Encapsulating and reading into an array from text file

Question

I'm trying to make 2 classes, to encapsulate these text files, Customer.txt and Orders.txt. The customer one I need to read each line into a separate instance of an array for each line of text, how can I do this? Also, do I have to do something about the comma's in the text files?

I know I need to use fopen, just not sure how to go about doing it.

This is what I've tried so far.

<?php



class readOrders{

$array_of_lines = fopen("orders.txt", 'r') or die("Failed to create file");
  foreach($array_of_lines as $line) {
 $pieces_of_line = explode(',', $line); 

}

class readCustomers{
$array_of_more_lines = fopen("customers.txt", 'r') or die("Failed to create file");
  foreach($array_of_more_lines as $line) {
 $pieces_of_line = explode(',', $line);

}


?>

Here are my text files

Orders.txt

1,4,0133360903,Building Java Programs,Computer Science
2,6,0321836995,Mathematics All Around,Mathematics
3,24,0321825721,Mathematics for Elementary Teachers with Activity Manual,Mathematics
4,10,0133011208,Business Math,Business

customers.txt

I think fgetcsv will be useful here, example from php-doc:

<?php
$row = 1;
if (($handle = fopen("test.csv", "r")) !== FALSE) {
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
        $num = count($data);
        echo "<p> $num fields in line $row: <br /></p>\n";
        $row++;
        for ($c=0; $c < $num; $c++) {
            echo $data[$c] . "<br />\n";
        }
    }
    fclose($handle);
}
?>
