Post to wordpress via php - php

Question

I'm trying to post on my wordpress site using php .
I used php to fetch data from a website and stored all of them in variables .
I found the code to a few auto wordpress php posters but they are kind of complex and i'm not really sure how to use/alter them.
What the simplest way to do it via php ?
My data are like :
$topic_name = "name";
$mainimage = "url/image":
$input = "hello................." ;
$category = "cars";
$tags = ("tag1","tag2","tag3"...);
Note : I just need the basic code to login to my wordpress and post some random text via php - I'm pretty sure i can figure out how to input the category , tags etc later on.
I'm trying to use this one as it seem simple but i don;t think it works for the latest version of wordpress (3.7.1 ) -
I am using xampp for hosting the site locally for now
If anyone can modify it or can share a working one , would be great .
function wpPostXMLRPC($title,$body,$rpcurl,$username,$password,$category,$keywords='',$encoding='UTF-8') {
$title = htmlentities($title,ENT_NOQUOTES,$encoding);
$keywords = htmlentities($keywords,ENT_NOQUOTES,$encoding);
$content = array(
'title'=>$title,
'description'=>$body,
'mt_allow_comments'=>0, // 1 to allow comments
'mt_allow_pings'=>0, // 1 to allow trackbacks
'post_type'=>'post',
'mt_keywords'=>$keywords,
'categories'=>array($category)
);
$params = array(0,$username,$password,$content,true);
$request = xmlrpc_encode_request('metaWeblog.newPost',$params);
$ch = curl_init();
curl_setopt($ch, CURLOPT_POSTFIELDS, $request);
curl_setopt($ch, CURLOPT_URL, $rpcurl);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 1);
$results = curl_exec($ch);
curl_close($ch);
return $results;
}

Do you really need to use XML-RPC? This is generally what you would want to do to post to a remote WordPress installation. For instance, from a completely different site, from a mobile app, etc.
It sounds like you are writing a plugin that will run within your WordPress installation. In that case you can just call wp_insert_post() directly.
A very trivial example from WordPress's wiki, which also has a complete list of parameters you can use:
// Create post object
$my_post = array(
'post_title' => 'My post',
'post_content' => 'This is my post.',
'post_status' => 'publish',
'post_author' => 1,
'post_category' => array(8,39)
);
// Insert the post into the database
wp_insert_post( $my_post );
