writing to a text file in php

Say I wanted to add the string $ip to the text file ip.txt in the same directory. I am currently using file_get_contents to read from the text file.

Answer 1

You could use file_put_contents

<?php
  $ip = "foo";
  file_put_contents("ip.txt", $ip, FILE_APPEND);
?>

FILE_APPEND will append the text. Absence of this flag will cause file-overwriting.
