Php User agent

http://dk.php.net/manual/da/reserved.variables.php#reserved.variables.server

du bruger den predefinerede variabel $_SERVER

med den kan du på det link, jeg sendte før, se, hvilke informationer du kan få fat i

hvis du gerne vil vise browser info kan du fx

<?
echo $_SERVER['HTTP_USER_AGENT'];
?>

Tak Radio.. men kan man ikke stille det lidt pænere op fx
Browser: Firefox
System: Windows xp

o.s.v

jo, det kan du godt, men, så skal du jo bare ind og dissikere i den output streng du får.. finde ud af om det er en gecko, hvis det er det, så skal der skrives "firefox" osv osv

Radion kan du ikke lige skrive et svar så jeg kan give dig point

hep.

fandt lige en funktion til dig.. den bestemmer primært browser, men, det kan være den kan hjælpe dig :)
