Random username and password from CSV file

[young_coder]

Dear all,
Can somebody help me please?
Instead of ‘username’ and 'password', I need random values from CSV file.
Can somebody show me how can I do this?

My CSV file looks like this:

user001,userpass001
user002,userpass002
user003,userpass003

My script looks like this:

<?php
$t= new post();
$t->username='username';
$t->password='password';
$res = $t->update('This is some text.');
?>

Thank you very much advance.

As in you need to use the values read from a file in CSV format, rather than "random values"? If so, look into [man]fgetcsv/man.
