Help with setcookie function

[zlatangu]

I have a problem, each time that i reload the page i get a different $num variable why is that happening? Can somebody help me, i'm beginner in php.

<?php
if(isset($_COOKIE["nums"])){
	$num = $_COOKIE['nums'];
}else{
	$num = rand(1,9).date('Y').date('m').date('d').date('h').date('i').date('s');
	setcookie("nums",$num, 9999999999);  	
}  
  echo "You have  " .$num. "  ....";
?>

The code seems to work for me. Do you have cookies disabled?

 

Note that the code could be simplified a bit by calling date() once.

$num = rand(1,9).date('Ymdhis');

The thing I noticed is your expiration time. It's a unix timestamp. If I enter

echo date('Y-m-d H:i:s', 9999999999);

I get 2014-09-06 21:50:07

 

So it means the cookie is already expired.

are you getting a header error due to outputting something (or even your file having been saved with a byte order mark character) before the setcookie() statement?

 

having php's error_reporting/display_errors set to report and display all php errors, when debugging code problems, will help.

Hmm...for some reason, I get "2286-11-20 09:46:39".

 

@zlatangu - The documentation for setcookie() recommends that you use the time() function when setting the expiration date. Here is an example provided in the manual:

<?php
$value = 'something from somewhere';
setcookie("TestCookie", $value, time()+3600);  /* expire in 1 hour */
?>
