PHP syntax is similiar to C, So PHP knowledge will help you in long run, you will see advantage of it when you move to its OOP (Object-oriented programming) structure. PHP is easy to learn, And while you learn PHP you will also get knowledge of MySQL for working with database driven projects.

After learning PHP you will see other languages will become easy to learn, you can move to Csharp (C#), which definitely is worth to learn. PHP will open a lot of doors for you for other programming languages.

But remember one thing, If you will just watch the tutorials or read books you are not going to be expert in any programming language, After getting basic knowledge give yourself some challenges, code stuff, if you stuck on some points try to ask on forums, search on google, It's the only best way you will learn.

Good Luck
