(PHP 5, PHP 7)
simplexml_load_string — Interprets a string of XML into an object
$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.
dataA well-formed XML string
class_nameYou 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.
nsNamespace prefix or URI.
is_prefix
TRUE if ns is a prefix, FALSE if it's a URI;
defaults to FALSE.
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.
Produces an E_WARNING error message for each error
found in the XML data.
Use libxml_use_internal_errors() to suppress all XML errors, and libxml_get_errors() to iterate over them afterwards.
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);
print_r($xml);
?>
以上例程会输出：
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.
