Reading line by line from STDIN
You could also use a generator - if you don't know how large the STDIN is going to be.
Requires PHP 5 >= 5.5.0, PHP 7
Something along the lines of:
function stdin_stream(){ while ($line = fgets(STDIN)) { yield $line; }}foreach (stdin_stream() as $line) { // do something with the contents coming in from STDIN}
