Shared hosting is a hosting plan where many websites share one computer. It is cheap and simple, but your host decides which PHPPHP is a programming language that builds your web pages on the computer that hosts your site, just before they reach the visitor. WordPress runs on it. versions you can use. It is the most common starting point for small business sites because it is cheap, simple and managed for you. The trade-off is that you have less control, and some of your site’s health depends on choices made by someone else.
What is shared hosting?
On shared hosting the provider manages the server and decides which PHP versions are available.
On a shared server, the provider divides the memory, processing power and disk space between all the accounts on it. Each account has its own folder and database, and you manage them through a control panelA hosting control panel, such as cPanel, Plesk or DirectAdmin, is the web page where you manage your domain, email, databases and PHP version. or by file transfer. The provider installs and updates the operating system, the web serverA web server is the program, such as Apache, Nginx or LiteSpeed, that answers when a visitor opens your site and sends back the page and files. and PHP.
That setup keeps the price low and takes server maintenance off your hands. It also means limits. There are caps on memory and run time for scripts, restrictions on which extensions you can install and sometimes a delay before new PHP versions appear in the list.
What shared hosting means for a PHP or WordPress site
The big question on shared hosting is the PHP versionA PHP version is a numbered edition of PHP, like 8.3. Each edition is looked after for a limited time, then gets security fixes only, then nothing.. Most providers let you choose a version per site in the panel, from a list that the provider maintains. If the list contains only versions that no longer get security fixes, your site is stuck until the provider adds newer ones or you move.
A shared server also means shared neighbors. A well-run provider isolates accounts from each other, but a heavy site next door can still slow yours down on a busy day, and a poorly isolated account can be a risk. Ask how the provider separates accounts and how they respond to an infected site on the same server.
Updates are split. The provider patches the server software; you keep WordPressWordPress is free software for building and editing a website in your browser.

When the PHP project releases a security updateA security patch is a software update that closes one known security weakness and adds nothing else, so installing it protects you against that problem., your provider has to roll it out on the server, and you may need to select the new version in your panel.
What to check
Look in your panel for the PHP version in use and the versions on offer. Check that backupsA backup is a separate copy of your website's files and database, so you can bring the site back after a mistake, a hack or a failed update. are included and that you know how to restore one. Find out whether you can make a copy of the site to test an update before it reaches the live version.
If the panel lacks a version you need, support can usually tell you whether and when it will come. A vague answer is information too.
When to act
Act when your PHP version is old and the plan offers nothing newer, when your site hits resource limits during normal use or when your provider announces that it will retire the version you run. If the provider offers a supported version, we can update PHP in WordPress and take care of the upgrade, with a test first. If not, the PHP migration service moves the site to a plan that fits.
Frequently asked questions
Is shared hosting safe enough for a business website?
It can be, if the provider keeps the server patched and offers a supported PHP version, and if you keep your own site updated. The shared setup means you rely on the provider for the server side and have less room to tune it.
Can I update PHP on shared hosting myself?
On many plans, yes, through a setting in the control panel. On others the provider decides. If the newest supported versions are not in the list, ask your provider when they will add them.
When should I move from shared hosting to a VPS?
Consider it when you need software the plan does not allow, when the site is slow under normal traffic or when you want more control over versions. A VPS also means more responsibility for updates, so only choose it if someone will do that work.
