PHP标头位置不起作用/没有HTTP状态：更改

Question

I'm facing a problem using Headers in PHP. header('location: http:google.com'); is not working. This is my code:

if(!headers_sent()){
    header("location: http://google.com");
    exit;
}

HTML Data...

Script is exiting but header() is not working.

• I've already checked in my php.ini for output_buffer param and it's set to 4096.
• There are not extra lines above PHP opening tag
• and my script is encoding in UTF-8 w/o BOM.
• All errors are enabled but I'm getting no errors/warnings/notices. What is happening?
• Environment: PHP 7.0.27 and NGINX.

Later attempts and debugging steps concluded:

• header("location: http://google.com";, true, 302); made no difference
• header("Refresh: ...") did succeed.

• HTTP response debugging (after being asked a couple of times):

  StatusCode : 200 
  StatusDescription : OK 
  Content : <br />  <b>Notice</b>: Undefined index: HTTP_ACCEPT_LANGUAGE in ...
  RawContent : HTTP/1.1 200 OK 
  Transfer-Encoding: chunked 
  Connection: keep-alive 
  Pragma: no-cache 
  Cache-Control: no-store, no-cache, must-revalidate 
  Content-Type: text/html; charset=UTF-8 
  Date: Fri, 18 May 201... 
  Forms : {} 
  Headers : {[Transfer-Encoding, chunked], [Connection, keep-alive],
  

Unanswered still:

• header("Status: 303 etc"); vs. header('HTTP/1.1 301 Moved Permanently'); from the duplicate

• State of cgi.rfc2616_headers

• PHP SAPI

• Running the sample code outside the phar.

Try this.

     header("Refresh: $seconds; URL=\"$location\"");
