title: Change PHP ini values using provisioning
body: <p>What is the best way to change PHP ini values when provisioning a Homestead box?</p>
  
  <p>E.g. I want to change the value of <code>display_startup_errors</code> to <code>On</code>.</p>
  
  <p>Would you find/replace the value in the <code>php.ini</code> file using <code>sed</code>? </p>
  
  <p>Do I just put the commands in <code>after.sh</code> or is it better to use <code>config.vm.provision "shell"</code>?</p>
