Connection Strings in Laravel - php

Question

In Laravel, I set my SQL Server connection string like this in the .env file: -
DB_CONNECTION=mssql
DB_HOST=sql-server123.database.windows.net
DB_PORT=1433
DB_DATABASE=dev-db-123
DB_USERNAME=user123
DB_PASSWORD=pass123
But now I'd like to format my connection string to connect to SQL Azure using the system-assigned managed identity provided by Azure Cloud.
As a test, I used Microsoft's example to connect using a System Managed Identity: -
https://learn.microsoft.com/en-us/sql/connect/php/azure-active-directory?view=sql-server-ver15
<?php
$azureServer = 'myazureserver.database.windows.net';
$azureDatabase = 'myazuredatabase';
$connectionInfo = array('Database'=>$azureDatabase,
'Authentication'=>'ActiveDirectoryMsi');
$conn = sqlsrv_connect($azureServer, $connectionInfo);
if ($conn === false) {
echo "Could not connect with Authentication=ActiveDirectoryMsi (system-assigned).\n";
print_r(sqlsrv_errors());
} else {
echo "Connected successfully with Authentication=ActiveDirectoryMsi (system-assigned).\n";
$tsql = "SELECT ##Version AS SQL_VERSION";
$stmt = sqlsrv_query($conn, $tsql);
if ($stmt === false) {
echo "Failed to run the simple query (system-assigned).\n";
print_r(sqlsrv_errors());
} else {
while ($row = sqlsrv_fetch_array($stmt, SQLSRV_FETCH_ASSOC)) {
echo $row['SQL_VERSION'] . PHP_EOL;
}
sqlsrv_free_stmt($stmt);
}
sqlsrv_close($conn);
}
?>
Where in Laravel can I set the connection string to use: -
'Authentication'=>'ActiveDirectoryMsi'

Try this and let me know:
DB_CONNECTION=mssql
DB_HOST=sql-server123.database.windows.net
DB_PORT=1433
DB_DATABASE=dev-db-123
DB_USERNAME=user123
DB_PASSWORD=pass123
AUTHENTICATION=ActiveDirectoryMsi
or in alternative:
DB_AUTHENTICATION=ActiveDirectoryMsi
