8.5 陣列

　　使用 PHP 建立陣列有以下幾種方法：
以數字為索引值 
<?php
    $name = array("Chen", "Lin", "Jang", "Lee", "Wang");
?>
 
<?php
    $name[0] = "Chen";
    $name[1] = "Lin";
    $name[2] = "Jang";
    $name[3] = "Lee";
    $name[4] = "Wang";
?>
以字串為索引值 
<?php
    $name = array(
        "a" => "Chen",
        "b" => "Lin",
        "c" => "Jang",
        "d" => "Lee",
        "e" => "Wang"
    );
?>
 
<?php
    $name["a"] = "Chen";
    $name["b"] = "Lin";
    $name["c"] = "Jang";
    $name["d"] = "Lee";
    $name["e"] = "Wang";
?>
　　至於要如何從陣列中取出資料呢？除了使用索引值外，PHP 還提供了多種簡單方便的函式，例如 list()：
// 只有在以數字為索引值時才能使用 list()
$arr = array('one', 'two', 'three');
list($a, $b, $c) = $arr;
echo "$a plus $b equals $c";
