Print a line from file to .php file.

Hi.

I have a file with unique information on each line, I want one line at a time to be printed to file.php with a 20min interval.

ex info file.
"abc
def
ghi
jkl
mno"

So, for the first 20min i want "abc" to show in file.php, after 20min it should show "def" and after another 20min i want it to show "ghi", and so on..
It doesnt matter if it reads from the info file or if I paste the contents to file.php and it reads from within itself, so to speak.
Im sure this could be easily done, right?

Anyone care to help out? I would be very greatful!

 

If I understand correctly, You need some thing like this:

file.php

<?php

    $file = 'some.info'; // info-file
    $delay = 20*60; // Delay in seconds
    
    $info = file($file);
    $count = count($info);
    
    $key = time() % ($delay*$count);    
    print trim($info[(int)$key/$delay]);    

?>

PHP:
