<?<span php 

</span><span //</span><span 定义一个字符串数组</span>
<span $fruit</span> = <span array</span>(\"<span apple\",\"orange\");
//引用数组的值
</span><span $fruit</span><span [0];//代表的值是apple
</span><span $fruit</span><span [1];//代表的值是orange
//注意,数组的索引是从0开始的,学过c 和java 的人都知道呀。

//定义一个数值型的数组
</span><span $number</span><span  = array(1,2,3,4,5);//引用数组的值同上

//定义一个符合型的数组
</span><span $mix</span><span  = array(1,\"example\",\"hello\",2.5);//引用数组的值同上

//还可以用键值方式定义数组
</span><span $ex</span><span  = array(\"a\"=>\"水果\",\"b\"=>\"汽车\");
//可以这样去引用
</span><span $ex</span><span [\"a\"];//对应的值就是水果
</span><span $ex</span><span [\"b\"];//对应的值就是汽车
//也可以创建这样的键值符合型的数组
