title: why is php's ini_set function switched off on shared hosts
body: <p>I am using hosting on VPS and they've not allowed me to use php's ini_set function to set configuration at runtime, on a script by script basis. Instead I must change the settings directly in the php.ini file which is a mission to access via SSH. </p>
  
  <p>Why is this?</p>
  
  <p>This, although fine, is slightly annoying as I have 12 domains on the shared server and I do not neccessarily want to set the settings across the board....</p>
