Recipe 23.4. Reading from Standard Input

Recipe 23.4. Reading from Standard Input 23.4.1. Problem You want to read from standard input in a command-line context'for example, to get user input from the keyboard or data piped to your PHP program. 23.4.2. Solution Use fopen( ) to open php://stdin, as in Example 23-15. Reading from standard input <?php $fh = fopen('php://stdin','r') or die($php_errormsg); while($s = fgets($fh)) { print "You typed: $s"; } ?> 23.4.3. Discussion Recipe 25.3 discusses reading data from the keyboard in a command-line context in more detail. 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. Non-file-upload post request bodies can also be read with the php://input stream, as discussed in Recipe 8.7. 23.4.4. See Also Recipe 25.3 for reading from the keyboard in a command-line context; Recipe 8.7 for reading POST request bodies; documentation on fopen( ) at http://www.php.net/fopen.
