Essential abilities to become an excellent PHP developer_PHP Tutorial

PHP is an efficient network programming language. Due to its advantages of flexible writing and fast running, it has quickly become the preferred language of Web programmers. So how can you become an excellent PHP developer?

It is not easy to become a PHP programming master. It is not as many people imagine, as long as you can quickly write a few simple codes to solve the problem. A complicated problem is for PHP programming masters. Real PHP masters need to consider many other issues. The following three guidelines are the guidelines that a mature PHP programmer should first follow in programming.

　◆Laziness is golden

　◆Write beautiful code

　◆Pursue the speed of the program, not the speed of the program The speed of programming

Laziness is golden

Be a lazy programmer? This idea is so weird! Because the busiest people in the world may be computer programmers. But it is precisely because programmers are too busy that they should learn to be lazy when programming. For a programmer, there are two lazy ways:

One is to boldly use other people’s ready-made program codes and integrate these codes into your own programs or projects. The second is to write some useful codes to build a function library, which can be easily used when writing programs in the future. This saves a lot of repetitive work and naturally makes you less lazy. These two lazy methods are very suitable for PHP programmers.

First of all, PHP is a language that was born and grown in a free and open environment. There are thousands of programmers around the world who have been constantly striving for the perfection of PHP, and they are also willing to share their ingenuity and the code they write with others. You can find a lot of excellent program code every day from some PHP websites, mailing lists, and news groups.

In this way, I am not encouraging you to wait all day for others to write code for you, but you can "stand on the shoulders of great men", fully carry forward the "use doctrine", and intelligently apply other people's Program code can save you a lot of time. Secondly, in PHP, you can easily build your own function library, which can save you a lot of trouble when writing programs in the future.

The author below introduces several common functions to you. Some of these functions come from some open source projects on the Internet, and some are selected from the mailing list. If you can add them to your own library, sooner or later you will find yourself benefiting from them.

　　1. General database processing functions

Compared with other CGI functions, one of the advantages of PHP is that it has very powerful database processing capabilities. However, in PHP, some specific functions are used to handle different databases, and there is a lack of general database processing functions. This greatly reduces the portability of program code, which also brings a lot of inconvenience to beginner programming friends.

On the Internet, many programmers have solved this problem by encapsulating classes. They wrote unified functions to handle any popular database - whether it is Mysql, which is popular in the Linux world, or SqlServer, which is widely popular on Windows platforms.

Personally, the author likes to use these functions very much, because you can directly use some simple functions such as "query" and "next_record" without having to consider the complexity of database connections and database handles. There is no need to consider what kind of database is used. If you need these functions, you can get them by visiting the following URLs:
