PHP Session File Hacks
What they say about kung-fu is true..
It can be attained by anyone through hard work over time. You can become as good as the amount of work you put in. Here's a short look at a basic technique that I use. Simply reverse engineering the source code and taking notes along the way...
static void php_session_send_cookie(TSRMLS_D) if (SG(headers_sent)) { if (output_start_filename) { php_error_docref(NULL TSRMLS_CC, E_WARNING, "Cannot send session cookie - headers already sent by (output started at %s:%d)", output_start_filename, output_start_lineno); } else { php_error_docref(NULL TSRMLS_CC, E_WARNING, "Cannot send session cookie - headers already sent"); } return; } /* URL encode session_name and id because they might be user supplied */ e_session_name = php_url_encode(PS(session_name), strlen(PS(session_name)), NULL);
