Recipe 18.5 Reading from Standard Input
18.5.1 Problem
You want to read from
standard input.
18.5.2 Solution
Use fopen( ) to open
php://stdin:
$fh = fopen('php://stdin','r') or die($php_errormsg);
while($s = fgets($fh,1024)) {
print "You typed: $s";
}
18.5.3 Discussion
Section 20.4 discusses reading data from the
keyboard in a command-line context. Reading data from standard input
isn't very useful in a web context, because
information doesn't arrive via standard input. The
bodies of HTTP POST and file-upload requests are parsed by PHP and
put into special variables. They can't be read on
standard input, as they can in some web server and CGI
implementations.
