If you intermix writing sub-elements and attributes, any attempt to write attributes after the first sub-element will fail and return false:
<?php
$xml = new XMLWriter();
$xml->openMemory();
$xml->startElement('element');
$xml->writeAttribute('attr1', '0');
$xml->writeElement('subelem', '0');
var_dump($xml->writeAttribute('attr2', '0'));
$xml->endElement();
echo $xml->flush();
?>
Outputs:
bool(false)
<element attr1="0"><subelem>0</subelem></element>
This is because this is a forward-only writer and the start tags are already finished. There is no going back to add more attributes later, there is no place to put attr2. This is exactly how it is supposed to work.
XMLWriter::writeAttribute
xmlwriter_write_attribute
(PHP 5 >= 5.1.2, PHP 7, PECL xmlwriter >= 0.1.0)
XMLWriter::writeAttribute -- xmlwriter_write_attribute — Write full attribute
설명
객체 기반 형식
bool XMLWriter::writeAttribute
( string
$name
, string $value
)절차식 형식
bool xmlwriter_write_attribute
( resource
$xmlwriter
, string $name
, string $value
)Writes a full attribute.
인수
-
xmlwriter -
순차적 호출에서만 사용. XMLWriter resource가 수정됩니다. 이 자원은 xmlwriter_open_uri()나 xmlwriter_open_memory() 호출로 만들어집니다.
-
name -
The name of the attribute.
-
value -
The value of the attribute.
반환값
성공 시 TRUE를, 실패 시 FALSE를 반환합니다.
참고
- XMLWriter::writeAttributeNS() - Write full namespaced attribute
- XMLWriter::startAttribute() - Create start attribute
- XMLWriter::startAttributeNS() - Create start namespaced attribute
- XMLWriter::endAttribute() - End attribute

If you intermix writing sub-elements and attributes, any attributes that are written after the first sub-element are ignored/discarded:
<?php
$xml->startElement('element');
$xml->writeAttribute('attr1', 0);
$xml->writeElement('subelem', 0);
$xml->writeAttribute('attr2', 0);
$xml->endElement();
?>
Outputs:
<element attr1=0>
<subelem>0</subelem>
</element>
This is stupid, but the way it works as of PHP 5.2.4.
