+<p>Quite simply it is a way for two computers to communicate over the
+internet using XML. One computer, which we will call the client, sends
+an XML-RPC <strong>request</strong> to another computer, which we will call the
+server. Once the server receives and processes the request it will send
+back a <strong>response</strong> to the client.</p>
+<p>For example, using the MetaWeblog API, an XML-RPC Client (usually a
+desktop publishing tool) will send a request to an XML-RPC Server
+running on your site. This request might be a new weblog entry being
+sent for publication, or it could be a request for an existing entry for
+editing. When the XML-RPC Server receives this request it will examine
+it to determine which class/method should be called to process the
+request. Once processed, the server will then send back a response
+message.</p>

+<p>The above code initializes the XML-RPC class, sets the server URL and

+title and URL of your site) is placed into an array for transportation,
+and compiled using the request() function. Lastly, the full request is
+sent. If the send_request() method returns false we will display the
+error message sent back from the XML-RPC Server.</p>

+<h3><a class="toc-backref" href="#id8">Anatomy of a Request</a><a class="headerlink" href="#anatomy-of-a-request" title="Permalink to this headline">¶</a></h3>
+<p>An XML-RPC request is simply the data you are sending to the XML-RPC
+server. Each piece of data in a request is referred to as a request
+parameter. The above example has two parameters: The URL and title of
+your site. When the XML-RPC server receives your request, it will look
+for parameters it requires.</p>
+<p>Request parameters must be placed into an array for transportation, and
+each parameter can be one of seven data types (strings, numbers, dates,
+etc.). If your parameters are something other than strings you will have
+to include the data type in the request array.</p>
+<p>Here is an example of a simple array with three parameters:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$request</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span><span class="s1">&#39;John&#39;</span><span class="p">,</span> <span class="s1">&#39;Doe&#39;</span><span class="p">,</span> <span class="s1">&#39;www.some-site.com&#39;</span><span class="p">);</span>
+<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">xmlrpc</span><span class="o">-&gt;</span><span class="na">request</span><span class="p">(</span><span class="nv">$request</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>If you use data types other than strings, or if you have several
+different data types, you will place each parameter into its own array,
+with the data type in the second position:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$request</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span>
+        <span class="k">array</span><span class="p">(</span><span class="s1">&#39;John&#39;</span><span class="p">,</span> <span class="s1">&#39;string&#39;</span><span class="p">),</span>
+        <span class="k">array</span><span class="p">(</span><span class="s1">&#39;Doe&#39;</span><span class="p">,</span> <span class="s1">&#39;string&#39;</span><span class="p">),</span>
+        <span class="k">array</span><span class="p">(</span><span class="k">FALSE</span><span class="p">,</span> <span class="s1">&#39;boolean&#39;</span><span class="p">),</span>

+<p>An XML-RPC Server acts as a traffic cop of sorts, waiting for incoming
+requests and redirecting them to the appropriate functions for
+processing.</p>
+<p>To create your own XML-RPC server involves initializing the XML-RPC
+Server class in your controller where you expect the incoming request to
+appear, then setting up an array with mapping instructions so that
+incoming requests can be sent to the appropriate class and method for
+processing.</p>
+<p>Here is an example to illustrate:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;xmlrpc&#39;</span><span class="p">);</span>

+<p>The above example contains an array specifying two method requests that
+the Server allows. The allowed methods are on the left side of the
+array. When either of those are received, they will be mapped to the
+class and method on the right.</p>
+<p>The ‘object’ key is a special key that you pass an instantiated class
+object with, which is necessary when the method you are mapping to is
+not part of the CodeIgniter super object.</p>
+<p>In other words, if an XML-RPC Client sends a request for the new_post
+method, your server will load the My_blog class and call the new_entry
+function. If the request is for the update_post method, your server
+will load the My_blog class and call the <code class="docutils literal"><span class="pre">update_entry()</span></code> method.</p>
+<p>The function names in the above example are arbitrary. You’ll decide
+what they should be called on your server, or if you are using
+standardized APIs, like the Blogger or MetaWeblog API, you’ll use their
+function names.</p>
+<p>There are two additional configuration keys you may make use of when
+initializing the server class: debug can be set to TRUE in order to
+enable debugging, and xss_clean may be set to FALSE to prevent sending
+data through the Security library’s <code class="docutils literal"><span class="pre">xss_clean()</span></code> method.</p>

+<h3><a class="toc-backref" href="#id10">Processing Server Requests</a><a class="headerlink" href="#processing-server-requests" title="Permalink to this headline">¶</a></h3>
+<p>When the XML-RPC Server receives a request and loads the class/method
+for processing, it will pass an object to that method containing the
+data sent by the client.</p>
+<p>Using the above example, if the new_post method is requested, the
+server will expect a class to exist with this prototype:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">class</span> <span class="nc">My_blog</span> <span class="k">extends</span> <span class="nx">CI_Controller</span> <span class="p">{</span>
+
+        <span class="k">public</span> <span class="k">function</span> <span class="nf">new_post</span><span class="p">(</span><span class="nv">$request</span><span class="p">)</span>
+        <span class="p">{</span>
+
+        <span class="p">}</span>
+<span class="p">}</span>
+</pre></div>
+</div>
+<p>The $request variable is an object compiled by the Server, which
+contains the data sent by the XML-RPC Client. Using this object you will
+have access to the <em>request parameters</em> enabling you to process the
+request. When you are done you will send a Response back to the Client.</p>
+<p>Below is a real-world example, using the Blogger API. One of the methods
+in the Blogger API is <code class="docutils literal"><span class="pre">getUserInfo()</span></code>. Using this method, an XML-RPC
+Client can send the Server a username and password, in return the Server
+sends back information about that particular user (nickname, user ID,
+email address, etc.). Here is how the processing function might look:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">class</span> <span class="nc">My_blog</span> <span class="k">extends</span> <span class="nx">CI_Controller</span> <span class="p">{</span>

+<h3><a class="toc-backref" href="#id12">Formatting a Response</a><a class="headerlink" href="#formatting-a-response" title="Permalink to this headline">¶</a></h3>
+<p>Similar to <em>Requests</em>, <em>Responses</em> must be formatted as an array.
+However, unlike requests, a response is an array <strong>that contains a
+single item</strong>. This item can be an array with several additional arrays,
+but there can be only one primary array index. In other words, the basic
+prototype is this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$response</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span><span class="s1">&#39;Response data&#39;</span><span class="p">,</span> <span class="s1">&#39;array&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>Responses, however, usually contain multiple pieces of information. In
+order to accomplish this we must put the response into its own array so
+that the primary array continues to contain a single piece of data.
+Here’s an example showing how this might be accomplished:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$response</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span>
+        <span class="k">array</span><span class="p">(</span>

+<p>Notice that the above array is formatted as a struct. This is the most
