Job boards, freelance platforms, third-party IT vendors, and social media channels are the main places where you can find PHP programmers for hire. However, to decide which one you should choose, determine the employment model that suits your budget, objectives, and deadline. Freelance platforms (e.g., Upwork, Arc.dev) are perfect for hiring developers when you have one-time tasks and low-scale projects.
Long-term projects that require continuous development and constant support require in-house specialists whom you can hire via popular job boards (e.g., Indeed, Glassdoor) or social media channels (e.g., Linkedin). Finally, hiring PHP developers from IT vendors is preferable for startups with vague requirements, businesses that are looking for profound domain knowledge, and companies that want to go for outsourcing to lower development costs.
