PHP: Upgrading to PHP 7.x

Guide below is to help you plan your PHP upgrade strategy, and ensure HostBill works stable with no ioncube-broken files.
This article assumes you're using HostBill on php 5.6 or 7.0 and plan to upgrade to 7.x. You should consider performing upgrade during lowest possible traffic.

Upgrade to latest Ioncube Loaders


First, ensure that you are using latest Ioncube Loaders.
HostBill requires at least ionCube version 10.1 to function properly. Upgrade procedure for latest ioncube loaders can vary depending on server/software HostBill is deployed on:

  • For HostBill installed using Enterprise script, refer to this guide: Upgrade Ioncube loaders to latest version
  • For HostBill installed on WHM/cPanel, refer to EasyApache guide to update your software profile with latest ioncube
  • For HostBill installed on Plesk: When this article was written latest loaders were part of php 7.2 profile in Plesk, previous php versions requires updating loaders manually.


Upgrade to latest HostBill version


Once ioncube loaders are updated, we need to update to latest HostBill version. To do that, use Auto-Upgrade plugin, as with any other update or proceed with manual update. Refer to Auto-Upgrade plugin FAQ in case of any issues with it.


Download latest plugin versions


HostBill ships its plugins in separate zip files, so you need to update them separately to make sure they support PHP version you plan to upgrade to.

Fortunately, we provide fast & effortless way of doing this:

  • Login to license management portal at https://clients.hostbillapp.com/
  • Under "Services" locate license you wish to download all plugins for
  • Click on "Download all plugins
  • Follow guide displayed on screen

Upgrade PHP to target version


Before doing this, consider enabling Maintenance Mode in your HostBill general settings.

Now its time to upgrade PHP to desired version. Procedure differs, depending on server/software HostBill is installed on.

  • Please consult related software vendor documentation for php upgrade guides.
  • Please ensure that installed PHP version consist all HostBill-required PHP extensions (System requirements)
