Detect console end of the input in PHP-Cli

Is there any form to detect the end of a console input?

Im using something like this:

<?php
while($consoleInput = fgets(S开发者_运维问答TDIN)) {

 //do something

}
?>

Any sugestions?

How about feof()? Untested, but I believe this will work.

while (!feof(STDIN)) {
  $consoleInput = fgets(STDIN);
}

if (feof(STDIN)) {
   do_something()
};
