This should do it.  Obviously change the file name.  This places each pippoxxx on a newline.

<?php
 
	if ($file = fopen ("C:\\file2.txt", "w")) {
		for ($i = 0; $i < 100000; $i++) {
			fwrite ($file, 'pippo' . str_pad($i, 6, '0', STR_PAD_LEFT) . PHP_EOL);
		}
	}
	
?>

Oh, silly me.  Change the 100000 to 1000000.  I used 100000 for testing.
