Using $http_user_agent in a conditional statement depending upon what client is being used, what are the possible values I should use? For example:
PHP Code:
<?php
if ($http_user_agent == "Internet Explorer" or "Netscape 6" or "Opera 5")
{
     echo(
"do this");
     exit();
}
else
{
     echo(
"do this");
     exit();
}
?>
Are those the appropriate values for the user clients; should they be something else? Thanks.
