You will want to use str_split().
您将需要使用 str_split()。
$result = str_split('abcdef');

Don't know if you're aware of this already, but you may not need to do anything (depending on what you're trying to do).
不知道您是否已经意识到这一点，但您可能不需要做任何事情（取决于您要做什么）。
$string = "abcdef";
echo $string[1];
//Outputs "b"
So you can access it like an array without any faffing if you just need something simple.
因此，如果您只需要一些简单的东西，就可以像数组一样访问它而无需任何处理。

You can use the str_split() function:
您可以使用 str_split() 函数：
$value = "abcdef";
$array = str_split($value);
If you wish to divide the string into array values of different amounts you can specify the second parameter:
如果您希望将字符串分成不同数量的数组值，您可以指定第二个参数：
$array = str_split($value, 2);
The above will split your string into an array in chunks of two.
以上将您的字符串分成两个块的数组。
回答by Gazler
$result = "abcdef";
$result = str_split($result);
There is also an optional parameter on the str_split function to split into chunks of x characters.
str_split 函数还有一个可选参数，用于拆分为 x 字符块。

With the help of str_split function, you will do it.
在 str_split 函数的帮助下，你会做到的。
Like below::
如下图：
<?php
$result = str_split('abcdef',1);
echo "<pre>";
print_r($result);
?>

best you should go for "str_split()", if there is need to manual Or basic programming,
最好你应该选择“ str_split()”，如果需要手动或基本编程，
$string = "abcdef";
$resultArr = [];
$strLength = strlen($string);
for ($i = 0; $i < $strLength; $i++) {
$resultArr[$i] = $string[$i];
}
print_r($resultArr);
Output:
输出：
Array
(
[0] => a
[1] => b
[2] => c
[3] => d
[4] => e
[5] => f
)
