Read a text file line by line and split text

[ashking]

Hi I am quite new to php programming but I have started a new personal project which I need a bit of help/advice on it please.

This piece of code randomly picks a line within the file:
rand.php

<?php
$filename = 'file.pwf'; 
$how_many_to_show = 1; 
if ($fileContents = file($filename)) { 
 shuffle($fileContents); 
 for ($i = 0; $i < $how_many_to_show; $i++) { 
$myvariable = ($fileContents[$i]);
echo $myvariable;
 }
} else { 
 die('Could not get contents of: ' . $filename); 
}  
?>

This is an example of what the 'file.pwf' file looks like:

file.pwf

qshidfe:fh2ue24
fijwsdf:fj28fr8b
[e-mail]:848rfuw

I want to be able o store the first part as a variable for the username and the second part as a variable as the password.

Also I need it to work with the rest of the code, how would i link rand.php within index.php using the variables?

index.php

$user = ''; //Has to be the first variable from rand.php
$pass = '';  //Has to be the second variable from rand.php

Any help at all would be highly appreciated. Thankyou
Ash King.
