redirect a file contents to standard input in php

Question

I have a file abc.txt with contents like:

hello
hi
good
bad
...
....

Now, How to redirect the contents of the file line by line to a php script's standard input, so that when the php script is executed, it can collect the inputs by any of these commands:

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

or

$f = fgets(STDIN);

Answer 1

php yourscript.php < yourinputfile

should do the trick.
