SimpleXMLElement::attributes — Identifies an element's attributes
$namespaceOrPrefix = null, bool $isPrefix = false): ?SimpleXMLElementThis function provides the attributes and values defined within an xml tag.
注意: SimpleXML 建起了一個(gè)給大多數方法添加迭代屬性的規則。不能通過(guò)使用 var_dump() 或任何可檢查對象的其它東西來(lái)查看。
namespaceOrPrefixAn optional namespace for the retrieved attributes
isPrefix
Default to false
Returns a SimpleXMLElement object that can be iterated over to loop through the attributes on the tag.
Returns null if called on a SimpleXMLElement
object that already represents an attribute and not a tag.
示例 #1 Interpret an XML string
<?php
$string = <<<XML
<a>
<foo name="one" game="lonely">1</foo>
</a>
XML;
$xml = simplexml_load_string($string);
foreach($xml->foo[0]->attributes() as $a => $b) {
echo $a,'="',$b,"\"\n";
}
?>
以上例程會(huì )輸出：
name="one" game="lonely"
