First of all, I'm really a noob. (Feel sorry) Secondly, I tried to connect php to mssql server. Third, I have installed sqlsrv, pdo_sqlsrv and msodbcsql.msi But still getting error message when trying to connect

My php version is 8.0.10, x64; mssql server 2012.

My php code for testing the connection:

<?php
$serverName = "10.xxx.xx.148";
$connectionInfo = array( "Database"=>"zzzz", "UID"=>"ww","PWD"=>"123cccc");
$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));}
?>

Then I got an error and was instructed to install msodbcsql.msi, I installed it as instructed. But then it shows new errors which I can't solve.

Array ( [0] => Array ( [0] => 08001 [SQLSTATE] => 08001 1 => -2146893019 [Code] => -2146893019 2 => [Microsoft][ODBC Driver 18 for SQL Server] SSL Provider: The certificate chain was issued by an untrusted authority.

Additional information: There is no problem when I connect dbeaver (different computer) to mssql server (same server).

Thank you in advance
