I have similar problem:

I am using php 4.0.1 pl 2, and redhat 2.2.16 with mysql 3.23.xx.  My problem is that I am losing some values when I set cookie using array.  for example: 

in file: 
loginAction.php

setcookie ("s_cookie[0]","0",time()+3600,"/");
setcookie ("s_cookie[1]","1",time()+3600,"/");
setcookie ("s_cookie[2]","2",time()+3600,"/");
setcookie ("s_cookie[7]","7",time()+3600,"/");

in file:
nSessionAction.php

setcookie ("s_cookie[3]","3",time()+3600,"/");
setcookie ("s_cookie[4]","4",time()+3600,"/");
setcookie ("s_cookie[5]","5",time()+3600,"/");
setcookie ("s_cookie[6]","6",time()+3600,"/");

updateUserSession($s_cook);

in file:
functions.php

function updateUserSession($s_cook){
  for($index=0;$index< count($s_cook);$index++){
    echo $s_cook[$index] . "x";
  }
}


The output I get is as follows:

run #1:
0x1x2xx4xxxx

run #2:
0x1x2x3xxxxx

run #3:
0x1x2xxxxx0x

output changes randomly, though the order of loosing is similar after shutting down the browser and starting it again.  This happens on both Netscape 4.74 and IE 5.0.

in IE5 for mac, I can see the cookies are in right order and have right values.


I have followed the example in php professional programming.
