Hosting Terms
What is PHP?
PHP in plain English — the meaning, the comparison, and why it matters to anybody running a website.
Straight answer first
PHP is the server-side language behind most of the web's dynamic sites — WordPress, WooCommerce and the bulk of the CMS world all run on top of it.
Below: the fuller explanation, a picture that makes it stick, why it matters in practice, and where you will actually run into it.

To read, naturally
Any page that differs from one visitor to the next — a login, a basket, a search result — is PHP assembling HTML on demand, usually pulling the pieces out of a MySQL database. The 8.x generation runs dramatically faster than the versions its dated reputation is based on.
On hosting, the PHP version is a per-site setting, and it is one of the cheapest levers you have on both speed and security, because old releases are slower and unpatched at the same time.
The picture that makes PHP stick
The kitchen behind the menu board. Static files are the sandwiches already made up in the chiller; PHP cooks each dynamic page to order from what is in the store cupboard, and how modern the kitchen is decides how fast the food arrives.
Comparisons simplify, naturally — but this one holds together well enough to reason with, and reasoning is the whole point of a glossary.
What is actually at stake
Your WordPress site is a PHP application. Its speed rides on the PHP version and OPcache, its security rides on staying with supported releases, and on decent hosting both of those are a dropdown menu rather than a project.
You do not need to work at this layer every day. You need to recognise it when it explains something, which is exactly the moment this page earns its keep.
One concrete example
Moving a site from PHP 7.4 to 8.3 in the panel visibly cuts the time the admin screens take to load. Same code, newer engine, five minutes including a click through the site to check nothing broke.
Perfectly ordinary once you have seen it, which is rather the point: most hosting concepts are simple machinery wearing an intimidating name.
Where you will meet it on our platform
On our hosting this largely looks after itself — the platform applies sensible defaults, and the panel hands you the controls when you want them. The concepts worth reading next: MySQL, WordPress, OPcache and CMS.
SSL comes free with every plan and reissues itself before it lapses, so nobody has to diary the padlock.
Unexplained jargon is bad service
Every confusing term in hosting turns into a support ticket sooner or later, so we defined the hundred most common ones properly, once, in the plain English we would use across the counter.

PHP defined, pictured by comparison and placed in your own control panel — recognise-level in a single read.

Across the Counter
The questions we get asked most
Is PHP an outdated language now?
The reputation is; the language is not. The engine work in PHP 8 made it one of the quicker interpreted runtimes going, and it still executes most of the web. The genuinely outdated thing is a site still sitting on 7.x in 2026.
Do I need to learn PHP to run a WordPress site?
No — WordPress hides it completely for everyday use. A little awareness helps at the edges: reading an error log, understanding what a version upgrade changes, and working out why one ancient plugin is blocking the whole upgrade.
Can I bring a domain I already own?
Yes, and transfers in are routine. Unlock the name at your present registrar, collect the auth code, then start the transfer from your client area. Whatever registration time is left comes across with it, and DNS keeps answering the whole way through.
Do you shift an existing site across at no charge?
We do. Open a ticket with the login details for your current host and the whole lot comes over: files, databases, mailboxes and configuration. You check the copy before DNS changes hands, and the old site keeps serving customers until the new one takes the traffic, so nobody ever sees a gap.
What uptime do you commit to, and who is watching?
We commit to 99.9% uptime and watch it continuously. That figure is an operational target rather than a poster line, and the alerting behind it usually has an engineer on a problem before the first customer notices anything is wrong.
How do I read the mail when I am away from the desk?
Webmail opens in any browser, and every mailbox also speaks IMAP, POP and SMTP — so the mail app on your phone, the client on your desktop and webmail all show the same messages in the same order.
Can one plan hold more than a single website?
From the Pro tier upward, yes — several sites, each with its own domain, mailboxes and certificate, all under one account. If those extra sites belong to clients rather than to you, reseller hosting is the better fit: it gives each one proper separation.

Packing up and moving host? Take our checklist.
A plain running order for a move nobody notices: what to copy first, how to carry email across without dropping a single message, when to point DNS, and the two slips behind nearly every hour of downtime we get called about.
Whenever you're ready to order.
Every plan carries the essentials other hosts ring up as extras — and support that actually replies.
