每隔24小时从文件中读取文本并从行中加载新的字符串

问题描述

经过几个小时的研究，我编写了此脚本:

After some hours of research I made this script:

function get_string_on_interval($strings, $interval) {
    return $strings[round((time()/$interval - floor(time()/$interval)) * sizeof($strings))];
}

echo get_string_on_interval(file('matlista.txt'), 60*60*24);

在此matlista.txt中，我在每行/每行上都有一个特定的单词.该脚本显示了我网站上此文本文件中的字符串，但问题是它没有从index 1(它是行/行1)开始显示，而是从line 46开始.我不知道自己在做什么错，但我希望此脚本从line 1中读取，并且在24小时后应转到line 2，依此类推，并每24小时显示不同的行.该脚本开始显示line 46并从那里继续，我找不到问题.

In this matlista.txt I have a specific word on each row/line. This script shows a string from this text file on my site but the problem is that it doesn't start showing from index 1 (which is row/line 1) it starts from the line 46. I don't know what I'm doing wrong but I want this script to read from line 1 and after 24 hours it should go to line 2 and so on and display the different lines every 24 hour. This script starts to show line 46 and continues from there, I can't find the problem.

推荐答案

$data = array(
'line1',
'line2',
'line3'
);

function get_string_on_interval($strings, $interval)
{
   $startTime = '2014-03-11 18:14:00';
   return $strings[floor((time() - strtotime($startTime)) / $interval) 
                % count($strings)]; 
}

echo get_string_on_interval($data, 10);

$startTime是您要计数"行的日期时间(显示第一行时).示例应每10秒更改一次行.

And $startTime is the datetime from which you want to 'count' the lines (when the first line is shown). Example should change the line every 10 seconds.
