PHP Developer Hiring Checklist: Skills, Salaries & Interview Questions

Hiring the right PHP developer is a critical pick that can make or break your development pipeline. As a tech company that is in the race to develop scalable web apps, eCommerce platforms, or custom CRMs, PHP stands as a powerful and widely used backend technology. Choosing the wrong fit can have negative consequences such as messy codebases, costly rewrites, and long development delays. 

If you want to make your mark and sustain competitiveness of the hiring landscape you need to go a step further than just finding someone who knows PHP. You need to identify a developer who exhibits strong technical fundamentals, updated framework knowledge, and solid soft skills. PHP has remained the powerhouse of web development for quite some time now, and the trend is expected to continue. 

Hiring PHP developers comes with its unique setbacks, such as outdated resumes, inconsistent portfolio quality, or limited exposure of developers to modern tools such as Docker, Composer, and CI/CD. Additionally, the growing complexity of picking amongst the emerging hiring approaches and the need for a structured and scalable process becomes a pressing priority. 

This is where this blog aims to serve its purpose by offering a walkthrough of the must-have skills, salary insights, interview questions, and a hiring checklist. Consider this as your PHP developer hiring guide to help you make informed hiring decisions confidently. Once you give it a read, there’s no more room for guesswork or a trial-and-error approach.

Must-Have Skills for a PHP Developer

There are several skills that matter and make up the comprehensive PHP developer skills checklist. It’s not just the technical side of it that matters, but soft skills account for equal weight in the skills checklist.

The following table will offer you better clarity regarding the skills you must assess when hiring a PHP developer:

What’s the PHP Developer Salary in 2025? (US Benchmarks)

After evaluating the PHP developer skill set, it’s time to conduct thorough research of the salary benchmarks in the industry and formulate a competitive compensation. When your offering is a step ahead of your rivals, only then can you have a first-mover advantage in attracting and retaining top PHP talent. 

Depending on experience, location, skill set, economic conditions, market demand, and several such hiring factors, PHP developer salaries can greatly vary. For instance, if you choose to hire PHP developers from the USA, the PHP developer salary US estimates based on experience will be something as follows:

  • Junior- level developer: $64,000 to $74,000
  • Mid-level developer: $83,000 to $115,000
  • Senior-level developer: $124,000 to $163,000

Let’s say if you opt to hire PHP developers from India, the average salary estimates based on experience will be:

  • Junior- level developer: starting from $26,000
  • Mid-level developer: starting from $27,000
  • Senior-level developer: starting from $33,000

While remote roles tend to offer flexibility and slightly lower salaries, in-house developers can offer immediate availability and quick response times.

If you are still debating your pick between these 2 approaches, this blog can serve as a quick fix.

Besides these 2 hiring routes, the Gig economy has also gained widespread prominence and freelancers have begun to have considerable dominance in the marketplace. If you are looking for short-term or project-specific assistance while keeping a hold on your budget, freelancers could be an ideal pick. Depending on project complexity, experience, and skill level, the rate of PHP freelancers can typically vary. Let’s see the breakdown based on experience level:

  • Entry-level freelancers with 0-2 years of experience command anywhere between $20-$40 per hour.
  • Freelancers with mid-level expertise of 2-5 years can charge in the range of $40-$80 hourly.
  • Senior freelancers who have 5+ years of experience in PHP can charge $80 or more per hour, going as high as $150 hourly.

These PHP developer interview questions are designed for assessing technical proficiency, framework-specific knowledge, and behavioral capabilities of the developers.
