you DO understand that STDIN is a resource and (unlike Perl,) PHP can't
compare a string to a resource! Next, you're comparing to '\n', note the
single quotes; you're not comparing to the newline char, you're
comparing to a \ followed by an n literally.
So..., your code will spit out errors for sure.
while(($line = fgets(STDIN)) != "\n");
{
echo $line;
}
would work though, and have the same functionality you tried to achieve
in your above code.

it is opened, but you need to use it correctly to get there ;)
