如何在2022年成为PHP开发人员

什么是PHP？

PHP是一种服务器端编程语言，主要用于创建网站和Web应用程序。这是一种与HTML一起使用的脚本语言，使PHP开发人员可以简单地创建动态网页。这是open source并免费使用。

phpis one of the most widely used server-side programming languages for creating websites. It is the language of choice for Wikipedia, Facebook, WordPress, and more.

Is PHP still relevant today?

PHP已经存在自1995年以来,这是一个relatively long time for web technology. However, it has gone over many changes, making the version we use today almost indistinguishable from the early versions. Nonetheless, PHP is as popular as ever. It is a secure, performant, easy-to-use, and cost-efficient way to develop a website or web application.

PHP开发人员做什么？

A PHP web developer is responsible for writing the web server code that supports the front end of a web application (although a完整的堆栈开发人员may also be a PHP developer). PHP developers develop code to connect to a database, call a third-party API, and other web services. They support the front-end developers by giving them a way to store data and interface with other server-side technologies.

这是possible to build anything from simple contact pages to complete browser-based single-page applications that interface with client-sideJavaScriptto provide a rich user experience.

除编码外，PHP开发人员还可以享受其他角色：

• 研究现有软件包to see if they can be leveraged instead of writing code from scratch.
• Database design and administration, particularly when related directly to the PHP application that’s under development.
• Automated testing of the PHP code using automated unit testing tools like PHPUnit.
• Web application performance analysis and optimizing an application for the best user experience.

Why should I become a PHP developer?

作为脚本语言，PHP不需要在运行它之前进行处理或编译，并且您不需要任何特殊的软件即可使用它。您需要的只是代码编辑器。几乎所有便宜的共享托管软件包都已经包括PHP，因此比以往任何时候都更容易，更快地运行。

Once you’ve learned PHP, there are many popular frameworks and applications built on top of it, such asLaravel和WordPress，这使得构建应用程序甚至更加容易。

我需要什么技能来学习PHP？

除了语言本身外，良好的PHP开发人员还需要其他几种技能才能成为合格的开发人员。例如：

• HTML的知识。phpis primarily used to generate HTML for viewing in a browser. Although the responsibility for rendering user interfaces could fall to front-end developers, often this can also be something the PHP developer deals with. So, knowing how a web interface gets developed in the browser is something most PHP developers are at least familiar with at a basic level.
• Knowledge of client-side JavaScript。Most websites and web applications that provide a rich user experience use JavaScript in the browser to provide this. The PHP developer needs to know if a request for a page is coming from a regular browser request (e.g., submitting a form or clicking on a link) or an Ajax request coming from JavaScript.
• 网络开发betwayapp下载安装框架。Developing in plain PHP is certainly possible, but in order to speed development, most PHP developers will be familiar with a web development framework. These frameworks help developers write code more quickly, resulting in more secure and more maintainable code.
• 对数据库的理解。phpand MySQL are frequently used together. While it’s not strictly required, a programmer should understand the basics of databases.

这是PHP如何使用非常常见的用例：联系表格的一个示例。在联系表中，您需要验证电子邮件地址以确保其有效。在PHP中，有几种方法可以通过对格式进行简单验证到与第三方API的接口到检查是否实际存在。

How do I learn PHP?

您可以很快购买PHP。这是学习软件开发的最简单方法之一。betwayapp下载安装学习它的最佳方法之一是与讲师进行编码。借助Udemy的初学者课程的PHP，您将学习创建一个简单的内容管理系统，并与讲师一起编码。

It’s important to put what you learn into practice. As with most things, the more experience you get with something, the more comfortable you’ll be with it, and the better you’ll get as a PHP developer. PHP is so simple to start learning that you can begin coding anything you like. You could create a small personal project, then move on to more elaborate projects as your confidence increases.

There are also hundreds of thousands of open-source projects based on PHP, from one of the biggest,WordPress, to many popular projects in use worldwide. Check out the list of使用PHP的GitHub上的开源存储库。有了它，您可以通过榜样从世界各地的经验丰富的PHP开发人员那里学习。现有的PHP Web应用程序和软件包几乎可以想到您可以想到的任何应用程序，其中许多具有干净的，有记录的源代码，您可以从编程实践中获得很多收益。

因此，开始小，创建一些纯代码的东西，然后在您更熟悉该语言时努力进行更动态的编程。

我将拥有什么工作前景？

作为PHP开发人员的工作可以使您在计算机科学工作市场中受到人们的追捧。由于PHP的使用非常普遍，因此需求PHP开发人员。具有PHP技能的网络开发人员有很多机会。这只会随着您获得更多年的经验而增长。在2021年，结束了5,500,000 php开发人员worldwide.

此外permanent positions, there are also many opportunities available for freelance work. You only have to look at freelance sites like上班orFreelancerto see the myriad projects available. To ensure you’re fully prepped for these opportunities, reviewPHP面试问题。

Summary

没有更好的时间学习PHP。今天的PHP是一种强大但易于使用的网络开发语言，可以为世界网站的很大一部分提供动力。betwayapp下载安装成为PHP开发人员将为您提供为无需任何目的开发性能的Web应用程序所需的技能。
