Going by the body text of your question, I guess 4 years. I first started coding web pages with free hosts like Geocities and Angelfire. 2 years later I dove into PHP which compared to HMTL and CSS looked very foreign to me at the time, having no prior experience with procedural languages. However, I have gotten accustomed to that as well, to build websites with dynamically generated web pages, and query strings and forms to fetch data from databases. This was still non-OOP and without frameworks, but it worked for me. My first ever paid web development job was for a freelance client who needed a simple intranet application for private auctions. He seemed fine with my knowledge of PHP and MySQL, and was able to get the job fine in the entire month that it took.
