And an error: Connection could not be established.
I have installed ODBC driver.我已经安装了 ODBC 驱动程序。
Connection.php:连接.php：
<?php
$servername = "server_ip";
$connectionInfo=array( "Database"=>"Workflow", "UID"=>"admin",
"PWD"=>"pass");
$conn=sqlsrv_connect($servername, $connectionInfo);
$ID = $_POST['id'];
$Date = $_POST['date'];
$sql = "INSERT INTO T1 (ID,Date) VALUES ('$ID','$Date')";
if(mysqli_query($conn,$sql)) {
echo "Connection established.<br />";
}else{
echo "Connection could not be established.<br/>";
die(print_r(sqlsrv_errors(), true));
}

You use functions from two different PHP extensions - sqlsrv_ and mysqli_ .您使用来自两个不同 PHP 扩展的函数 - sqlsrv_和mysqli_ 。 To connect to MS SQL Server, use sqlsrv_ functions, they are part of PHP Driver for SQL Server .要连接到 MS SQL Server，请使用sqlsrv_函数，它们是PHP Driver for SQL Server 的一部分。
Also, consider the following:另外，请考虑以下事项：
- use prepared statements:使用准备好的语句：
- surround columns names with
[], if they are reserved keywords用[]包围列名，如果它们是保留关键字
Try with this connection.php :试试这个connection.php ：
<?php
# Connection
$servername = "server_ip";
$connectionInfo = array(
"Database"=>"Workflow",
"UID"=>"admin",
"PWD"=>"pass"
);
$conn = sqlsrv_connect($servername, $connectionInfo);
if( $conn === false ) {
echo "Error (sqlsrv_connect): ".print_r(sqlsrv_errors(), true);
exit;
}
# Parameters
$id = $_POST['id'];
$date = $_POST['date'];
$params = array(&$id, &$date);
# Statement
$sql = "INSERT INTO T1 (ID, [Date]) VALUES (?, ?)";
$stmt = sqlsrv_prepare($conn, $sql, $params);
if ($stmt === false) {
echo "Error (sqlsrv_prepare): ".print_r(sqlsrv_errors(), true);
exit;
}
if (sqlsrv_execute($stmt)) {
echo "Statement executed.\n";
} else {
echo "Error (sqlsrv_execute): ".print_r(sqlsrv_errors(), true);
}
# End
sqlsrv_free_stmt($stmt);
sqlsrv_close($conn);
?>
