生成如下XML串
<?xml version="1.0" encoding="utf-8"?> <article> <item> <title size="1">title1</title> <content>content1</content> <pubdate>2009-10-11</pubdate> </item> <item> <title size="1">title2</title> <content>content2</content> <pubdate>2009-11-11</pubdate> </item> </article> 方法I.【直接生成字符串】 1 <?PHP 2 $data_array = array( 3 array( 4 'title' => 'title1', 5 'content' => 'content1', 6 'pubdate' => '2009-10-11', 7 ), 8 array( 9 'title' => 'title2', 10 'content' => 'content2', 11 'pubdate' => '2009-11-11', 12 ) 13 ); 14 $title_size = 1; 15 $xml = "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"; 16 $xml .= "<article>\n"; 17 foreach ($data_array as $data) { 18 $xml .= create_item($data['title'], $title_size, $data['content'], $data['pubdate']); 19 } 20 $xml .= "</article>\n"; 21 header("Content-type: text/xml"); 22 echo $xml; 23 // 创建XML单项 24 function create_item($title_data, $title_size, $content_data, $pubdate_data) 25 { 26 $item = "<item>\n"; 27 $item .= "<title size=\"" . $title_size .
