인수

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.

반환값

Returns an object of class SimpleXMLElement with properties containing the data held within the xml document,실패 시 FALSE를 반환합니다.

Warning

이 함수는 논리 FALSE를 반환하지만, 논리 FALSE로 취급할 수 있는 다른 값을 반환할 수 있습니다. 자세한 정보는 논리형 섹션을 참고하십시오. 이 함수의 반환값을 확인하려면 === 연산자를 이용하십시오.

오류/예외

Produces an E_WARNING error message for each error found in the XML data.

Tip

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);
?>

위 예제의 출력:

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.
