Hi there, I have a simple question to ask: Say i have a PHP script: <?php var_dump($undeclaredVariable); /* The output is NULL */ if($a==$b) { if($c == $d) { $undeclaredVariable = TRUE; } else { $undeclaredVariable = FALSE; } } if($undeclaredVariable == TRUE) { echo 'the undeclared variable is TRUE'; } if($undeclaredVariable == FALSE) { echo 'the undeclared variable is FALSE'; } ?> Reading the PHP Type Comparison Table: $x = null; boolean if($x) = FALSE Using the code above, I see the "the undeclared variable is FALSE", which is OK since it proves the PHP documentation. But as you can see, if $a !=$b then the $undeclaredVarable will not be declared(defined). Is this an "OK" way to work this out? Or should I find a way to declare the variable whatever the case? Thanks in advance, Christos

Thank you both for the answers! It turns out that mac_gyver was right. My previous project was on a VPS server, so all i had to do was to only create a php,ini in the root directory. I followed the same philosophy here and that was problem. So lesson learned: On a shared web server i have to copy php.ini on all folders under root -not only root-. Thanks for the link too.

Hi there, I have an issue that drives me nuts for some days now. I used php.ini to store the sessions to a folder outside root directory: session.save_path = "/home/castos/SESSIONS" As long as the file i call is in the public_html directory (root), session data are OK. If for any reason i use AJAX to call data from a sub-directory (lets say public_html/ajax/test.php), then SESSION data are no longer there (but the session_id is still the same). If i move the same file inside root (public_html/test.php) and call it using AJAX then it works just fine. I feel that the problem could be inside the configuration of the SESSION in php.ini so i am posting the rest of the session configuration: session.save_handler = files session.use_cookies = 1 session.use_only_cookies = 1 session.name = CUSTSESSID session.cookie_httponly = 1 session.cookie_secure = 1 session.hash_function = sha512 session.hash_bits_per_character = 5 session.auto_start = 0 session.cookie_lifetime = 0 session.cookie_path = "/" session.cookie_domain = session.serialize_handler = php session.gc_probability = 1 session.gc_divisor = 100 session.gc_maxlifetime = 1440; session.referer_check = session.entropy_length = 256 session.entropy_file = "/dev/urandom" session.cache_limiter = nocache session.cache_expire = 180 session.use_trans_sid = 0 Any help will be much appreciated! Thanks!
