初始化一個數組一般有2種方法：一個是單獨給數組中的元素賦值；還有一種是把所有的元素一起初始化。
下面簡要介紹初始化數組的2種方法：
第一種方法：
$a["color"]="red";
$a["taste"]="sweet";
$a["shape"]="round";
$a["name"]="apple";
$a[3]=4;
第二種方法：
$a=array(
"color"=>"red",
"taste"=>"sweet",
"shape"=>"round",
"name"=>"apple",
3=>4);
這兩種方法的效果是相同的，不同的只是給元素賦值的方法不同。
下面是一個例子，需要注意的是，數組中元素的賦值是從第二個元素開始的。
