How can you create a multidimensional array from data extracted from a .txt file in PHP?

When extracting data from a .txt file in PHP, you can create a multidimensional array by reading the file line by line and splitting each line into an array of values. You can then push these arrays into a parent array to form the multidimensional structure. 

$data = array();

$file = fopen("data.txt", "r");

if ($file) {
    while (($line = fgets($file)) !== false) {
        $values = explode(",", $line);
        $data[] = $values;
    }
    fclose($file);
}

print_r($data);
