1.概念: XML是一种Extensible Mark-up Language,事实上他不是一种mark-up语言,他 是一种用来定义更适合特定tasks的新mark-up语言的方法。他的工作原理是:为 DTDs(Document Type Definitions)定义了语法。一个DTD定义了文档中可以出 现的一系列的元素,元素的属性以及各元素之间的关系;他还定义了元素的强制 性与可选性

编写一个脚本,从一叠纸牌中随机抽出10张,并打印结果值。 a:该脚本应当先借助foreach循环构建一套52张牌。 b:外层循环负责按照花色遍历整套纸牌:梅花,方块,红桃,黑桃。内层循环则针对每一种花色遍历所有数字:A、1到10、J、Q、K。从各种花色获得的纸牌都将赋值到一个数组中。 c:使用rand()函数从上述数组中随机获得一张纸牌。这样做便能保证获得的10张纸牌互不重复。 [root
