I'm a PHP developer with about 5 years of experience, and I'm curious to know how the salary of a PHP developer changes as they gain more years of experience beyond the initial stages. I'm currently working in a mid-sized software development company and have been noticing some salary discrepancies among my peers who have been in the industry for different lengths of time.
I'm interested to know if there is a general pattern or trend in terms of salary growth for PHP developers. Does the salary tend to increase significantly with more experience, or does it plateau after a certain point? Are there specific milestones in terms of years of experience that are important for salary negotiations?
Additionally, I would appreciate any insights into other factors that might affect salary growth, such as additional skills or certifications, the size and location of the company, or specialization within PHP development.
Thank you in advance for sharing your knowledge and experiences!
