我怎样才能得到所有字母？
我需要在数组中得到所有字母,如：array(‘a’,’b’,’c’…);
使用
range这样的功能：
$letters = range('a','z');
print_r($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
)
