title: Flex Datagrid select multiple rows and send to amfphp backend
body: <p>I was researching over the forums around the internet for some solution to send and ArrayCollection to AmfPHP but I didn't find good responses for that and how I can access the array on PHP side to include into a MySQL table.</p>
  
  <p>My problem:</p>
  
  <p>I have a Flex datagrid populated with some Name and Email and I want create a way to permit  users to create a group and select the Name to be part of this group. I saw in Flash Builder debugger that the data are being send good as ArrayCollection (transformed from Vector to Object also) and the problem still in how can I access this array on PHP side.</p>
  
  <p>Here is ArrayCollection being send to AmfPHP:</p>
  
  <pre><code>[0] Object (@cf87311)   
  [1] Object (@d4bfcb9)   
  [2] Object (@d4d3479)   
  </code></pre>
  
  <p>Here is the keys and values of the Array:</p>
  
  <pre><code>[0] Object (@cf87311)   
      id  "2" 
      nome    "David" 
      username    "david" 
  [1] Object (@d4bfcb9)   
      id  "3" 
      nome    "jose"  
      username    "jose@jose.com" 
  [2] Object (@d4d3479)   
      id  "4" 
      nome    "joao"
      username    "joao@joao.com" 
  </code></pre>
  
  <p>Does anyone know what I have to do to have access to the field "id" in this array ?</p>
  
  <p>Best Regards !</p>
