AI assistants have become part of many developers' daily work, from writing boilerplate code to explaining errors. AI coding tools for developers come in several forms, and used well they save real time. Used carelessly, they introduce bugs and security holes. Here's a balanced guide.
Tools and features change quickly; evaluate current versions and terms.
Types of AI coding tools
- In-editor assistants: suggest code as you type (e.g. GitHub Copilot and similar extensions)
- Chat assistants: general AI models you ask to explain, write or review code
- AI-first editors and agents: editors that can edit multiple files or run tasks with your approval
- Code review and testing helpers: suggest tests, find issues in pull requests
What AI does well
- Boilerplate: forms, CRUD screens, validation, SQL queries
- Explaining unfamiliar code or error messages
- Converting between formats (CSV to SQL, JSON to PHP arrays)
- Writing first drafts of tests and documentation
- Regex, shell commands and small scripts
- Refactoring suggestions
Where AI goes wrong
- Confident but wrong code: functions that don't exist, outdated APIs
- Security issues: SQL built by string concatenation, missing input validation, weak password handling. See PHP security basics
- Subtle logic bugs in edge cases (time zones, money rounding, GST calculations)
- Over-complicated solutions for simple problems
Good practices
- Review every line. You are responsible for the code, not the AI
- Never paste secrets (passwords, API keys, customer data) into AI tools
- Check your organisation's and client's policies on AI use and data
- Run and test the code: unit tests, real data, edge cases
- Use version control so changes are reviewable and reversible. See Git basics
- Ask for explanations, not just code. It helps you learn and spot mistakes
- Be specific: give context (PHP version, framework, database schema)
Licensing and ownership
Understand each tool's terms for code ownership and training data. Some offer settings to avoid suggestions matching public code. For client work, be transparent about tools you use if required.
For business owners hiring developers
AI can make good developers faster; it doesn't replace understanding. Ask developers how they review AI-generated code for security and quality.
FAQs
Will AI replace web developers?
AI changes how developers work, automating routine tasks, but businesses still need people who understand requirements, architecture, security and quality.
Is AI-generated code safe to use in production?
Only after proper review and testing, like any other code.
