stdin, stdout

[mazsolt]

I found somewhere that you can write directly on the display if you open the stdout:

$f=fopen("http://stdout","w") or die("problems");
fputs("$f,"hello");

and i got the message:

Warning: fopen(http://stdout) [function.fopen]: failed to create stream: HTTP wrapper does not support writeable connections. in c:\inetpub\wwwroot\hello.php on line 7

I tried the same with stdin:

$f=fopen("http://stdin","r") or die("problems");
$store=fgets("$f,"hello");

Warning: fopen() [function.fopen]: php_network_getaddresses: gethostbyname failed in c:\inetpub\wwwroot\hello.php on line 7

I worked with PHP 4.3 on IIs 5.0

Can anybody tell me how to work with these standard variables?

I am not really sure if I am right here (correct me please if I am wrong). I think you got it all behind your foot ;-) STDIN and STDOUT stands for STAndard IN and STAndard OUT and is the interface in with you communicate with a OS, API or programming language. Like in Perl what you write at the prompt on your *NIX system. I don´t think you could use it at all as you do above. If you start using PHP GTK then you maybe will be able to use STDIN/OUT.
