PHP连接SQLServer echo输出中文汉字显示乱码解决方法

1、查询结果有中文会显示乱码。

解决方法一（较简单，建议使用）：

在php文件最开头写上：

header('Content-type: text/html; charset=UTF8'); // UTF8不行改成GBK试试，与你保存的格式匹配

<?php
header("content-type:text/html;charset=GBK");  //设置编码

2、查询前对SQL转码

$sql = "SELECT '是'='是'"; 
$sql=iconv('UTF-8','GBK',$sql);

3、查询结果对含中文列转码

$stmt = sqlsrv_query( $conn, $sql);
if($stmt){
    while( $row = sqlsrv_fetch_array( $stmt, SQLSRV_FETCH_NUMERIC) ) {
        echo iconv('GBK','UTF-8',$row[0])."<br />";
    }
}
