SplFileObject::__construct example

This example opens the current file and iterates over its contents line by line.

<?php
$file = new SplFileObject(__FILE__);
foreach ($file as $line_num => $line) {
    echo "Line $line_num is $line";
}
?>

The above example will output something similar to:

Line 0 is <?php
Line 1 is $file = new SplFileObject(__FILE__);
Line 2 is foreach ($file as $line_num => $line) {
Line 3 is     echo "Line $line_num is $line";
Line 4 is }
Line 5 is ?>
