  • What is `STDIN`? a string, a constant? – Sean May 16 '15 at 05:32

    Are you running that in a web mode? [STDIN](http://php.net/manual/en/features.commandline.io-streams.php) is a CLI specific constant. – Ulver May 16 '15 at 05:42
  • I think u should use define('STDIN',fopen("php://stdin","r")); in the at top of the php file. – user3419778 May 16 '15 at 06:17

Assuming you are running from command line interface (CLI):

Define a STDIN constant at the top of your file:

define('STDIN', fopen('php://stdin', 'r'));

Or just replace STDIN constant with:

$name = trim(fgets(fopen('php://stdin', 'r')));

$stdin = fopen('php://stdin', 'r');

$name=trim(fgets($stdin));

echo "\nThanks, " . $name . ", it's really nice to meet you.\n\n";

fclose($file);
