Seems there is problem for your source(location) of file provisioner.you haven't specify the exact path where index.php file is there. To resolve the issue plese specify full path for source.This might be reason your getting error.

provisioner "file" {
    connection {
      type        = "ssh"
      user        = var.vm_admin_username
      host        = "${azurerm_public_ip.main.ip_address}"
      private_key = tls_private_key.main_ssh.private_key_pem
      agent       = false
      timeout     = "5m"
    }
    source      = "{path}/index.php"
    destination = "/tmp/index.php"
  }
