解压到

phpStudyPHPTutorialphpphp-7.2.1-ntsext

 php.int

extension=php_pdo_sqlsrv_72_nts_x64.dll
extension=php_sqlsrv_72_nts_x64.dll

安装 msodbcsql.msi 

这货要按照 64位

不然报错

This extension requires the Microsoft ODBC Driver for SQL Server. Access the following URL to download the ODBC Driver for SQL Server for x64

代码:sqlcon.php

 $serverName = "localhost";
 $connectionInfo = array( "Database"=>"DBWMS", "UID"=>"sa", "PWD"=>"123123");
 $conn = sqlsrv_connect( $serverName, $connectionInfo );
 if( $conn === false ) {
 die( print_r( sqlsrv_errors(), true));
 }
if( $conn === false ) {
    echo "Unable to connect.";
    die(var_dump(sqlsrv_errors(), true));
}

header("Content-type: text/html; charset=utf-8");
include "sqlcon.php";

$order = $_POST['OrderNum'];
//$order = "TY20171121103652803442";
$sql = "SELECT  ID,ExpressNum,OrderNum,NetWeight,GrossWeight FROM dbo.St_UserOrder where OrderNum=  '{$order}'";

$stmt = sqlsrv_query( $conn, $sql );

$stmt = sqlsrv_fetch_array($stmt);

echo json_encode($stmt);

INSERT INTO 语句

INSERT INTO 语句用于向表格中插入新的行。

语法

INSERT INTO 表名称 VALUES (值1, 值2,....)

我们也可以指定所要插入数据的列：

INSERT INTO table_name (列1, 列2,...) VALUES (值1, 值2,....)

php通过pdo连接sql sqlserver

public function __construct()
{

    $dbName = "sqlsrv:Server=Localhost;Database=tset";
    $dbUser = "sa";

    $dbPassword = "root";
    $this->pdo =  new PDO($dbName, $dbUser, $dbPassword);
}
对比

mysql

 $this->b =  $config;
    $this->pdo = new PDO('mysql:host=Localhost;port=3301;dbname=test', "123123", "123123");

}
双引号引发的

$sth = $this->pdo->prepare('SELECT * FROM xxx WHERE id =:id');//双引号失效

sql sever 
SELECT * FROM `pmw_St_UserOrder` WHERE id = :id  


mysql 

SELECT * FROM `pmw_St_UserOrder` WHERE id = :id

 $sth->execute(array(':id'=>'1'));


$results = $sth->fetchAll(PDO::FETCH_ASSOC);

$res = $db->query($sql);
$json_arr = array();
while ($row = $res->fetch()){
    $json_arr[]=$row;
}
