问题描述
我有以下代码不适用于UTF-8字符.我该如何解决?
I have the following code which is not working with UTF-8 characters. How can I fix it?
$seed = preg_split('//u', $seed, -1, PREG_SPLIT_NO_EMPTY);
$seed = str_split('АБВГДЕЖЗ'); // and any other characters
shuffle($seed); // probably optional since array_is randomized; this may be redundant
$code = '';
foreach (array_rand($seed, 5) as $k) $md5_hash .= $seed[$k];
//We don't need a 32 character long string so we trim it down to 5
$security_code = $code;
我已经尝试过以下代码:
I have tried this code:
$seed = preg_split('//u', $seed, -1, PREG_SPLIT_NO_EMPTY);
但它仍然无法正常工作.
but it is still not working.
推荐答案
您必须先创建变量$seed
并为其提供字符串值,然后才能将其用作preg_split
的第二个参数:
You must create the variable $seed
and give it a string value before you can use it as the second parameter of preg_split
:
$seed = 'АБВГДЕЖЗ';
$seed = preg_split('//u', $seed, -1, PREG_SPLIT_NO_EMPTY);
print_r($seed)
的输出将是:
Array
(
[0] => А
[1] => Б
[2] => В
[3] => Г
[4] => Д
[5] => Е
[6] => Ж
[7] => З
)
我希望您的其余代码都能正常工作.
I hope the rest of your code will work just fine.
