    示例 #1 SplFileObject::current() example

    <?php
    $file     = new SplFileObject(__FILE__);
    foreach (    $file as $k => $line) {
    echo (    $file->key() + 1) . ': ' . $file->current();
    }
    ?>

    以上示例的输出类似于：

    1: <?php 2: $file = new SplFileObject(__FILE__); 3: foreach ($file as $line) { 4: echo ($file->key() + 1) . ': ' . $file->current(); 5: } 6: ?>
