[請益] inner child 問題
如題目
有段程式碼，是麻煩同學幫忙寫的，
但是看不太懂，
他最近有點忙，
所以來這邊請教一下各位，
<?
include 'db.php';
header('Content-type: text/xml');
mysql_query("SET NAMES 'utf8'");
$us = mysql_query("select * from runtracker ORDER BY score asc", $con);
//$rows_num = mysql_num_rows($us);
// create a new XML document
$doc = new DomDocument('1.0', 'UTF-8');
// add root node
$root = $doc->createElement('child_item');
$root = $doc->appendChild($root);
while($data=mysql_fetch_row($us))
{
$inner = $doc->createElement('item');
$inner = $root->appendChild($inner);
// add a child node for each field
$child = $doc->createElement('id');
$child = $inner->appendChild($child);
$value = $doc->createTextNode("$data[0]");
$value = $child->appendChild($value);
$child = $doc->createElement('name');
$child = $inner->appendChild($child);
$value = $doc->createTextNode("$data[1]");
$value = $child->appendChild($value);
$d = round((double) $data[2],4);
$child = $doc->createElement('score');
$child = $inner->appendChild($child);
$value = $doc->createTextNode("$d");
$value = $child->appendChild($value);
$child = $doc->createElement('rdate');
$child = $inner->appendChild($child);
$value = $doc->createTextNode("$data[3]");
$value = $child->appendChild($value);
$child = $doc->createElement('rankid');
$child = $inner->appendChild($child);
$value = $doc->createTextNode("$data[4]");
$value = $child->appendChild($value);
}
$xml_string = $doc->saveXML();
echo $xml_string;
mysql_close($con);
?>
db.php 是創建資料庫而已，
麻煩各位了!!
