PHP-将字符串转换为unicode [英] PHP - Convert string to unicode

问题描述

我正在处理

$source = mb_convert_encoding('test', "unicode", "utf-8");
$source = unpack('C*', $source);
var_dump($source);

返回：

array (size=8)
  1 => int 0
  2 => int 116
  3 => int 0
  4 => int 101
  5 => int 0
  6 => int 115
  7 => int 0
  8 => int 116

但我想要此返回值：

array (size=8)
  1 => int 116
  2 => int 0
  3 => int 101
  4 => int 0
  5 => int 115
  6 => int 0
  7 => int 116
  8 => int 0

我想在openssl函数中使用此返回值进行加密。只是 $ source 对我很重要，我编写了其他代码进行调试。

I want use this return in openssl function for encryption. just $source important to me, i write other code for debugging.

我该怎么办才能解决此问题？

What can i do to solve this problem?

推荐答案

Unicode不是真正的编码；它是总体标准的名称，主要由Microsoft用作UTF-16BE的别名，显然，PHP为此支持它。您期望的是UTF-16LE，因此请明确使用它：

"Unicode" is not a real encoding; it's the name of the overarching standard and used as an alias for UTF-16BE mostly by Microsoft, and apparently PHP supports it for that reason. What you expect is UTF-16LE, so use that explicitly:

$source = mb_convert_encoding('test', 'UTF-16LE', 'UTF-8');
