PHP

Hi All,

I am writing a XML RPC in PHP but am having error. here below is the code

clients.php

<?php      
/* Include the library */      
include ( "kd_xmlrpc.php" );      
     
/* Define variables to find the rpc server script */      
$site = "localhost";
$location = "/xml-rpc/server.php"; 


function convert_date ( $date ) {      
   $date = date ( "D M y H:i:s",XMLRPC_convert_iso8601_to_timestamp ( $date ) );      
   return ( $date );
}   
$response=array();
list($success, $response) = XMLRPC_request($site,$location,'sum.add', array(XMLRPC_prepare(2),"4"));

if($success){
	echo $response[0];
}
?>

server.php

&lt;?php      
/* Include the library */      
include ( "kd_xmlrpc.php" );  
include ( "config.php" );  


/* Now use the XMLRPC_parse function to take POST     
  data from what xml-rpc client connects and turn     
  it into normal PHP variables */  
request=XMLRPC_parse($GLOBALS['HTTP_RAW_POST_DATA']); 

/* From the PHP variables generated, let's get the     
  method name ie. server asks "What would you like     
  me to do for you?" */    
$methodName = XMLRPC_getMethodName($request);

/* Get the parameters associated with that method     
  e.g "So you want to view a news item. Tell me     
  which one you want. What's the id#?" */    
$params = XMLRPC_getParams($request);
$param=$params[0];

$param+=$param;

XMLRPC_response(XMLRPC_prepare($param),KD_XMLRPC_USERAGENT);

$sql="INSERT INTO `tests`.`tests` (`id` ,`method` ,`data` )VALUES (NULL , '$methodName', '$param')";
mysql_query($sql) or die(mysql_error());
?&gt;

the error am getting is Notice: Uninitialized string offset: 0 in C:\wamp\www\xml-rpc\client.php on line 18

Kindly help

$response array is not populated by the time it is needed?

if($success){
echo $response[0];
}

You may want to change to:
if($success){
print_r ( $response );
}

The error has disappeared but it is not printing anything. where am i going wrong

That means that the if ($success) statement is never being run now because it is never true.
Looks like the problem is elsewhere.

What is $success anyways? Where is this being populated from?
