PHP Website Development Services in India

Secure, maintainable PHP development for custom websites, WordPress extensions, business logic and server-side features that off-the-shelf tools cannot provide.

Discuss PHP Development

The Server-Side Language Behind Much of the Web

PHP is a server-side programming language. When a visitor opens a page, PHP code runs on the web server, reads data, applies business rules, and sends the finished HTML to the browser. It powers WordPress and many other content management systems, frameworks and custom web applications. Because it is mature, widely supported by hosting providers and backed by a huge ecosystem, PHP remains a practical, cost-effective choice for a large share of business websites.

Most businesses never need to think about PHP directly. Their website runs on a platform, and plugins or themes cover the common needs. PHP development becomes important when you need something specific: a custom feature that no plugin provides, an integration with your internal systems, a WordPress plugin built for your workflow, a fix for a slow or insecure legacy site, or a custom web application with your own business rules.

ViV Softech Solution is a website designing and digital marketing agency based in Delhi. Our developers build and maintain PHP code for businesses across India, from small custom features to full custom websites. This page explains what we build with PHP, how we approach security and code quality, how we work with WordPress and frameworks, how we handle legacy code, and what affects cost and timeline. We aim to be practical: if a reliable existing plugin solves your problem, we will tell you instead of writing custom code for its own sake.

What We Build With PHP

Custom PHP Websites

Websites built around your exact requirements when a standard CMS is not the right fit.

Custom WordPress Plugins

Purpose-built plugins that add features, custom post types, settings and workflows to WordPress.

Integrations and APIs

Server-side connections to CRMs, ERPs, payment gateways, SMS, email and other third-party services.

Business Logic and Forms

Quote calculations, eligibility checks, multi-step applications and automated notifications.

Security Fixes and Hardening

Code reviews, vulnerability fixes and safer handling of input, sessions and file uploads.

Legacy Code Upgrades

Updating older PHP code to supported versions and modern practices without losing functionality.

When You Need Custom PHP Development

A feature no plugin provides properly

Plugins are excellent for common needs, but they are built for everyone. If you have combined three plugins and custom snippets to approximate one business process, a single focused piece of custom code is often more reliable, faster and easier to maintain.

Integration with your own systems

Sending website enquiries into your CRM, syncing stock with an inventory system, pulling prices from an ERP or pushing orders to a courier service usually needs server-side code that talks to those systems securely.

Specific business rules

Pricing that depends on several inputs, approval workflows, role-based content, or rules required by your industry are typical cases where off-the-shelf tools fall short.

Performance or security problems

Slow pages, database overload, errors after PHP version upgrades or security warnings often trace back to inefficient or outdated code that needs a developer’s attention.

An ageing custom website

Many businesses run websites built years ago in custom PHP. When the original developer is unavailable and the code runs on an unsupported PHP version, the site becomes a risk. We can stabilise, upgrade or plan a migration.

Security Practices We Follow

Server-side code handles your data and your customers’ data, so security cannot be an afterthought. Our PHP work follows established secure coding practices:

Validate and sanitise all input: nothing that comes from a form, URL or API is trusted without checking.
Prepared statements for database queries: to prevent SQL injection.
Output escaping: to prevent cross-site scripting when displaying user-supplied content.
Nonces and CSRF protection: so actions cannot be triggered by malicious third-party pages.
Proper authentication and capability checks: users only see and do what their role allows.
Safe file uploads: file type checks, size limits and storage outside executable paths where possible.
Secure password handling: modern hashing functions, never plain text.
Secrets management: API keys and credentials kept out of public code and version control.
Supported PHP versions: code written for currently supported releases, with deprecation warnings addressed.
Error handling: errors logged privately rather than displayed to visitors.

No system is ever completely immune to attack, and we will not claim otherwise. Following these practices, combined with updates, backups and monitoring, greatly reduces risk.

Code Quality and Maintainability

Readable, documented code

Code is read many more times than it is written. We use clear naming, consistent formatting and comments where the reasoning is not obvious, so another developer can understand it later.

Recognised coding standards

We follow widely used PHP coding standards, and WordPress coding standards for plugins and themes.

Version control

All work is tracked in Git, so every change is recorded and can be reviewed or reversed.

Separation of concerns

Business logic, data access and presentation are kept separate, making the code easier to test and change.

Staging before production

Changes are tested on a staging copy of your site before going live, protecting your live website and visitors.

No lock-in

Custom code written for your project is yours. We document it so you are not dependent on us to maintain it.

PHP With WordPress and Frameworks

Extending WordPress the right way

WordPress is written in PHP and designed to be extended. We use its hooks, custom post types, custom fields, REST API and settings APIs to add functionality in a way that survives core, theme and plugin updates. Custom functionality lives in a dedicated plugin or child theme, never in edited core files.

Custom post types and fields

Structured content such as properties, courses, doctors, projects or job openings is best stored as custom content types with defined fields. This makes the content easy to manage, filter and display consistently.

PHP frameworks for custom applications

For larger custom applications, a mature PHP framework provides routing, database tools, authentication and testing support. We recommend a framework only when the project’s complexity justifies it.

Choosing between WordPress, a framework and plain PHP

WordPress suits content-led websites with editing needs. A framework suits custom applications with complex business logic. Plain PHP may suit very small, focused scripts. We explain the trade-offs in cost, flexibility and maintenance before recommending one.

Working With Legacy PHP Code

Inheriting an older PHP website is common. The code may be undocumented, written for an old PHP version and full of workarounds. We approach legacy projects carefully:

Take a full backup of files and database before touching anything.
Set up a staging copy where changes can be tested safely.
Audit the code for security risks, deprecated functions, performance bottlenecks and dependencies.
Report findings in plain language with priorities and options.
Fix critical issues first, such as security vulnerabilities and fatal errors.
Upgrade incrementally to a supported PHP version, testing as we go.
Recommend a long-term path: maintain and improve, refactor in stages, or migrate to a modern platform.

We give honest assessments. Sometimes the most cost-effective option is to rebuild on WordPress or a framework rather than keep patching old code.

Our Development Process

1. Requirements: we document what the feature or system must do, who uses it and what it connects to. 2. Technical plan: we choose the approach, estimate effort and identify risks. 3. Development: we build in small increments on a staging environment with version control. 4. Testing: we test functionality, edge cases, security basics and performance. 5. Review: you test on staging and give feedback. 6. Deployment: we release to production with a backup and rollback plan. 7. Documentation and support: we hand over notes and offer optional maintenance.

What Affects Cost and Timeline

Feature complexity: number of rules, user roles, screens and data types.
Integrations: each external system adds work, especially if its documentation is limited.
Existing code condition: clean code is quicker to extend than undocumented legacy code.
Security and compliance requirements: sensitive data needs extra safeguards and testing.
Admin interfaces: screens for your team to manage data add scope.
Testing depth and documentation: larger systems need more structured testing.
Hosting environment: server limitations may affect what is possible.

We provide a written estimate after reviewing requirements and, for existing sites, the current code.
