What skills do beginners need to learn php?

Let me talk about several types of programmers I often meet in my daily development.

Most people who do JAVA development have strong background logic ability and know a lot of things, but few people are familiar with the front-end things, especially css and js. Some people can't do it at all, but JAVA development is still proper.

Do front-end development, front-end skills are basically very good, according to the design drawings can be perfectly implemented with code, can make a lot of dazzling special effects. But the back-end dynamic language basically doesn't.

Database operation and maintenance, they understand the collocation of various environments. PHP，JAVA。 All kinds of server monitor, but I envy people who can develop, and can do a complete website well.

Doing PHP development, they know PHP, but that's useless, because without a database, PHP is equivalent to a useless language. Therefore, we should also know that the database is generally Mysql, and the database can extract data to the foreground. But PHP is generally suitable for writing client-oriented programs. It is useless to spit a bunch of messy data to the foreground. You must organize HTML for them. Users are all visual animals, and the ugly boss of this website will not let you go, so you need to know CSS and Javascript to make some special effects. After doing this, you need to know the server. You have to run this program for users to see, so you have to know the server.

Nowadays, PHP and Java are commonly used in web development. The advantage of PHP over Java is that there are many open source softwares in PHP, which are really numerous. This is an advantage over Java. So PHP development can be simple or complex.

Normal PHP development is generally divided into two types, using the existing framework development and using the existing system transformation. The purpose of frame development is to decorate rough houses. The purpose of system transformation is to finely decorate the house that has been decorated. Want to quickly, of course, is to choose the open source CMS system to change, most of the functions are written, as long as you know the front end, you can do great.

Common open source PHP systems in China include Imperial CMS, PHPCMS and Dreamweaver CMS. Blogs, such as wordpress, are used by people all over the world, as well as z-blog and so on. Of course, it takes time to learn these open source systems. So you can also use the framework as the basic development, of course, you need some basic skills. ThinkPHP is the most widely used in China, and employers use it the most. Then, for example, Codeigniter or YII is commonly used. ThinkPHP and Codeigniter are more suitable for beginners.

There is also Mysql, which will be used when learning PHP, so you must know some basic syntax, such as adding, deleting, modifying, searching, and others, such as creating tables and libraries. Let PHPmyadmin help you realize it, and the company won't ask you to create it with code.

That's it. Get a job quickly. A job of about 6000 yuan is suitable for second-tier cities. I know nothing about the front end. Just go to the company and hug the thigh of the front-end sister paper. I'll talk to the front-end sister paper and ask her to help you solve it.

Okay, this is advanced. PHP is a background language. If you want to be a full-stack engineer, you must learn the front-end knowledge, such as the basic HTML+CSS layout and the recently popular H5 development. The development of mobile phone web version still needs to understand the basis of responsive development. If you don't want to dig deep, you can also use the front-end framework to speed up development. The interface is ugly, but the effect is good. For example, Bootstrap is used all over the world. For example, amaze (sister paper UI) in China is a very good framework, and the development of front-end response is also leveraged.

Continue to push forward, these have been done, and local development will fly. Ok, now you need to put the project on the server, so you need to know something about the server. PHP language generally runs on linux system, such as centos or ubuntu, which is very easy to use. Simply learn the commonly used instructions and then add Baidu. Basically, it takes several days to build a web server. Have you ever heard of lamp? It is Linux+Apache+mysql+PHP. This is the so-called golden combination. To understand everything inside, you are basically a very good programmer.

Basically, at this step, you can put the whole project online perfectly. If you want to continue learning, you need to know some interfaces and third-party components. Learn about WeChat payment, Alipay payment interface, Weibo open platform, QQ login and so on.

Later, you will naturally pay attention to some aspects of web security and optimization, such as database optimization, sql injection, caching, high generate and so on. Then we can talk about hardware.

I won't say the rest, because at this level you already know what you should know. The salary has exceeded 10,000 yuan, specifically tens of thousands, depending on your eloquence and packaging during the interview ~
