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.

If you have many names (more than 100), it may run slowly. If you have thousands of names, it may run very slowly.

Here's some code to help:

$users = file('path/to/myfile.txt');
$user = array_rand($users);
$user = explode(',',$user,1);
$password = $user[1];
$username = $user[0];
