PHP Programmer Requirements-Skill Requirements

As a qualified PHPer, the first thing is the love for PHP. As the saying goes: "Do one thing well." To do things, you must first understand him, and then love him."

PHP is a wonderful development language. You no longer need to hesitate to define the type of a variable. PHP will automatically determine it; you don't need to hesitate to define the type of a variable. If you need to declare N number of functions to get a form data, leave everything to PHP!

With only a good development language but no knowledge of databases, we are still unable to make progress!

Fortunately, we have the same open source, compact MYSQL! For a web developer, we can't just know (fill/delete/modify/check-insert/delete/update/select). In order to make our website run faster and smoother, we also need to know the optimization of mysql.

Yes! At this time, views and indexes will help you achieve the results you want.

2, Apache

3, Javascript

"Back-end languages ​​are all competing, but front-end languages ​​are the only one!" Yes, this is a true reflection of Javascript's status as a front-end language! If you want your website to have gorgeous visual effects, you can't do it without Javascript; if you want your website to have a good customer experience, you can't do it without Ajax! Even though sometimes Javascript frameworks such as YUI and JQuery can help us improve efficiency, their foundation is still Javascript!

4. Algorithms and data structures
