I'm running PHP 5.2.9 on Linux and this bug is still alive and well
making SimpleXml absolutely inappropriate for XML communications between
systems.
<code>
$safe_value = preg_replace('/&(?!\w+;)/', '&amp;', $value);
  return $sxml->addChild($name, $safe_value);
</code>
Is just plain wrong. I'm communicating user input directly to a bank as
I can't know how the third party will parse their xml.

A little hack to get around this bug:

function &safe_add_child(&$sxml, $name, $value) {
  $safe_value = preg_replace('/&(?!\w+;)/', '&amp;', $value);
  return $sxml->addChild($name, $safe_value);
}

PHP 5.2.4
Looks like the problem appears when there's node already exists being
overwritten

// works ok, doesn't require encoding:
$a = simplexml_load_string('<a/>'); 
$a->b = "& < ' ";

// doesn't work, requires encoding:
$a = simplexml_load_string('<a><b>test</b></a>'); 
$a->b = "& < ' "; 

// doesn't work, always requires encoding
$a->addChild('b', "& < '");
$a->addAttribute('b', "& < '");

// works ok, never requires encoding
$a['b'] = "& < '";

I tried the workaround below and it seems to work:

$xml->addChild('element', '');
$xml->element = str_replace("&", "&amp;", "value of the element");
