在安装PHP时，我在Cygwin中执行mkdir之后遇到了'缺少操作数'

While attempting to make sure that $CVSROOT existed, I executed

mkdir $CVSROOT

only to find the error:

'missing operand'

Try:

(The number is the permission you set)

mkdir("$CVSROOT", 0700);

And if it should be a string not a variable use:

mkdir('$CVSROOT', 0700);
