php xmlrpc decode bug for large size and solution

1. When the response is large than 10MB the xmlrpc decode will return null

https://www.php.net/manual/en/function.xmlrpc-decode.php

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)


2.  solution parse using the

SimpleXML

example:

<?php

        //Enter your code here, enjoy

    $xmlString = <<<EOF

<?xml version='1.0'?>

<methodResponse>

        <params>

            <param>

                <value>

                    <array>

                        <data>

                            <value>

                                <string>Hello</string>

                            </value>

                            <value>

                                <string>Andy</string>

                            </value>

                        </data>

                    </array>

                </value>

            </param>

        </params>

</methodResponse>

EOF;

$xml = new SimpleXMLElement($xmlString);

if ($xml===null || !is_object($xml))

    die('Failed to load xml file.');

    

echo "ok";    

//print_r($xml);

echo $xml->params->param->value->array->data->value->string;

echo $xml->params->param->value->array->data->value[1]->string;

php unicode to utf8

<?php
        //Enter your code here, enjoy!


print_r(json_decode('{"t":"\u00ed"}'));

$str = "\u9060\u50b3\u96fb\u4fe1";
echo unicode2utf8($str);

function unicode2utf8($str){
        if(!$str) return $str;
       
        $decode = json_decode($str);
        if($decode) return $decode;

        $str = '["' . $str . '"]';
        $decode = json_decode($str);
        if(count($decode) == 1){
                return $decode[0];
        }
        return $str;
}
