，你可以这样做：写一个PHP文件，把需要替换的网址写进去。这个代码的意思就是，把#BASE_URL#替换成http://api.m

如果你的url链接是相对路径“static/mapi.css”，你想把他批量替换成绝对路径“http://dev.baidu.com/wiki/static/map/cloud/static/mapi.css”。那么，你可以这样做：

写一个PHP文件，把需要替换的网址写进去。

这个代码的意思就是，把#BASE_URL#替换成 http://api.map.baidu.com/lbsapi/cloud/ 。

这句话的意思是，把resource文件里的内容替换一遍，然后放到cloud文件夹里。FileUtil::copyDir("resource","cloud",true);

<span>php
</span><span>//</span><span>需要替换的关键字</span>
<span>$GLOBALS</span>["patterns"] = <span>array</span><span>(
    </span>"/#BASE_URL#/"<span>
);

</span><span>//</span><span>替换后的内容，和上面的匹配规则一一对应</span>
<span>$GLOBALS</span>["replacements"] = <span>array</span><span>(
   </span>"http://api.map.baidu.com/lbsapi/cloud/"
    <span>//</span><span>"http://172.22.168.178/lbsapi/"
    //"http://dev.baidu.com/wiki/static/map/cloud/"</span>
