Four ways to generate xml files in php

 title1
 content1
 2009-10-11


 title2</title> ;</li>
<li> <content>content2</content></li>
<li> <pubdate>2009-11-11</pubdate></li>
<li> </item></li>
<li></article></li>
</ol></div>
<em onclick="copycode($('code_CAg'));">Copy code</em>
</div>
<p>Method 1, generate directly string
Use pure PHP code to generate a string and write the string to a file with an XML suffix.

<div class="blockcode">
<div id="code_O2x"><ol>
<li>
<li>
<li><p><?PHP<li>$data_array = array(<li> array(<li> 'title' => 'title1',</li>

<li>function create_item($title_data, $title_size, $content_data, $pubdate_data)</li>
<li>{</li>
<li> $item = "<item>n";</li>
<li> $item .= "< ;title size="" . $title_size . "">" . $title_data . "n";
 $item .= "" . $content_data . "n ";
 $item .= " " . $pubdate_data . "n";
 $item .= "n";
 return $item;
}
?>

Method 2, use DomDocument to generate XML files Steps: 1. Create nodes using the createElement method. 2. Create text content using the createTextNode method, 3. Add child nodes using the appendChild method. 4. Create attributes using the createAttribute method

$data_array = array(
 array(
 'title' => 'title1',
 'content' => 'content1',
 'pubdate' => '2009-10-11',
 ),
 array(
 'title' => 'title2',
 'content' => 'content2',
 'pubdate' => '2009-11 -11',
 )
);
// Attribute array
$attribute_array = array(
 'title' => array(
 'size' => 1
 )
) ;
// Create an XML document and set the XML version and encoding. .
$dom=new DomDocument('1.0', 'utf-8');
// Create root node
$article = $dom->createElement('article');
 $dom->appendchild($article);
foreach ($data_array as $data) {
 $item = $dom->createElement('item');
 $article- >appendchild($item);
 create_item($dom, $item, $data, $attribute_array);
}
echo $dom->saveXML();
function create_item( $dom, $item, $data, $attribute) {
 if (is_array($data)) {
 foreach ($data as $key => $val) {
 // Create element
 $$key = $dom ->createElement($key);
 $item->appendchild($$key);
 // Create element value
 $text = $dom->createTextNode($val );
 $$key->appendchild($text);
 if (isset($attribute[$key])) {
 // If there are related attributes in this field, they need to be set
 foreach ($attribute[$key] as $akey => $row) {
 // Create attribute node
 $$akey = $dom->createAttribute($akey);
 $$key->appendchild($ $akey);
 // Create attribute value node
 $aval = $dom->createTextNode($row);
 $$akey->appendChild($aval);
 }
 } // end if
 }
 } // end if
} // end function
?>
