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 : stringtype 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PHP str_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。
