PHP:将字符串拆分为数组，就像没有分隔符的爆炸一样 [英] PHP: Split string into array, like explode with no delimiter

问题描述

我有一个字符串，例如:

I have a string such as:

0123456789"

"0123456789"

并且需要将每个字符拆分成一个数组.

and need to split EACH character into an array.

我真的试过了:

explode('', '123545789');

但它给了我显而易见的:警告:爆炸中没有定义分隔符) ..

But it gave me the obvious: Warning: No delimiter defined in explode) ..

我怎么会遇到这个?我看不到任何方法，尤其是一个函数

How would I come across this? I can't see any method off hand, especially just a function

推荐答案

$array = str_split("0123456789bcdfghjkmnpqrstvwxyz");

str_split 接受可选的第二个参数，块长度(默认1)，因此您可以执行以下操作:

str_split takes an optional 2nd param, the chunk length (default 1), so you can do things like:

$array = str_split("aabbccdd", 2);

// $array[0] = aa
// $array[1] = bb
// $array[2] = cc  etc ...

您还可以通过将字符串视为数组来获取部分字符串:

You can also get at parts of your string by treating it as an array:

$string = "hello";
echo $string[1];

// outputs "e"
