手册上有说明 shell_exec函数下面的解说 Got the error "Unable to execute..." when trying to run an external program with shell_exec under Windows XP, IIS 5, php 4.3.7 Solved by giving the IIS user (IUSR_...) execution privileges on the system file %systemroot%\system32\cmd.exe This should be used carefully because may represent a server's security hole. 给cmd.exe赋予IUSER_.......用户可以读运行的权限，问题解决。 赋予权限 cacls c:\windows\system32\cmd.exe /e /c /p IUSER_.....:r 撤销权限 cacls c:\windows\system32\cmd.exe /e /c /r IUSER_.....
