 New Comment:

I can also reproduce this bug with an XML document:

<?php
$dom = new \DOMDocument();
$dom->loadXML('<root><node/></root>');
$node = $dom->getElementsByTagName('node')->item(0);
echo $dom->saveXML($node, LIBXML_NOEMPTYTAG);

Expected result: <node></node>

Actual result: <node/>

LIBXML_NOEMPTYTAG only applies to XML documents. Yours is HTML.

Use ->saveHTML().

Description:
------------
When executing a PHP script using the Apache module, the DOMDocument::saveXML() LIBXML_NOEMPTYTAG
option is ignored - a self-closing tag, e.g. <body /> is created.

When executing the same script on the commandline, the LIBXML_NOEMPTYTAG option is honored.

This could be a bug in how PHP, Apache and LibXML are compiled by FreeBSD ports, rather than a bug
in PHP itself.

Test script:
---------------
<?php
$dom = new \DOMDocument();
$dom->loadHTML('<body></body>');
$node = $dom->getElementsByTagName('body')->item(0);
echo $dom->saveXML($node, LIBXML_NOEMPTYTAG);


Expected result:
----------------
<body></body>

Actual result:
--------------
<body/>
