PHP function \http_parse_headers() parses HTTP headers into an associative array.
But is there some reverse function? Which parses associative array into HTTP headers?
Cannot find anything :(
(it's for saveing email into textual .eml file)

3No, there isn't. But it's so trivial to create one on your own, don't you think?Mjh– Mjh2017-04-11 07:56:28 +00:00Commented Apr 11, 2017 at 7:56

There isn't a function that turns associative array into text-representation of headers. The reason: this function is extremely trivial to create.
Headers are defined as key: value delimiter is \r\n.
There is another \r\n delimiter between headers and body.
Lets take an example array:
$headers = [
'Content-Length': 50,
'Content-Encoding': 'gzip'
];
The goal: provide a string that represents HTTP headers
function parse_array_to_headers(array $headers)
{
$result = [];
$delimiter = "\r\n";
foreach($headers as $name => $value)
{
$result[] = sprintf("%s: %s", $name, $value);
}
return implode($delimiter, $result);
}
Note: this function will not check the validity of array and it won't return the string with two repetitions of \r\n at the end. This example serves to show how easy it should be to add missing function. Adjust according to your needs. Also, I didn't test this so don't copy paste it! :)
