PHP | 将字符串转换为字符数组
给定一个字符串，我们必须将其转换为字符数组。
示例
Input:
"WubbalubbaDubDub"
Output:
Array
(
[0] => W
[1] => u
[2] => b
[3] => b
[4] => a
[5] => l
[6] => u
[7] => b
[8] => b
[9] => a
[10] => D
[11] => u
[12] => b
[13] => D
[14] => u
[15] => b
)PHP代码将字符串转换为字符数组
<?php //PHP代码将字符串转换为 //字符数组 //输入字符串 $input = "WubbalubbaDubDub"; //将字符串转换为字符数组 //使用str_split() $output = str_split($input); //打印类型 echo "type of input : " .gettype($input) ."<br/>"; echo "type of output: " .gettype($output) ."<br/>"; //打印结果 echo "input: " .$input ."<br/>"; echo "output: " ."<br/>"; print_r($output); ?>
输出结果
type of input : string
type of output: array
input: WubbalubbaDubDub
output:
Array
(
[0] => W
[1] => u
[2] => b
[3] => b
[4] => a
[5] => l
[6] => u
[7] => b
[8] => b
[9] => a
[10] => D
[11] => u
[12] => b
[13] => D
[14] => u
[15] => b
)说明：
我们使用PHPstr_split()函数，以单个字符从一个字符串分割成字符数组。字符串（$input）被拆分为单个字符，并存储到（$output）中，然后使用print_r()函数以数组形式打印。
