php - 使用 PHP 将 UCS-2 文件转换为 UTF-8

我有一个客户端提供的 CSV 文件，必须使用 PHP 解析并插入到数据库中。

在将数据插入数据库之前，我想将其转换为 UTF-8，但我似乎无法找到方法。

这就是我试图检测文件编码的原因:

$ enca -d -L zh ./artigos.txt
    ./artigos.txt: Universal character set 2 bytes; UCS-2; BMP
    CRLF line terminators
    Byte order reversed in pairs (1,2 -> 2,1)

我尝试使用 iconv 函数，但它弄乱了转换并显示结果与原始字符不同。

文件的第一行(base64 编码):

最佳答案

这似乎有效(小端)，尽管您没有包含任何非 ascii 字符

$t=base64_decode($s);
echo iconv('UCS-2LE', 'UTF-8', substr($t, 0, -1));//last byte was invalid
