#37095 [NEW]: cookie returns random value

From: giaym at hotmail dot com Operating system: Windows 2000 PHP version: 5.1.2 PHP Bug Type: Session related Bug description: cookie returns random value Description: ------------ Randomly, the cookies send back random values to the server, values different than those set the previous page load. I use session auto start on php.ini. PHP runs on Apache 2. Reproduce code: --------------- a, b, locka and lockb are cookies set with setcookie(<name>, <value>, 0, "/"); if($somevar == "lock") { echo "lock"; Set cookies locka and lockb with the values of cookies a and b respectively. } else if($somevar == "random") { echo "random"; Delete locka and lockb, and give a random value to a. } else { echo "none"; if(locka not set) Set random value to a. } if (b not set) Set random value to b. Enter pages in that order: www.domain.com/page/ www.domain.com/page/lock/ www.domain.com/page/random/ www.domain.com/page/lock/ (The if logic works, this is not a case of $somevar holding an incorrect value.) Expected result: ---------------- www.domain.com/page/ received cookies: none output: none sent cookies: a with value x; b with value y www.domain.com/page/lock/ received cookies: a with value x output: lock sent cookies: lock a = x; lock b = y www.domain.com/page/random/ received cookies: a with value x; b with value y; locka with value x; lockb with value y output: random sent cookies: delete lock a; delete lock b; a = z www.domain.com/page/lock/ received cookies: a with value z; b with value y output: lock sent cookies: lock a = z; lock b = y Actual result: -------------- Everything as expected except the last page load: The cookie received isn't a = z, it is a = q, I mean, another value. The server then sends "lock a = q" following the logic. PHPSESSID is received and reset on every page load. 1.
