Bug description:get_headers and $http_response_header returns unusable
formatting
Description:
------------
The get_headers() function and the $http_response_header variable often
returns multiple headers combined into a completely unusable format.
Test script:
---------------
<pre>
<?php
/*
The get_headers() function and the $http_response_header variable often
returns
multiple headers combined into a completely unusable format.
*/
echo "Testing the \$http_response_header format\n";
file_get_contents('http://google.com/');
print_r($http_response_header);
echo "Testing the normal get_headers format\n";
$headers=get_headers('http://google.com/');
print_r($headers);
echo "Testing the get_headers format with keys\n";
$headers=get_headers('http://google.com/',1);
print_r($headers);
?>
Expected result:
----------------
Each set of headers from each request should be separated into another
array, rather than simply appended to the existing ones.
There is currently no safe way to separate the returned values into a
usable format. The get_headers format with keys is the worst offender of
this.
Actual result:
--------------
