PHP Web Development Services: What They Cover and When PHP Fits

PHP is the server-side language behind a large share of the web, mainly because WordPress runs on it. W3Techs reported on 5 October 2026 that PHP is used by 69.8% of all websites whose server-side language it can identify, and that WordPress powers 40.1% of all websites. That shows PHP is mature and widely supported. It does not make PHP the right tool for every project. This guide explains what PHP development services include, when PHP fits, why the PHP version matters, what drives cost and how to choose a partner.

What PHP web development services cover

• Custom web applications and portals. Customer portals, internal tools, booking and workflow systems, usually built on a framework such as Laravel or Symfony.
• CMS development. WordPress themes, plugins and integrations, or other PHP-based content management systems, so your team can manage content without developer help.
• E-commerce. Stores on WooCommerce or Magento (Adobe Commerce), plus payment, inventory and order-tracking integrations.
• APIs and integrations. Connecting your site to payment providers, SMS and email services, CRMs and logistics systems.
• Upgrades and legacy work. Moving older PHP applications to supported versions, fixing performance and security problems.
• Maintenance. Updates, security patches, monitoring, bug fixes and enhancements after launch.

When PHP fits, and when something else does

Our view: choose the stack your team can maintain, that fits your hosting and integrations, and that will still be supported in five years. The language's reputation matters less than any of those. Our guides to Magento vs Shopify and WooCommerce vs Shopify help when the question is about stores.

PHP versions and support: the detail that matters most

Each PHP branch is fully supported for two years from its first stable release, then for two more years with critical security fixes only, after which it reaches end of life (php.net). As of October 2026, the supported branches are:

PHP 8.1 reached end of life on 31 December 2025, 8.0 on 26 November 2023 and 7.4 on 28 November 2022. The last PHP 5 release, 5.6, ended on 31 December 2018. Yet W3Techs data from the same month shows that, among websites using PHP, 27.7% still run PHP 7 and 7.8% run PHP 5. Unsupported versions receive no security fixes, so php.net urges anyone using them to upgrade.

Other projects set their own floors. WordPress recommends a host that supports PHP 8.3 or greater, and says versions that have reached end of life may expose your site to security vulnerabilities. Laravel releases a major version about every year, with bug fixes for 18 months and security fixes for two years; Laravel 13, released on 17 March 2026, requires PHP 8.3 or higher. WooCommerce also recommends PHP 8.3 or greater, and each Adobe Commerce release lists the PHP versions it supports, so a store's platform and PHP versions have to be upgraded together. The practical lesson: version upgrades are routine work that should be planned, quoted and scheduled, not a surprise.

Frameworks, CMS and code quality

• Framework or no framework. For anything beyond a small tool, we recommend a mature framework over hand-rolled code. It standardises structure, security helpers and testing.
• CMS choice. WordPress suits content-led sites. Its plugins are a convenience and a maintenance obligation, so keep them few and well maintained.
• Practices to expect. Prepared statements for database queries, validated input and escaped output, hashed passwords, dependencies managed with Composer and checked for known vulnerabilities, secrets kept out of the code, HTTPS everywhere, automated tests, code review, CI/CD, backups and logging.

Upgrading an existing PHP site

Signs that you need an upgrade: the site runs on PHP 8.1 or older, the CMS or framework is several major versions behind, plugins are abandoned, or nobody can say which PHP version is in use. A sensible path is to audit the code and dependencies, upgrade in steps (PHP, then framework, then packages), test thoroughly in a staging copy, deploy with a rollback plan and add automated tests so the next upgrade is cheaper. A rewrite is justified only when the architecture itself is the problem. Mindrops' legacy modernization service covers this kind of work.

What drives cost and timeline

We don't publish price ranges, because a figure without your scope would be misleading. The drivers are:

• Scope. Features, user roles and the number of screens.
• Build approach. Custom code costs more up front than configuring a CMS or plugin, but can cost less to run if you would otherwise pile up workarounds.
• Integrations. Each external system adds build, testing and ongoing maintenance.
• Existing code. Old versions, missing tests and undocumented behaviour all raise effort.
• Quality bar. Security testing, performance work, accessibility and documentation.
• Hosting and DevOps. Environments, deployment pipelines, monitoring and backups.
• Team and support model. Seniority of the people involved, and whether you need a retainer after launch.

How to choose a PHP development partner

• Version policy. Which PHP and framework versions they will use, and how they handle upgrades.
• Security practice. How they test for vulnerabilities and how they manage dependencies.
• Quality process. Version control, code review, automated tests and staged releases.
• Honest advice. Willingness to recommend another stack, or a ready-made platform, when it fits better.
• Ownership. Your organisation owns the code, repositories and hosting accounts.
• Documentation and handover that lets another team take over.
• Support terms. Response times, patching and upgrade cadence in writing.
• Verifiable work. Live products or case studies, and references you can contact.

How Mindrops works on PHP projects

Mindrops builds on PHP alongside Node.js, .NET and Python, and recommends the stack that fits the project. Its website development service covers corporate sites, CMS platforms and portals, with e-commerce, API integration and custom web application development for larger systems. Security testing is available through penetration testing and VAPT, and maintenance continues after launch. The client owns the source code, with documentation and knowledge transfer included.

Conclusion

PHP is a sound choice for content sites, stores and many business applications, provided it is kept on a supported version and maintained properly. Ask about versions, security and ownership before you ask about price. When you are ready to scope a project, get a quote and we will respond within one business day.
