New Comment:
Since you're explicitly setting the Host, finecars.cc is used for
all requests, resulting in the undesired behavior. Just remove
that entry from the headers array.

Description:
------------
For $host = 'www.finecars.cc', the HTML content is correctly received.
For $host = 'finecars.cc', the initial response is:
HTTP/1.1 301 Moved Permanently
Location: http://www.finecars.cc/
However, after that, PHP does NOT actually retrieve "www.finecars.cc" as defined in the
Location header, but continues to retry the original URL "finecars.cc" until
'max_redirects' is exhausted.
Test script:
---------------
<?php
declare(strict_types=1);
$host = 'finecars.cc';
$headers = array(
'Host' => $host,
'User-Agent' => 'Anamera/2.0',
'Accept-Charset' => 'UTF-8',
'Referer' => ( '0' == $_SERVER['SERVER_PORT_SECURE']
? 'http' : 'https'
)."://{$_SERVER['SERVER_NAME']}{$_SERVER['REQUEST_URI']}",
'Connection' => 'close',
'Origin' => ( '0' == $_SERVER['SERVER_PORT_SECURE']
? 'http' : 'https' )."://{$_SERVER['SERVER_NAME']}",
);
$header_lines = [];
foreach ( $headers as $name => $entry )
$header_lines[] = "{$name}: {$entry}";
$http_options = array(
'http' => array(
'protocol_version' => 1.1,
'timeout' => 30, // float: seconds.
'follow_location' => 1,
'max_redirects' => 5,
'ignore_errors' => true, // fetch content even on failure status codes.
'method' => 'GET',
'header' => $header_lines,
// 'user_agent' => '', // use:
'header'['User-Agent'].
// 'content' => '', // for POST and PUT.
),
);
$http_context = stream_context_create( $http_options );
$file = file_get_contents( "http://{$host}", false,
$http_context );
var_dump( $http_options, $http_response_header );
die( 'Current PHP version: ' . phpversion() );
?>
Expected result:
----------------
0 => string 'HTTP/1.1 301 Moved Permanently' (length=30)
1 => string 'Content-Type: text/html; charset=UTF-8' (length=38)
2 => string 'Location: http://www.finecars.cc/' (length=33)
3 => string 'Connection: close' (length=17)
4 => string 'Content-Length: 146' (length=19)
5 => string 'HTTP/1.1 200 OK' (length=15)
6 => string 'Content-Type: text/html;charset=iso-8859-1' (length=42)
7 => string 'Connection: close' (length=17)
8 => string 'Content-Length: 87608' (length=21)
Actual result:
--------------
0 => string 'HTTP/1.1 301 Moved Permanently' (length=30)
1 => string 'Content-Type: text/html; charset=UTF-8' (length=38)
2 => string 'Location: http://www.finecars.cc/' (length=33)
3 => string 'Connection: close' (length=17)
4 => string 'Content-Length: 146' (length=19)
5 => string 'HTTP/1.1 301 Moved Permanently' (length=30)
6 => string 'Content-Type: text/html; charset=UTF-8' (length=38)
7 => string 'Location: http://www.finecars.cc/' (length=33)
8 => string 'Connection: close' (length=17)
9 => string 'Content-Length: 146' (length=19)
10 => string 'HTTP/1.1 301 Moved Permanently' (length=30)
11 => string 'Content-Type: text/html; charset=UTF-8' (length=38)
12 => string 'Location: http://www.finecars.cc/' (length=33)
13 => string 'Connection: close' (length=17)
14 => string 'Content-Length: 146' (length=19)
etc.
