特殊字符（ex“。”）无法从PHP中读取CSV

Question

我正在为电子商务网站制作导入/导出功能。导入库存运行良好的功能。但那里存在问题。当我在库存字段中写入任何特殊字符（例如“。”，“，”）时，此字符将替换为“??”。

那么，任何人都可以帮我解决这个问题吗？

header( "Content-Type: text/html; charset=utf-8");
        $csvContent = file_get_contents( $fileName );
        $encoding = mb_detect_encoding( $csvContent, 
                                        array("UTF-8","UTF-32","UTF-32BE","UTF-32LE","UTF-16","UTF-16BE","UTF-16LE"), 
                                        TRUE );

        if( $fileEncoding !== "UTF-8" ) {
             $csvContent = mb_convert_encoding($csvContent, "UTF-8", $fileEncoding );
        }

        foreach( explode( PHP_EOL, $csvContent ) as $item ) {
           var_dump($item );
        }
