Session 错误解决两则

session.auto_start = 0=>1

session.cache_limiter = nocache => ''

Warning: Cannot send session cookie - headers already sent by (output)

quote from the amnual page for setcookie():

setcookie() defines a cookie to be sent along with the rest of the 
header information. Cookies must be sent before any other headers are 
sent (this is a restriction of cookies, not PHP). This requires you to 
place calls to this function before any  or  tags.
