PHP MS SQL - 致命错误：调用未定义的函数sqlsvr_connect（）

Question

Good morning. I am trying to set up a php development environment but I keep running in circles chasing down answers that have not worked by searching.

The error I get when trying to run the test php file in Php Designer or after saving it and running it in Chrome or Firefox to connect to my local MS SQL Express db is:

Fatal Error: Call to undefined function sqlsvr_connect()

I am using:

1. Xampp Control Panel V3.2.2
2. Apache 2.0 Handler
3. PHP Version 7.2.5 (x86)
4. MS SQL Express 2017 RTM
5. Php Designer 8.1.2

What I think are the correct MS SQL drivers for PHP php_pdo_sqlsrv_72_ts_x86.dll and php_sqlsrv_72_ts_x86.dll Both are stored in C:\xampp\php\ext

The code I'm using in the test.php:

$serverName = "DESKTOP-1FK6JRL\\SQLEXPRESS"; //serverName\instanceName
$connectionInfo = array( "Database"=>"testdb", "UID"=>"myusername", "PWD"=>"MyPassword");
$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));
}

This is my Apache error log:
