RE: [PHP] HTTP_USER_AGENT?

I use <? phpinfo(); ?> in both php3 and php4 and it works fine. All the commands that I have used are all forward compatible. I even have some php2 code that still works in php4!

Thanks that worked just fine. But now I am irritated as hell. Obviously there is no backwards compatibility with new releases. Does this mean if I install a new version of PHP then all books published before that date are worthless? Seems so. For example in a book discussing PHP 3 it says: <? phpinfo(); ?> This works just fine. In a book that discusses PHP 4 it says: <? php_info() ?> This gives "Fatal error: Call to undefined function: php_info() in c:\inetpub\wwwroot\php\phpinfo.php on line 2." So it's not just backwards compatibility it is careless planning. This is not good. I will have to search hi and lo to determine if a failure is due to incorrect syntax because of version and not just careless typing on my part. I remember when FORTRAN was being developed we were assurred that all previous commands from older versions would continue operative in the new. FORTRAN 77 to FORTRAN 90. I think the developers of PHP ought to consider why the developers of FORTRAN thought that might be a good thing to do. It is still used to this day. Write a FORTRAN 77 prog and it will compile and run on a FORTRAN 90 compiler out of the box. Thanks again. -- George Hester _________________________________ "Justin French" <justin@indent.com.au> wrote in message news:B9532D6D.A2C5%justin@indent.com.au... > Try: > > <? echo $_SERVER['HTTP_USER_AGENT']; ?> > > ... you might have a newer version of PHP (4.1+), which uses the global > arrays like: > > $_SERVER > $_POST > $_GET > $_SESSION > $_COOKIE > > ... > > > Justin French > > > > > on 11/07/02 12:32 PM, George Hester (hesterloli@hotmail.com) wrote: > > > I have this in my web site not in an executable folder: > > > > <HTML> > > <HEAD> > > <TITLE>My First PHP Program</TITLE> > > </HEAD> > > <BODY> > > <?php echo "Hello World!"; ?> > > </BODY> > > </HTML> > > > > No problem.
