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";
}
?>`

O exemplo acima irá imprimir algo similar à:

    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 }
