//先登錄$cmd='net use \\\\192.168.1.255\\e$\\dtcms\\dmeo "password" /user:"administrator" /persistent:"YES"';exec($cmd);//再復制$cmd1='xcopy \\\\192.168.1.255\\e$\\dtcms\\dmeo E:\\work\\notfinish\\demo /D/E';exec($cmd1);已確定在cmd命令上是可以執行的。但是php運行時卻沒效果且安全模式已關閉。 如果命令中需要加入php變量，比如：$path=demo1.txt;$cmd1='xcopy \\\\192.168.1.255\\e$\\dtcms\\dmeo\\$path E:\\work\\notfinish\\demo /D/E';該怎么連接字符串和變量
