multi arrays and fetching variables

lets say I have an external text file .txt with the following

A1
A2
B1
B2
C1
C2
..
..
..

And I have multiple php pages. How would I fetch A1 on one page and A2 on another page? And then when you refresh the pages it fetches some other random pair like R1 R2?

Is there a way to do this?

 

Is the same person loading both the two pages where A1 and A2 appear?

 

actually I have a simpler question regarding pairs on one page

this script keeps giving me an error. I'm trying to echo both array values and it wont work

 

<?

$array = array('eggs', 'bacon', 'football', 'baseball', 'ford', 'toyota'); 

$rand_index = mt_rand(0, count($array) / 2 - 1) * 2; 

echo $array[$rand_index] . " <br> " . $array[$rand_index + 1]; 

?>



<?php echo "$array[$rand_index]"; ?><?php echo "$array[$rand_index+1]"; ?>

PHP:

 

The code works fine when I try it, except for this part:

<?php echo "$array[$rand_index+1]"; ?>

PHP:

Addition won't be evaluated like that in a string. Get rid of the double quotes.

<?

$array = array('eggs', 'bacon', 'football', 'baseball', 'ford', 'toyota');

$rand_index = mt_rand(0, count($array) / 2 - 1) * 2;

echo $array[$rand_index] . " <br> " . $array[$rand_index + 1];

?>



<?php echo $array[$rand_index]; ?><?php echo $array[$rand_index+1]; ?>

PHP:

 

off the top of my head: you need a queue table with pairs that can be fetched at a given time along with their fetch status.
