What is a request from a different computer?


It is possible that three or more computers need to read the contents in the txt file at the same time, and the ip addresses read by different computers are the same.

Are the ip addresses read by different computers the same? So you want computer a to read 1 Computer B to read 2 computer c to read 3?
Go to the database.

$num = 0;
if(file_exists('count.txt')) $num = file_get_contents('count.txt');
$ar = file('ip.txt');
echo $ar[$num++];
file_put_contents('count.txt', $num, LOCK_EX);
