I'm not sure if this would be the best way to do it...
However, the basic functions you'll need to use are PHP's file functions. The simplest way to do it would be...
php Syntax (Toggle Plain Text)
file_get_contents() takes a filename (string) and returns the contents of the file in a string.
file_put_contents takes a filename (string) and contents (string) and writes them to the file.
For storing usernames and passwords, the best solution is probably to use a mysql database. You could read the databases section of Practical PHP Programming for an overview of mysql and the related php functions.
Another option would be to use an xml file to store the usernames and the hashed passwords (after they've been processed with md5 or crypt). This is a simpler option if you don't have access to or don't want to use a database.
PHP has some great built in functionality with xml now using SimpleXML. You could read the SimpleXML section of Practical PHP Programming for an overview on how to use it to read, write, and modify xml data.
Good luck,

Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning.

I solved my problem like this..
changepwd.php
strings.php
changepwd.php
include("strings.php");
$checkpass=$pass;
$newpass=$_REQUEST['NewPwd'];
$fn = "strings.php";
$file = fopen($fn, "w+");
$size = filesize($fn);
fwrite($file, "<?php "."$"."pass='".$newpass."';?>");
fclose($file);
echo "Password changed successfully";strings.php
<?php $pass='venkat';?>

Should be plenty safe. No one will be able to see the password details, because it will be parsed by the php interpreter. Just like how your mySQL user/password information is floating around somewhere in a config.php file...
Are you just saving one password in there? Or are there more users?

Ahh, I thought that you were going to store a bunch (or at least a handful of users).
If you tried to add more records to the file, it would get more complicated to parse the variable names, make sure you didn't use the same name twice, etc.
But for one user, I suppose it's simple enough. Definitely a strange way to do it, but if it works, who cares? Kudos for thinking outside the box.
