simplexml_load_string — Interprets a string of XML into an object
说明
SimpleXMLElement simplexml_load_string ( string $data [, string $class_name = "SimpleXMLElement" [, int $options = 0 [, string $ns = "" [, bool $is_prefix = false ]]]] )Takes a well-formed XML string and returns it as an object.
参数
- data
-
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
-
Namespace prefix or URI.
- is_prefix
-
TRUE if ns is a prefix, FALSE if it's a URI; defaults to FALSE.
返回值
Returns an object of class SimpleXMLElement with properties containing the data held within the xml document, 或者在失败时返回 FALSE.
错误/异常
Produces an E_WARNING error message for each error found in the XML data.
TipUse libxml_use_internal_errors() to suppress all XML errors, and libxml_get_errors() to iterate over them afterwards.

<?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?
