示例 #1 SplFileObject::current() example


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

以上例程的输出类似于：

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