title: PHP save file to users computer
body: <p>I have a script that creates a vCard for members of staff when the 'Add Contact' button is clicked. I have this vCard in a variable, but I'm not really sure what to do with it next. </p>
  
  <p>I take it that my frist step should be to save this file on the server?</p>
  
  <p>I'd like to just have a box pop up and allow people to download and save the vCard, so if the step about is not necessary I'd like to just skip it.</p>
  
  <p>Any pointers here would be appriciated.</p>
  
  <p>Thanks.</p>
