SplFileObject::current — Retrieve current line of file
Retrieves the current line of the file.
此函数没有参数。
Retrieves the current line of the file. If the SplFileObject::READ_CSV flag is set, this method returns an array containing the current line parsed as CSV data.
If the end of the file is reached, false is returned.
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: }
6: ?>
