define array

这个是一个php关于数组的例子,简要的说明了数组的基本使用,示例中加放了注释

复制代码 代码如下:

//定义一个字符串数组
$fruit = array(\"apple\",\"orange\");
//引用数组的值
$fruit[0];//代表的值是apple
$fruit[1];//代表的值是orange
//值得注意的是,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
$number = array(1,2,3,4,5);//引用数组的值同上

//定义一个符合型的数组
$mix = 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
$ex = array(\"a\"=>\"水果\",\"b\"=>\"汽车\");
//可以这样去引用
$ex[\"a\"];//对应的值就是水果
$ex[\"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
