For a completely valid XHTML document you have to set the arg_separator, use this before you use output-add-rewrite-var:
<?php
ini_set('arg_separator.input', '&');
ini_set('arg_separator.output', '&');
?>
(PHP 4 >= 4.3.0, PHP 5, PHP 7, PHP 8)
output_add_rewrite_var — Add URL rewriter values
This function starts the 'URL-Rewriter' output buffer handler
if it is not active,
stores the name and value parameters,
and when the buffer is flushed rewrites the URLs
and forms based on the applicable ini settings.
Subsequent calls to this function will store all additional name/value pairs
until the handler is turned off.
When the output buffer is flushed
(by calling ob_flush(), ob_end_flush(),
ob_get_flush() or at the end of the script)
the 'URL-Rewriter' handler adds the name/value pairs
as query parameters to URLs in attributes of HTML tags
and adds hidden fields to forms based on the values of the
url_rewriter.tags and
url_rewriter.hosts
configuration directives.
Each name/value pair added to the 'URL-Rewriter' handler
is added to the URLs and/or forms
even if this results in duplicate URL query parameters
or elements with the same name attributes.
Зауваження: Once the
'URL-Rewriter'handler has been turned off it cannot be started again.

| 7.1.0 | As of PHP 7.1.0, a dedicated output buffer is used, url_rewriter.tags is used solely for output functions and url_rewriter.hosts is available. Prior to PHP 7.1.0, rewrite variables set by output_add_rewrite_var() shared an output buffer with transparent session id support (see session.trans_sid_tags). |

For a completely valid XHTML document you have to set the arg_separator, use this before you use output-add-rewrite-var:
<?php
ini_set('arg_separator.input', '&');
ini_set('arg_separator.output', '&');
?>This function also adds a parameter to <input type="image"> fields!
Example:
This code:
<?
output_add_rewrite_var ('var','value');
echo '<form action="" method="post">
<input type="image" src="image.jpg" alt="go">
</form>';
?>
will output something like this:
<form action="" method="post">
<input type="hidden" name="var" value="value">
<input type="image" src="image.jpg?var=value" alt="go">
</form>
