求一个类似于Aria2的工具

win8

有个Apache+MySQl+PHP的服务器，我只有FTP和phpmadmin的界面，不允许直接做代理服务器使用，空间配额我偶尔想用作离线下载墙边的http、ftp资源，有这样现成或者改改就能用的公具吗？我是码盲，自己感觉是下载可以用PHP調wget来做

RaidenII

恐怕难。php调用外部命令一般通过shell_exec、exec、system、passthrough等等几个函数，而这几个函数一般出于安全原因是禁用的。你可以写个phpinfo传到服务器上看看disable_functions禁用了哪些函数。

这个可能是chroot过或者httpd关掉了那些函数……试试用php-curl来实现吧，用exec调用wget或者fopen打开url都不是很安全。
