PHP 读取或生成Unicode csv文件（PHP读取淘宝CSV文件出现乱码解决方案）

=======先介绍下BOM==============

Bytes	Encoding Form
EF BB BF UTF-8
FF FE UTF-16 aka UCS-2, little endian
FE FF UTF-16 aka UCS-2, big endian
00 00 FF FE UTF-32 aka UCS-4, little endian.
00 00 FE FF UTF-32 aka UCS-4, big-endian.

=======================

读取 unicode csv 文件

 

function fopen_utf8($filename){
    $encoding='';
    $handle = fopen($filename, 'r');
    $bom = fread($handle, 2);
//    fclose($handle);
    rewind($handle);
 
    if($bom === chr(0xff).chr(0xfe)  || $bom === chr(0xfe).chr(0xff)){
            // UTF16 Byte Order Mark present
            $encoding = 'UTF-16';
    } else {
        $file_sample = fread($handle, 1000) + 'e'; //read first 1000 bytes
        // + e is a workaround for mb_string bug
        rewind($handle);
 
        $encoding = mb_detect_encoding($file_sample , 'UTF-8, UTF-7, ASCII, EUC-JP,SJIS, eucJP-win, SJIS-win, JIS, ISO-2022-JP');
    }
    if ($encoding){
        stream_filter_append($handle, 'convert.iconv.'.$encoding.'/UTF-8');
    }
    return  ($handle);
}

 

生成 unicode csv （此php文件一定要是无BOM的UTF-8编码文件）

$content=iconv("UTF-8","UTF-16LE",$content);
$content = "\xFF\xFE".$content; //添加BOM
header("Content-type: text/csv;charset=UTF-16LE") ;
header("Content-Disposition: attachment; filename=test.csv");
 
再介绍一个 操作 ANSI 编码 以 "," 隔开的 操作类
