you can use this function to get the version information into 1 array quickly.
<?php
function get_server_version($link){
  
$result = mysqli_get_server_version($link);
  
$main_version = round($result/10000, 0);
  
$minor_version = round(($result-($main_version*10000))/100, 0);
  
$sub_version = $result-($minor_version*100)-($main_version*10000);
  
   return array(
'main_version'=>$main_version, 'minor_version'=>$minor_version, 'sub_version'=>$sub_version, 0=>$result);
}
?>
