What are the requirements for self-study PHP from scratch?

How long does it take to learn PHP by yourself with zero basic knowledge? This is a question that self-taught people are more concerned about. PHP is almost the easiest popular language to get started with. Once you are familiar with the syntax and commonly used functions, you can do some simple web development. For example, simple tasks such as writing a guest message board, sending emails, etc. To reach this level, it usually takes a few days to a month to learn PHP by yourself.

Before you decide to enter the world of PHP programming, you need to do some self-assessment. The following evaluation conditions depend on whether you have the ability to teach yourself PHP programming.

1. I am very satisfied with my current job. No need to change jobs.

2. Have a deep interest in PHP.

3. Have some programming basics. For example, I have been exposed to languages ​​such as C, java, and PHP.

4. You have strong self-control ability.

5. You have strong self-learning ability.

6. You have strong time management skills.

7. Your English level is able to read English technical documents.

8. You are a person who loves to read.

9. Your inner world is very quiet and is not easily disturbed by other things. For example, if a friend invites you to go fishing, play basketball, billiards, etc., you will remain unmoved. Keep doing programming related things.

If you can do more than five of the above, congratulations, study on your own, you will definitely become a PHP programming expert, believe in yourself.

Summary:

PHP is a C-like language. If you have a "foundation" in C language, it should be easy to get started. But to build a large-scale practical website that can support high traffic, you also need to master many related technologies, such as: database (mysql), cache (memcached/redis/mongod), system calls (files, networks, disks, memory) ), various servers (linux, apache/nginx, sphinx, message queue), and it is best to have a deep understanding of the data structure and algorithm principles involved in the PHP language itself, so that you can write concise, efficient and high-quality code. To reach this level, I personally feel that in addition to theoretical study, it is still difficult to achieve without more than two years of practical development training. Getting started with PHP is easy, but mastering it is not easy, just learn and work hard!
