Become a PHP expert and learn to use PHP programming with laziness

PHP is an efficient network programming language. due to its advantages in mobile programming and fast running, Agility has become the preferred language for Web programmers. A recent authoritative survey showed that 31.6% of websites now use PHP as an important server.

However, it is not easy to become a PHP programming expert. As many people think, as long as they can quickly write a few simple codes to solve a complicated title, they are PHP programmers, real PHP experts also need to consider other titles. The following three principles should be followed by a mature PHP programmer in programming.

1. laziness is gold
2. write beautiful code
3. seek the speed of the program, not the speed of programming

　　1. laziness is gold

Is it an idle programmer? This idea is amazing! The busiest people in the world may be computer programmers. But it is because programmers are too busy that they should learn to be lazy during programming.

For a programmer, there are two ways of laziness: first, brave application of ready-made others' program code to integrate the code into your own program or project. The second is to write some useful code to create a function library, which can be easily written in the future, saving a lot of repetitive work. Naturally, you can be idle.

Both of these methods are very suitable for PHP programmers.

First, PHP is a language born and grown up in a free and open environment. There are thousands of programmers around the world who have been constantly striving for PHP perfection and are willing to share their talents and code with others. Every day, you can create a large number of excellent program codes from some PHP websites, email lists, and message groups. In this way, I do not encourage you to wait all day for others to write code for you, but you can "stand on the shoulders of great people" and fully carry forward "ism ", intelligent use of others' program code can save you a lot of time. Second, in PHP, you can easily create your own function library, which saves you a lot of trouble in programming later.

Below I will introduce several common functions for you. some of these functions come from some open source projects on the Internet, and some are selected from the mail list. If you can add them to your own function library, sooner or later you will invent yourself and enjoy unlimited benefits.

1. common database processing functions

Compared with other CGI functions, one of the strengths of PHP is its strong ability to process databases. However, in PHP, some specific functions are applied to different databases for special processing, and there is a lack of common database processing functions. This greatly reduces the portability of program code, which also brings a lot of inconvenience to beginners.

On the Internet, many programmers solve this title by encapsulating classes. They have compiled the same function to deal with any popular database-Mysql, which is popular in the Linux world, or SqlServer, which is widely used on Windows platforms. In my personal opinion, I am very fond of using these functions, because some simple functions such as 'query' and 'Next _ record 'can be applied directly, you do not need to consider the complex things such as database connection and database handle, and do not need to consider what type of database is used.
