Question

我有ampp3.9-PHP7.3和SQLserver-2014 12.0.2269.0。我无法连接数据库。我得到以下错误

致命错误：未捕获错误：调用未定义的函数sqlsrv_connect((，位于E:\Ampps\Apps\www\backend-scripts\database.php中：4堆栈跟踪：在E:\Ampps\Apps\www\backend中引发#0｛main｝第4行的scripts\database.php

这是我的代码

<?php
$serverName = "DESKTOP-VDSPQT9"; //serverNameinstanceName
$connectionInfo = array( "Database"=>"railway", "UID"=>"sa", "PWD"=>"bhanu123");
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn ) {
echo "Connection established.<br />";
}else{
echo "Connection could not be established.<br />";
die( print_r( sqlsrv_errors(), true));
}
?>
