<?php
if ( preg_match('#OPERA(/| )([0-9].[0-9]{1,2})#', strtoupper($_SERVER["HTTP_USER_AGENT"]), $log_version) ){
$USER_BROWSER_AGENT = 'OPERA';
}  
if ( preg_match('#MSIE(/| )([0-9].[0-9]{1,2})#', strtoupper($_SERVER["HTTP_USER_AGENT"]), $log_version) ){
$USER_BROWSER_AGENT = 'MSIE';
}  
PRINT $USER_BROWSER_AGENT;
?>
