PHP Programmer:

In a narrow sense, a PHP programmer is a programmer who uses PHP as a development language. But often a programmer is not just limited to a certain development language, or divided by a certain development language. However, in order to improve development efficiency, the division of labor among technology companies is becoming increasingly clear, and it is rare for a programmer to develop in multiple languages ​​at the same time.

Market demand:

1. Online store systems shopex, ecshop and other well-known free independent online store systems are all developed in PHP language. PHP MYSQL has also become the first choice for online shopping systems because of keywords such as "open source and speed". At present, shopex, the largest online store provider in China, is expanding rapidly and needs a large number of PHP programmers.

2. Open source forum has produced many open source systems because of the open source of PHP. The once popular Discuz! forum system is a good proof. Compared with online store systems, there is not much demand for PHP programmers doing forum development.

3. Secondary development is basically based on secondary development of open source systems such as shopex, ecshop, Discuz!, etc. Most of these companies are small and medium-sized companies. In addition to PHP, programmers are also required to know some DIV/CSS, javascript/JQuery, Ajax and other technologies. In order to maximize cost savings.

Skill requirements:

As a qualified PHPer, the first thing is the love for PHP. As the saying goes: "To do something well, you must first understand it, and then love it." 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 do not need to declare N many functions when getting a form data, everything is left to PHP !

1. MYSQL

Yes, if we only have a good development language but do not understand the database, we will still be unable to make progress! Fortunately, we have the same open source, compact MYSQL! You know, 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 mysql Optimization. That's right! At this time, views and indexes will help you achieve the results you want.

2. Apache

How can our program run without Apache! At least you need to know some basic configuration information of Apache!

3. Javascript

"Back-end languages ​​compete with each other, and front-end languages ​​are the only ones that dominate!" Yes, this is a true reflection of Javascript's status as a front-end language! If your website wants to have gorgeous visual effects, you can't do without Javascript; if your website wants to have a good customer experience, you can't do without Ajax! Even though sometimes Javascript frameworks such as YUI and JQuery can help us improve efficiency, don't forget that their foundation is Javascript!

4. Algorithm

In fact, according to common sense, algorithms are the "soul" of programmers. A qualified programmer's first requirement is often a strong foundation in algorithms. However, web development has overturned this tradition. Since PHP is primarily used for web development, this skill is less needed. So, many times, people are discussing whether web developers cannot be counted as real programmers?
