一、配置环境

　　1、配置好SqlServer的登录名：sc。参考：https://jingyan.baidu.com/article/8cdccae9452b3c315513cd52.html

　　2、下载 php_pdo_sqlsrv_74_ts_x64.dll 和 php_sqlsrv_74_ts_x64.dll两个文件并放到 php 的ext目录下。下载地址：https://www.zhaodll.com/dll/p/201905/343232.html

　　3、在你的php.ini文件中加上

extension=php_pdo_sqlsrv_74_ts_x64.dll
extension=php_sqlsrv_74_ts_x64.dll

　　4、重启Apache服务器。

　　5、测试：

$serverName = "localhost"; //数据库服务器地址
$uid = "sa";     //数据库用户名
$pwd = "lxy208751"; //数据库密码
$connectionInfo = array("UID" => $uid, "PWD" => $pwd, "Database" => "Students");
$conn = sqlsrv_connect($serverName, $connectionInfo);
if ($conn == false) {
    echo "连接失败！";
    var_dump(sqlsrv_errors());
    exit;
} else {
    echo "链接成功";
}

 

 

二、编码设置

（注：由于sql server 不支持UTF8，当使用varchar保存汉字时，会出现乱码。需要转换。）

　　1、从数据库查出来的数据编码“GBK”，一般我们有的是“UTF-8”,所以需要转换成“UTF-8”。

function toU8($str){
    return iconv('GBK', 'UTF-8', $str);
}

　　2、从程序代码中的变量插入的数据库时，需要将变量的编码改成“GBK”才能插入数据库。

function toGBK($str){
    return iconv('UTF-8', 'GBK', $str);
}

三、学生信息管理系统

　　1、index.php

 
<?php

include('./conn/conn.php');
$sql="select * from student";
$result = sqlsrv_query( $conn, $sql ) or die("数据查询失败！");

if(!empty($_GET)){
    $delete=$_GET['delete'];
    if($delete='1'){
        echo "<script>alert('删除成功！');</script>";

    }else{
        echo "<script>alert('删除失败！');</script>";
    }

}
function toU8($str){
    return iconv('GBK', 'UTF-8', $str);
}

?>
