PHP抓取txt文件中的最后15行 [英] PHP Grab last 15 lines in txt file

问题描述

感谢您花时间阅读本文，无论内容质量如何，我都会感谢您的每一个回复.:)

Thank you for taking the time to read this and I will appreciate every single response no mater the quality of content. :)

使用 PHP，我试图获取文本文档 (.txt) 的最后 15 行并将该数据存储到 php 变量中.我知道这是可能的，但是当我得到最后 15 行时，是否可以保留顺序?例如:

Using PHP, I'm trying to get the last 15 lines of a text document (.txt) and store that data into a php variable. I understand that this is possible, however when I do get the last 15 lines, is it possible to retain the order? For example:

文本文档:

A
B
C

当我从最后 15 个字符中抓取文本文档时，我不希望回声像这样结束:

When I grab the text document from the last 15 characters, I don't want the echo to end up like:

C
B
A

推荐答案

尝试使用 array_slice，它将返回数组的一部分.在这种情况下，您希望它返回数组的最后 15 行，因此:

Try using array_slice, which will return a part of an array. In this case you want it to return the last 15 lines of the array, so:

$filearray = file("filename");
$lastfifteenlines = array_slice($filearray,-15);
