xmlrpc_decode — 将 XML 译码为 PHP 本身的类型
此函数是实验性的。此函数的表象，包括名称及其相关文档都可能在未来的 PHP 发布版本中未通知就被修改。使用本函数风险自担 。
xmlXML response returned by XMLRPC method.
encodingInput encoding supported by iconv.
Returns either an array, or an integer, or a string, or a boolean according to the response returned by the XMLRPC method.
See example by xmlrpc_encode_request().
Note that from libxml 2.7.9+ there is a limit of 10MB for the XML-RPC response.
If the response is larger, xmlrpc_decode will simply return NULL.
There is currently no way to override this limit like we can with the other xml functions (LIBXML_PARSEHUGE)
Apparently there is a slight problem with xmlrpc_decode (or php) which re-formats this input: <value><double>0.000000</double></value>
As the double number 0.
To get around it, use: number_format($val, 2);
Output would be 0.00
Make sure the server isn't returning a string with a space for the first character, this fails in version 5.3.3 and the function returns null (though seems to be ok in 5.2).
Easily sorted by trimming the response data:
<?php xmlrpc_decode( trim($response) ); ?>
64 bit (i8) integers are not parsed by xmlrpc_decode().
Use a string replacement to work around this:
<?php
$xml = str_replace('i8>', 'i4>', $xml);
$decoded_xml = xmlrpc_decode($xml);
?>
Be careful with encodings, the xmlrpc-decode function is rather strict. For example, the following response parse returns NULL :
<?xml version="1.0"?>
<methodResponse>
<params>
<param>
<value><string>a & b</string></value>
</param>
</params>
</methodResponse>
You should use entities :
<?xml version="1.0"?>
<methodResponse>
<params>
<param>
<value><string>a & b</string></value>
</param>
</params>
</methodResponse>
If your server does not encode responses properly, you may have to process responses before parse.
Use this with an XML-RPC client to decode a server response into native PHP variables. It will automatically translate the response XML-RPC data types into their PHP equivalents.
This function will return only false is there is any problem with format of the XML it receives.
The HTTP response header will need to be stripped off with something like;
<?php
$xml=(substr($response, strpos($response, "\r\n\r\n")+4));
$phpvars = xmlrpc_decode ($xml);
?>
