Cannot send session cache limiter – headers already sent Error in php Session

Well, Session have both plus and minus parts, but we do use them largely in PHP. So, while developing have you come across Cannot send session cache limiter – headers already sent error but you can’t find any echoed part on the given file? I have got this problem and found out that there is a left over space at the end of the file.
So check if you have spaces either at the beginning or at the end of your file and remove that.
