• Use some of the file reading functions (e.g. fgets(), fgetc(), fscanf()) and pass in STDIN as the file path (or php://stdin, depending on how new your version of PHP is).

  You can test for the EOF using feof().

  See the reference for command-line programming in PHP on PHP.net for more information.

• ended up figuring it out myself:

  file_get_contents("php://stdin");
