Answer 1

This tutorial should get you going

$myFile = "testFile.txt";
$fh = fopen($myFile, 'a') or die("can't open file");
$stringData = "String 1\n";
fwrite($fh, $stringData);
$stringData = "String 2\n";
fwrite($fh, $stringData);
fclose($fh);

Answer 2

To write to file b.txt (for example) use this:

<?php
$fp = fopen('b.txt', 'a');
fwrite($fp, '1');
fclose($fp);

That will write "1" to b.txt every time you run it.

Answer 3

The easiest is to use the file_put_contents function with the FILE_APPEND flag:

file_put_contents('filename', 'data', FILE_APPEND);
