headers_sent() return false, but headers were sent
html, http-headers, php
Solution
It depends if your `output_buffering` directive in `php.ini` file. If it is `Off`
`output_buffering = Off`
then `echo headers_sent()` should output `1`
In other cases, `headers_sent()` won't output any results because it will be FALSE. The headers won't be sent because the output is buffered.
If you want to get around this and force-send headers, you can use `flush()`.
Hope this helps!
Problem
My code is simple: ``` <!DOCTYPE html> <html> <head> ... <?php var_dump(headers_sent()); ?> ``` It returns false. Shouldn't the headers be sent immediately after something is printed? Like just after the first `<` character.
