gettings started with reading streams in PHP

getting-started-streams.php

<?php

// Open the stream
$numbers = fopen(__DIR__ . '/numbers.txt', 'r');
// Wrap our parser in an infinite loop, so it won't stop until we say so
while (true) {
	// Read a line
	$buffer = fgets($numbers);
	// The docs say it will return false when there arent any bytes left,
	// so we break out of our loop and let the sript die when that happens.
	if (!$buffer) {
		break;
	}
	// Here you would upload it to the 'system', whatever that is.
	// Lets just echo it to make sure our script works.
	echo $buffer;
}
// Close the stream.  PHP will do this anyway when the script ends,
// but it's good practice to always do it.
fclose($numbers);
