class just{
function xmlInclude($data){
$xml = simplexml_load_file(dirname(__FILE__).'/jump.xml');
foreach($xml->Keyword->xpath("//*[data='$data']") as $item){
return $item;
}
}
}
$TR = new just;
$cr = $TR->xmlInclude(查询);
print_r($cr);
$cr=(array)$cr;
echo '<br>';
print_r($cr);
写了一个simplexml解析,print_r发现它出来的是simpleXML object不是数组
SimpleXMLElement Object ( [data] => 查询 [page] => Array ( [0] => dbcon.php [1] => select.php [2] => footer.php ) )
Array ( [data] => 查询 [page] => Array ( [0] => dbcon.php [1] => select.php [2] => footer.php ) )
里面的数值怎么提取,百度上的答案都是转换为数组,我也试着这么做了
可是出来后
echo $cr[0].$cr[0][0].$cr[1][0]
都不能获取到数值并提示:
Notice: Undefined offset: 0 in D:\Program files\WEB Edit\phpLight2013\WWW\Core\xml.php on line 23
Notice: Undefined offset: 0 in D:\Program files\WEB Edit\phpLight2013\WWW\Core\xml.php on line 23
请问怎么样才能从simplexml obj里直接取值?像这种数组中还有数组的情况如何取值?$cr = $TR->xmlInclude(查询);
$cr=(array)$cr;
echo $cr['data'];
echo $cr['page'][1];
注意:$cr=(array)$cr; 只是将第一层对象转换成了数组
