php中如何初始化一个数组
数组
初始化一个数组一般有2种方法:一个是单独给数组中的元素赋值;还有一种是把所有的元素一起初始化。
下面简要介绍初始化数组的2种方法:
第一种方法:
$a["color"]="red";
$a["taste"]="sweet";
$a["shape"]="round";
$a["name"]="apple";
$a[3]=4;
第二种方法:
$a=array(
"color"=>"red",
"taste"=>"sweet",
"shape"=>"round",
"name"=>"apple",
3=>4);
这两种方法的效果是相同的,不同的只是给元素赋值的方法不同。
下面是一个例子,需要注意的是,数组中元素的赋值是从第二个元素开始的。
