如何在PHP中获取所有alpabetic字母？

Question

我怎样才能得到所有字母？

我需要得到一个数组中的所有字母,如: array('a','b','c'...);

Answer 1

使用这样的range功能:

$letters = range('a', 'z');
print_r($letters);

结果:

Array
(
    [0] => a
    [1] => b
    [2] => c
    [3] => d
    [4] => e
    [5] => f
    [6] => g
    [7] => h
    [8] => i
    [9] => j
    [10] => k
    [11] => l
    [12] => m
    [13] => n
    [14] => o
    [15] => p
    [16] => q
    [17] => r
    [18] => s
    [19] => t
    [20] => u
    [21] => v
    [22] => w
    [23] => x
    [24] => y
    [25] => z
)

Answer 2

使用范围来做到这一点,这很容易.

$az = range('a', 'z');
