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.

Answer 2

file_put_contents() with FILE_APPEND flag appends text to given file:

file_put_contents('filename.txt', $stringToAppend, FILE_APPEND);
