i don't understand you question

be more specific or give a usage exemple

I think what he means is like the user has there account info and they are able to "update" their account info if they want or need... if this is true and are using a database you could use an update query

[abnfire]

i mean i have a file name my.php and my.php content following:

<?php

$db_name = "life"; //database name
$db_user = "abnfire"; // Database username

and more code....
?>

Now i want to change the value of db_name variable using browser, and change of this variable will be forever.

Oh, so you want to write a text file that happens to contain PHP code?

<?php
$new_name = 'life';
$new_user = 'abnfire';
...
$fp=fopen('config_file.php','r');
fwrite($fp,"<?php\n");
fwrite($fp,"\$db_name='$new_name';\n");
fwrite($fp,"\$db_user='$new_user';\n");
...
fwrite($fp,"?>\n");
fclose($fp);
?>
