Нужно писать XML с помощью PHP – как?

Существует полный пример с php.net/XMLWriter для получения точно такого же XML-вывода, как вы опубликовали.

 <?php $writer = new XMLWriter(); $writer->openURI('php://output'); $writer->startDocument('1.0','UTF-8'); $writer->setIndent(4); $writer->startElement('chart'); $writer->writeAttribute('lowerLimit', '0');

Моим любимым способом записи XML-файлов является XMLWriter – http://php.net/xmlwriter . Это очень мощный и простой в использовании.

$writer->startElement('items'); $writer->startElement("main"); $writer->writeElement('user_id', 3); $writer->writeElement('msg_count', 11); $writer->endElement(); $writer->startElement("msg"); $writer->writeAttribute('category', 'test'); $writer->endElement(); $writer->endElement(); $writer->endDocument(); $writer->flush(); ?> - <?php $writer = new XMLWriter(); $writer->openURI('php://output'); $writer->startDocument('1.0','UTF-8'); $writer->setIndent(4); $writer->startElement('items'); $writer->startElement("main"); $writer->writeElement('user_id', 3); $writer->writeElement('msg_count', 11); $writer->endElement(); $writer->startElement("msg"); $writer->writeAttribute('category', 'test'); $writer->endElement(); $writer->endElement(); $writer->endDocument(); $writer->flush(); ?> - <?php $writer = new XMLWriter(); $writer->openURI('php://output'); $writer->startDocument('1.0','UTF-8'); $writer->setIndent(4); $writer->startElement('items'); $writer->startElement("main"); $writer->writeElement('user_id', 3); $writer->writeElement('msg_count', 11); $writer->endElement(); $writer->startElement("msg"); $writer->writeAttribute('category', 'test'); $writer->endElement(); $writer->endElement(); $writer->endDocument(); $writer->flush(); ?> 

И эта часть кода создаст следующий XML:

 <?xml version="1.0" encoding="UTF-8"?> <items> <main> <user_id>3</user_id> <msg_count>11</msg_count> </main> <msg category="test"/> </items>

Лично я предпочитаю DOM для работы с XML.

Возможно, вы захотите уточнить свой вопрос. Сейчас трудно сказать, в чем проблема.

SimpleXML, встроенный в PHP, является самым простым решением для написания (и анализа) XML. http://php.net/manual/en/book.simplexml.php

С FluidXML вы можете создать свой XML таким образом.

 $chart = fluidxml('chart'); $chart->attr('lowerLimit', 0) ->attr('upperLimit', 100) ->attr(...) ->add('colorRange') ->add('value', 78.9) ->add('target', 80) ->query('//colorRange') ->add('color', ['minValue' => 0, 'maxValue' => 50, ...]) ->add('color', ['minValue' => 50, 'maxValue' => 75, ...]) ->add('color', ['minValue' => 75, 'maxValue' => 100, ...]);

Как упоминалось ранее, setIndent устанавливает отступы и должен использоваться следующим образом:

 $writer->setIndent(true); 

если вы хотите установить размер отступов на другой, чем по умолчанию (2 пробела), вы можете использовать setIndentString:

 $writer->setIndentString(" ");
