Common Errors in PHP
If you run a PHP document get the above error message,
'Warning: Cannot modify header information - headers already sent by (output started at filename line no .....) '
it means that an error has occured in your php document. This takes place if there are any executable statements like echo before the set cookie or session variable. Try to find the statement and remove it and then run the same program.
