可能重复:
php数组表现奇怪,键值为07和08

我在PHP中发现了一些奇怪的东西,如果我使用数字数组,第8个数组会被忽略,这时当我把'Cherry'放入$ fruit [08]时,php接缝就会跳过它.

这是怎么回事 ？这是一个错误还是别的什么.

<pre>
<?php

$fruit[01] = "Apples";
$fruit[02] = "Pears";
$fruit[03] = "Bananas";
$fruit[04] = "Grape";
$fruit[05] = "Orange";
$fruit[06] = "Peach";
$fruit[07] = "Lemon";
$fruit[08] = "Cherry";
$fruit[09] = "Mango";

print_r($fruit);

?>
</pre>

输出:

Array
(
    [1] => Apples
    [2] => Pears
    [3] => Bananas
    [4] => Grape
    [5] => Orange
    [6] => Peach
    [7] => Lemon
    [0] => Mango
)
