+Zencoder API PHP Library
+==========================
+
+Author:  [Steve Heffernan](http://www.steveheffernan.com) (steve (a) zencoder (.) com)  
+Company: [Zencoder - Online Video Encoder](http://zencoder.com)  
+Version: 1.1  
+Date:    2010-06-04  
+Repository: <http://github.com/zencoder/zencoder-php/>  
+
+For more details on the Zencoder API requirements visit  
+<http://zencoder.com/docs/api>
+
+
+ENCODING JOB
+------------
+The ZencoderJob object creates an encoding job using [cURL](http://zencoder.com/docs/glossary/curl/)
+to send [JSON](http://zencoder.com/docs/glossary/json/) formatted parameters to Zencoder's encoding API.
+
+### Step 1
+Visit the [API builder](https://app.zencoder.com/api_builder) in your account,
+and execute a successful encoding job.
+
+### Step 2
+Copy the successful JSON string, starting with the first curly brace "{",
+and pass it as the parameters for a new ZencoderJob object. Execute the script on your server to test that it works.
+
+#### Example
+    <pre>
+    <?php
+
+    // Make sure this points to a copy of Zencoder.php on the same server as this script.
+    require_once("zencoder-php/Zencoder.php");
+
+    // New Encoding Job
+    $encoding_job = new ZencoderJob('
+      {
+        "api_key": "93h630j1dsyshjef620qlkavnmzui3",
+        "input": "s3://bucket-name/file-name.avi"
+        "outputs": [
+          {
+            "label": "web"
+          }
+        ]
+      }
+    ');
+
+    // Check if it worked
+    if ($encoding_job->created) {
+      // Success
+      echo "w00t! \n\n";
+      echo "Job ID: ".$encoding_job->id."\n";
+      echo "Output '".$encoding_job->outputs["web"]->label."' ID: ".$encoding_job->outputs["web"]->id."\n";
+      // Store Job/Output IDs to update their status when notified or to check their progress.
+    } else {
+      // Failed
+      echo "Fail :(\n\n";
+      echo "Errors:\n";
+      foreach($encoding_job->errors as $error) {
+        echo $error."\n";
+      }
+    }
+
+    echo "\nAll Job Attributes:\n";
+    var_dump($encoding_job);
+
+    ?>
+    </pre>
+
+### Step 3
+Modify the above script to meet your needs.  
+Your [API Request History](https://app.zencoder.com/api_requests) may come in handy.  
+You can revisit your [API builder](https://app.zencoder.com/api_builder) to add/update parameters of the JSON.  
+
+You can translate the JSON string into nested associative arrays so that you can dynamically change attributes like "input".  
+The previous JSON example would become:
+
+    $encoding_job = new ZencoderJob(array(
+      "api_key" => "93h630j1dsyshjef620qlkavnmzui3",
+      "input" => "s3://bucket-name/file-name.avi",
+      "outputs" => array(
+        array(
+          "label" => "web"
+        )
+      )
+    ));
+
+
+GENERAL API REQUESTS
+--------------------
+A general API request can be used for all API functionality including **Job Listing**, **Job Details**, **Account Creation**, **Account Details** (even Job Creation if desired). See the [API docs](http://zencoder.com/docs/api/) for all possible API requests.
+The first argument is the **API URL**.  
+The second argument is your **API Key**.  
+The third argument is the **request parameters** if needed. It can either be a JSON string or an array of parameters.
+
+
+#### Example Job List Request
+
+    $request = new ZencoderRequest(
+      'https://app.zencoder/api/jobs',
+      '93h630j1dsyshjef620qlkavnmzui3'
+    );
+
+    if ($request->successful) {
+      print_r($request->results);
+    } else {
+      foreach($request->errors as $error) {
+        echo $error."\n";
+      }
+    }
+
+#### Example Account Creation Request
+
+    $request = new ZencoderRequest(
+      'https://app.zencoder/api/account', 
+      false, // API key isn't needed for new account creation
+      array(
+        "terms_of_service" => "1",
+        "email" => "test@example.com",
+        "password" => "1234"
+      )
+    );
+
+    if ($request->successful) {
+      print_r($request->results);
+    } else {
+      foreach($request->errors as $error) {
+        echo $error."\n";
+      }
+    }
+
+
+NOTIFICATION HANDLING
+----------------------
+The ZencoderOutputNotification class is used to capture and parse JSON data sent from
+Zencoder to your app when an output file has been completed.
+
+
+
+### Step 1
+Create a script to receive notifications, and upload it to a location on your server that is publicly accessible.
+
+#### Example
+    <?php
+
+    // Make sure this points to a copy of Zencoder.php on the same server as this script.
+    require("Zencoder.php");
+
+    // Catch notification
+    $notification = ZencoderOutputNotification::catch_and_parse();
+
+    // Check output/job state
+    if($notification->output->state == "finished") {
+      echo "w00t!\n";
+
+      // If you're encoding to multiple outputs and only care when all of the outputs are finished
+      // you can check if the entire job is finished.
+      if($notification->job->state == "finished") {
+        echo "Dubble w00t!";
+      }
+    } elseif ($notification->output->state == "cancelled") {
+      echo "Cancelled!\n";
+    } else {
+      echo "Fail!\n";
+      echo $notification->output->error_message."\n";
+      echo $notification->output->error_link;
+    }
+
+    ?>
+
+### Step 2
+In the parameters for an encoding job, add the URL for your script to the notifications array of each output you want to be notified for. 
+Then submit the job to test if it works.  
+
+**You can view the results at:**  
+<https://app.zencoder.com/notifications>
+
+#### Example
+    ...
+    "outputs" => array(
+      array(
+        "label" => "web",
+        "notifications" => array("http://example.com.com/encoding/notification.php")
+      ),
+      array(
+        "label" => "iPhone",
+        "notifications" => array("http://example.com.com/encoding/notification.php")
+      )
+    )
+    ...
+
+
+### Step 3
+Modify the above script to meet your needs.  
+Your [notifications page](https://app.zencoder.com/notifications) will come in handy.

+ * Converts to and from JSON format.
+ *
+ * JSON (JavaScript Object Notation) is a lightweight data-interchange
+ * format. It is easy for humans to read and write. It is easy for machines
+ * to parse and generate. It is based on a subset of the JavaScript
+ * Programming Language, Standard ECMA-262 3rd Edition - December 1999.
+ * This feature can also be found in  Python. JSON is a text format that is
+ * completely language independent but uses conventions that are familiar
+ * to programmers of the C-family of languages, including C, C++, C#, Java,
+ * JavaScript, Perl, TCL, and many others. These properties make JSON an
+ * ideal data-interchange language.
+ *
+ * This package provides a simple encoder and decoder for JSON notation. It
+ * is intended for use with client-side Javascript applications that make
+ * use of HTTPRequest to perform server communication functions - data can
+ * be encoded into JSON notation for use in a client-side javascript, or
+ * decoded from incoming Javascript requests. JSON format is native to
+ * Javascript, and can be directly eval()'ed with no further parsing
+ * overhead
+ *
+ * All strings should be in ASCII or UTF-8 format!
