Turned I had some Empty lines or spaces in my code, >after I removed these empty lines, all was fine. Well, blank space is ok, but it depends on where it is. For example.. ----------- start file1.php3 ----------- <?php SetCookie("TestCookie", "abc"); echo "hi!"; ?> ----------- end file1.php3 ----------- and.. ----------- start file2.php3 ----------- <?php SetCookie("TestCookie", "abc"); echo "hi!"; ?> ----------- end file2.php3 ----------- Which one will work and which will die?? file2.php3 will work and file1.php3 will die. This is because in file1.php3, the whitespace is before the <?php tag. If you want to set a cookie, you cannot have any (or at least a \n) whitespace before the first opening php tag. The second works fine because the <?php tag is the very first thing. The whitespace in that is not sent to the browser, and therefore the script works fine. | |||||
