The short answer for owners deciding how to look after their site
Neither WordPress nor custom PHP is maintenance-free; they simply need different kinds of care. A WordPress site needs frequent, smaller updates from many independent sources, and the main risk is that those pieces stop working well together. A custom PHP site needs fewer but heavier updates, and the main risk is depending on the one developer who understands the code.
This article explains why, compares the two side by side, and helps you decide which suits your organisation. It assumes you already have one or the other and want to know what looking after it really involves. General security habits that apply to every site, such as backups and passwords, are covered in our guide to website security updates and backups.
How a WordPress site is put together
WordPress is an open-source content management system. A typical business site built on it has four parts: the WordPress core, a theme that controls the design, a set of plugins that add features (contact forms, galleries, SEO settings, caching, sometimes a shop), and often a page builder for laying out pages visually.
Each of these parts is written and updated by a different team on its own schedule. WordPress core is maintained by its open-source project and documented on WordPress.org. A theme might come from a commercial marketplace, a forms plugin from one company and a gallery plugin from a single volunteer developer. That variety is what makes WordPress quick to build with, and it is also what makes its maintenance a coordination job.
Routine WordPress maintenance: updates, conflicts and abandoned plugins
Updates in the right order
Updates arrive often, sometimes several in a week across core and plugins. A sensible routine is to take a backup, update on a copy of the site first for anything significant, update plugins one by one or in small groups, and then check key pages. Updating twenty plugins at once on the live site and finding a broken page an hour later leaves you guessing which one caused it.
Plugin conflicts
A conflict happens when an update to one plugin changes something another plugin or the theme relied on. Picture a school website where updating the gallery plugin suddenly pushes the admission form below the footer on mobile phones. Nothing is "hacked" and nothing is obviously broken on a computer, yet parents on phones cannot find the form. Conflicts are the most common reason WordPress owners hesitate to update, and the answer is testing, not skipping updates.
Abandoned, premium and pirated plugins
Some plugins stop receiving updates when their developer moves on. They may keep working for a while but will not receive security fixes, so they should be replaced. Premium themes and plugins usually need an active licence to receive updates, and someone must track those renewal dates. Pirated ("nulled") versions of premium themes are a well-known source of hidden malicious code and should never be used on a business site.
How a custom PHP website is put together
A custom PHP website is written specifically for your organisation. It may be plain PHP, or built on a framework such as CodeIgniter or Laravel that provides a standard structure. It typically uses a few third-party libraries for tasks like sending email or generating PDFs, a MySQL or similar database, and an admin panel designed around how your staff work.
Custom builds are common when a website does more than publish pages: a dealer login with price slabs, an online fee payment page linked to a school's records, or a booking flow with rules specific to the business. There are far fewer moving parts from outside sources, but the logic that holds everything together exists only in your code.
Routine custom PHP maintenance: PHP versions, framework upgrades and documentation
PHP version changes
Each PHP version receives security support for a limited period, published on the PHP supported versions page. Hosting companies eventually move customers to newer versions. Code written years ago may use functions that newer PHP versions have changed or removed, so a hosting upgrade can break pages without anyone touching your site. Good maintenance checks compatibility before the host forces the change.
Framework and library upgrades
Minor framework updates are usually straightforward. Moving to a new major version can involve real development work, similar to a small project, and is easy to postpone for years. Postponing too long leaves the site on a version that no longer receives security fixes.
Documentation and developer dependency
The biggest maintenance risk on a custom site is knowledge. If only one developer knows how the code works and there is no documentation, every change depends on that person's availability. Before the build ends, or at the start of any maintenance arrangement, make sure you hold the full source code, database access, server credentials and at least basic notes on how the main features work.
Side-by-side comparison
| Aspect | WordPress | Custom PHP |
|---|---|---|
| How often updates arrive | Frequently, from core, theme and each plugin | Less often; PHP, framework and libraries |
| Who publishes fixes | Many independent developers | Framework project plus your own developer |
| Main day-to-day risk | Plugin and theme conflicts after updates | Old code breaking on newer PHP versions |
| Exposure to automated attacks | Higher, because the platform is widely used | Lower, but own bugs may go unnoticed |
| Content editing by staff | Usually easy through the dashboard | Only as easy as the admin panel built for it |
| Adding a new feature | Often a plugin, if a reliable one exists | Developer work, built to your rules |
| Dependency on one person | Lower; many developers know WordPress | Higher unless code is documented |
| What you must keep track of | Plugin list, licence renewals, update log | Source code, documentation, PHP and framework versions |
Which suits whom
WordPress suits organisations whose website is mainly about content that staff update often: news, notices, galleries, service pages, blog posts. A coaching centre posting results, a hospital updating doctor timings or a firm publishing articles will find its editing tools convenient, and maintenance stays manageable if the plugin list is kept short.
Custom PHP suits sites tied closely to business logic: dealer or customer portals, integrations with ERP or billing software, calculators, booking rules or anything no plugin does properly. The extra effort in maintenance buys you a site that does exactly what your process requires.
Many organisations sensibly use both: WordPress for public pages and a custom application for the portal behind a login. If you are planning a new site and weighing these choices against budget, our analysis of website cost factors in India covers how the platform choice affects build and running costs.
How MATROP maintains both kinds of site
MATROP's website maintenance plans are scoped according to the site's technology, whether WordPress, PHP or custom, along with the number of pages and the support needed. For WordPress sites the routine covers core, theme and plugin updates, conflict checks, security patches and backups. For custom PHP sites it covers bug fixes, compatibility checks, performance tuning, backups and agreed content changes. Every plan begins with an audit and includes a monthly report of work done and recommendations.
There are limits worth stating plainly. If a custom site was built by someone else and the source code is not available, we cannot maintain it properly until access is sorted out. If a site runs on a framework or PHP version so old that it cannot be safely updated, the honest first step may be a stabilisation project or a rebuild rather than a monthly plan, and we will say so after the audit.
Questions people ask
Is WordPress less secure than a custom PHP website?
Not by nature. WordPress is targeted more often because it is so widely used, but a site with few, well-maintained plugins and regular updates is reasonably safe; a custom site faces fewer automated attacks, yet its own bugs may go unnoticed if nobody reviews the code.
Can a different developer maintain our custom PHP website?
Yes, provided they receive the complete source code, a copy of the database, server access and whatever documentation exists. Without documentation it still works, but the first few weeks go into understanding the code, which costs time.
How many WordPress plugins is too many?
There is no fixed number. Each plugin should do a clear job, still receive updates from its developer, and be removed if nobody uses it; several plugins doing overlapping jobs are a common cause of conflicts and slow pages.
Should we rebuild our site on a different platform to reduce maintenance?
Rarely on maintenance grounds alone. Switching platforms is a rebuild with its own cost and risk, so it is usually better to decide at the time of a planned redesign, based on how you need to edit and extend the site.
