header('HTTP/1.0 404 Not Found'); not doing anything

Question

I have a 404.php file in my site\'s main directory and I was using header(\'Location: 404.php\'); for a while until someone said that you should use heade

Answer 1

i think this will help you

content of .htaccess

ErrorDocument 404 /error.php
ErrorDocument 400 /error.php
ErrorDocument 401 /error.php
ErrorDocument 403 /error.php
ErrorDocument 405 /error.php
ErrorDocument 406 /error.php
ErrorDocument 409 /error.php
ErrorDocument 413 /error.php
ErrorDocument 414 /error.php
ErrorDocument 500 /error.php
ErrorDocument 501 /error.php

error.php and .htaccess should be put in the same directory [in this case]

Answer 2

For PHP >= 5.4 you can use a simpler function like this : http_response_code(404);
PHP Documentation

Answer 3

You could try specifying an HTTP response code using an optional parameter:

header('HTTP/1.0 404 Not Found', true, 404);

Answer 4

Use these codes for 404 not found.

if(strstr($_SERVER['REQUEST_URI'],'index.php')){
  header('HTTP/1.0 404 Not Found');
  readfile('404missing.html');
  exit();
}

Here 404missing.html is your Not found design page. (it can be .html or .php)

Answer 5

Another reason may be if you add any html tag before this redirect. Look carefully, you may left DOCTYPE or any html comment before this line.

Answer 6

After writing

header('HTTP/1.0 404 Not Found');

add one more header for any inexisting page on your site. It works, for sure.

header("Location: http://yoursite/nowhere");
die;
