A little hack to get around this bug:

function &safe_add_child(&$sxml, $name, $value) {
  $safe_value = preg_replace('/&(?!\w+;)/', '&', $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");

Hi,

I have the same problem. My config is :
- PHP 5.2
- libxml Version 2.6.16
---------
<?php
$xmlStr = "<?xml version='1.0' encoding='UTF-8'?><root></root>";
$xml = new SimpleXMLElement($xmlStr);
$xml->addChild("foo",utf8_encode("start < > end"));
echo "foo tag added ok";
$xml->addChild("bar",utf8_encode("start & end"));
echo "error on bar tag because of &amp;";
$result = $xml->asXML();
echo "<pre>".htmlentities($result)."</pre>";
?>

In PHP 4.2.2 I have the same issue.
<code>
<?php
        require_once("sms/messageRelay.class.php");
        $doc = domxml_new_doc("1.0");
        $msg = $doc->create_element("message");
        $msg->set_attribute("type", "MT");
        $doc->append_child($msg);
        $auth = $doc->create_element("authentication");
        $str = "abc < d & e > f";
        $auth->set_content($str);
        $msg->append_child($auth);
        
        echo "<pre>";
        echo $doc->dump_mem(true, "UTF-8");     
        echo "</pre>";
?>
</code>
It chokes on the &.
