php - header ("Location: URL); Error -


this question has answer here:

the insert works tested without header redirect. problem i'm using mysqli object oriented approach , still new it. when have header redirect in there tells me in browser

"warning: cannot modify header information - headers sent (output started @ /home/hawkwsco/public_html/admin/include/template/doc.inc.php:1) in /home/hawkwsco/public_html/admin/include/library/functions/process/process.inc.php on line 10"

my code below: 

<?php require ($_server['document_root'].'/admin/include/config/config.inc.php'); $query = ("insert page(pa_id, pa_page, pa_page_info) values ('null', '{$_post['page']}', '{$_post['info']}')"); $mysqli->query($query); header("location: http://".$_server['server_name']."/admin/content.php"); exit; ?>

what doing wrong?

most file including has text in being output (even newline @ end of file enough) causing output start before header can sent. make sure includes not have ?> @ end avoid problem.

alternatively, can use output buffering (ob_start()) avoid output being sent until ready. ob_start() must called before output effective.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
