个月阵列不显示正确的值

我有个月阵列等个月阵列不显示正确的值

$month = array(
    01 => "January", 
    02 => "February", 
    03 => "March", 
    04 => "April", 
    05 => "May", 
    06 => "June", 
    07 => "July", 
    08 => "August", 
    09 => "September", 
    10 => "October", 
    11 => "Novemeber", 
    12 => "December" 
);

但是当我的print_r此它显示这样

Array 
(
    [1] => January 
    [2] => February 
    [3] => March 
    [4] => April 
    [5] => May 
    [6] => June 
    [7] => July 
    [0] => September 
    [10] => October 
    [11] => Novemeber 
    [12] => December 
)

它显示七重峰为0和八月份是不显示。

任何人都可以告诉我这是什么问题。

Nubmber从0开始被解释为octal constats。

由于8和9是不是一个有效的数字八进制，08和09是无效号码，都解释为只是0。 “08”是字符串，即使是在算术运算的情况下，将被解释为正常的十进制整数：

"echo '08'+'08'; // 16

因此使用字符串应该是您的情况是安全的。
