php php爆炸所有字符

php explode all characters

提问by qwertymk

I'm looking for the equivalent of what in js would be 'this is a string'.split('')for PHP.

我正在寻找相当于 js'this is a string'.split('')中 PHP 的内容。

If I try $array = explode('', 'testing');I get an error Warning: explode() [function.explode]: Empty delimiter in

如果我尝试$array = explode('', 'testing');我得到一个错误Warning: explode() [function.explode]: Empty delimiter in

Is there another way to do this?

有没有另一种方法可以做到这一点？

As indicated by your error, exploderequires a delimiter to split the string. Use str_splitinstead:

如您的错误所示，explode需要一个分隔符来拆分字符串。使用str_split来代替：

$arr = str_split('testing');

Output

输出

Array
(
    [0] => t
    [1] => e
    [2] => s
    [3] => t
    [4] => i
    [5] => n
    [6] => g
)

Use the str_splitfunction.

使用该str_split功能。

$array = str_split( 'testing');

$string = "TEST";

echo $string[0];  // This will display T

There is no need to explode it

没必要炸
