I am a bad student == I don’t know how to learn a lot by myself. I want to ask a question from a master. The code in the book is as follows:

<?php

date_default_timezone_set("Etc/GMT-8 ");

if(!isset($_COOKIE["visittime"])){ //If the cookie does not exist

setcookie("visittime",date("y-m-d H:i: s")); //Set a Cookie variable

echo "first time to meet:".date("y-m-d H:i:s")."<br>"; //Output string

}else{ //If Cookie exists

setcookie("visittime",date("y-m-d H:i:s"),time() 60); //Set variables with Cookie expiration time

echo "last time:".$_COOKIE["visittime"]; //Output the time of the last visit to the website----------- --------------

echo "<br>"; //Output carriage return character

}

echo "now : ".date("y-m-d H:i:s"); //Output the current access time *********************

?>

Question: What I want to ask is == created a new cookie file, re-execute this command. Why is the time in setcookie() in the line in the remarks changed to the current time date("y-m-d H:i:s"), and then there is -------- in the remarks? - The line can also output the last time instead of the current time. Then, there is *********** in the remarks but the output is the current time, which is correct== What's going on? What's going on when the line of ------------- arrives? God, please help. T T
