simplexml_load_string — Interprets a string of XML into an object

说明

object simplexml_load_string ( string $data [, string $class_name [, int $options [, string $ns [, bool $is_prefix ]]]] )

Takes a well-formed XML string and returns it as an object.

参数

A well-formed XML string

class_name

You may use this optional parameter so that simplexml_load_string() will return an object of the specified class. That class should extend the SimpleXMLElement class.

options

Since PHP 5.1.0 and Libxml 2.6.0, you may also use the options parameter to specify additional Libxml parameters.

ns

is_prefix

返回值

Returns an object of class SimpleXMLElement with properties containing the data held within the xml document. On errors, it will return FALSE.

范例

Example#1 Interpret an XML string

<?php
$string 
= <<<XML
<?xml version='1.0'?> 
<document>
 <title>Forty What?</title>
 <from>Joe</from>
 <to>Jane</to>
 <body>
  I know that's the answer -- but what's the question?
 </body>
</document>
XML;

$xml simplexml_load_string($string);

var_dump($xml);
?>

上例将输出:

SimpleXMLElement Object
(
  [title] => Forty What?
  [from] => Joe
  [to] => Jane
  [body] =>
   I know that's the answer -- but what's the question?
)

At this point, you can go about using $xml->body and such.
