Description:

From manual page: http://www.php.net/function.http-build-query
---
The php.ini file says:

; The separator used in PHP generated URLs to separate arguments.
; PHP's default setting is "&".
; http://php.net/arg-separator.output
; Example:
;arg_separator.output = "&"

So "&" should the default setting, but the result of http_build_query() is with "&".


$data = array(
	'secret'	=> 'value_secret',
	'response'	=> 'value_response',
);

echo http_build_query($data) ."\n";
Results into "secret=value_secret&response=value_response"

echo http_build_query($data, null, '&') ."\n";
Results into "secret=value_secret&response=value_response".


Also the phpinfo() function output for "arg_separator.output" is "&" but is displayed in the generated HTML-Page as simple "&" which is confusing.

This is also at the default php.ini settings at "arg_separator.input".


--------

If i set "arg_separator.output" to "&" or '&' in the php.ini, then i also get "&" with http_build_query().

ini_get('arg_separator.output') also returns "&" then.


Test script:
---------------
$data = array(
	'secret'	=> 'value_secret',
	'response'	=> 'value_response',
);
echo ini_get('arg_separator.output') ."\n";
echo http_build_query($data) ."\n";
echo http_build_query($data, null, '&') ."\n";
