With 80% of global websites being built using PHP, 长期使用的后端编程语言的生态系统继续蓬勃发展. 这意味着基于php的技术在如何增加价值方面继续发展, 从初创公司到大企业都在继续利用它们, 那是新的和有经验的 developers alike continue to choose it for their careers.
PHP可以用于开发几乎所有可以在web上找到的软件类型, like custom-built websites of any size, WordPress的网站, APIs, 后端microservices, and 性能关键型服务. 如果您需要开发这样的产品，应该考虑PHP专家.
PHP编码人员通常通过利用PHP众多良好支持的开发框架之一的强大功能而使业务受益, like Laravel, Symfony, or Laminas(原Zend Framework). Frameworks provide PHP developers with a common structure so they don’t have to spend time building and organizing basic features like routing, 数据库连接, 从头开始配置. If your project already uses a PHP framework, hiring PHP specialists is a natural fit because they will be able to efficiently leverage your current development environment to start creating new capabilities.

PHP是一种简单而快速的脚本语言，拥有非常大的社区. With PHP’s huge popularity, it’s easy and inexpensive to find hosting to run PHP applications. 使用像Laravel这样的框架, Phalcon, CakePHP, Yii, and CodeIgniter, PHP has become a very suitable language for building large web applications as well. Whether your company is building a simple website, 大型单片应用程序, or a microservice, PHP and its many frameworks can be a very good choice.
Also, 值得一提的是流行的基于php的软件，比如WordPress, Laravel, Drupal, MediaWiki使得构建特定的应用程序(如CMS系统)非常经济高效且快速, blog platforms, 或者电子商务网站, among others.

Nearly a fifth of professional developers surveyed in 2023 used PHP, placing it among the top 10 programming languages. And PHP programmers are prolific: Statistically, 近80%的网站 使用基于php的后端，在很大程度上由 巨大的受欢迎程度 of private installations of WordPress—whose core and customizations are written using PHP.
Demand for PHP developers for hire remains steady as the language continues to evolve: Codebases using PHP need to be maintained in order to work with currently supported and secure PHP versions. 有这么大的子市场, 公司很难吸引到顶尖的开发者, 而更难以有效地评估大量的候选人. 本指南将帮助你做到这两点, 通过概述需要注意的子技能, 面试中要问的问题, and points to cover in a winning job description.
Before exploring distinguishing attributes, it helps to first answer the question, “PHP开发人员是做什么的??PHP开发人员的职责包括编写, testing, 并维护服务器端web应用程序的源代码. 这些应用程序既可以使用纯PHP开发，也可以利用各种PHP框架开发, like Laravel, Symfony, and CodeIgniter or content management systems (CMS), like WordPress, Drupal, and Joomla.
Deep skills with a particular PHP framework allow a programmer to multiply their productivity by avoiding the reinvention of the wheel. 但是熟悉多个框架可以让PHP专家 做出更明智的选择 就绿地项目而言.
最好的PHP程序员确保应用程序的性能和安全性， avoidmistakes，并编写遵循深思熟虑的软件开发原则的代码. They will have experience with common back-end tasks like connecting to databases and be capable of handling basic DevOps responsibilities like creating and configuring environments. 他们还将知道如何满足谨慎级别的安全标准，以避免不必要的业务风险.
上述的一些方面可以根据候选人的履历和后续讨论来评估. However, 许多公司选择直接评估编程能力, 要么是现场编程面试，要么是带回家的评估.
这两种策略都增加了谈判双方的时间要求, although companies can outsource these evaluations, 特别是现场编程面试. But without some kind of code quality evaluation, 公司不能自己判断应聘者一旦被录用后所能写出的PHP代码的质量. One alternative for candidates who happen to be open-source contributors is for companies to directly evaluate their code contributions, 但要用这种策略产生一致的参数要困难得多.
The consequences of missing this step may involve additional training expenses or a lost onboarding investment—assuming a company has a functioning quality assurance system that would catch newcomers’ mistakes before they did any serious harm to the product.
How can you identify the ideal PHP Developer for you?
Hiring managers who understand the most common types of PHP projects are better positioned to spot appropriate candidates and match them to their business needs. Whether it’s within the scope of customizing a CMS system or other type of website, PHP experts are most commonly sought to:
建立一个动态站点或添加动态组件，如356平台, search, user registration, authentication, a shopping cart, and more.
Integrate an existing site with other systems such as third-party payment processing APIs.
Troubleshoot and optimize poorly performing websites.
实现多因素身份验证(MFA)等高级安全机制, 彻底的输入物卫生处理, 安全会话管理, and industry-standard encryption protocols.
Assess code for adherence to industry standards, proper structure, and security requirements.
Test code across browsers, devices, and operating systems to ensure seamless functionality.
A preexisting project built upon a PHP framework or platform like WordPress could leverage the skills of a PHP specialist. In particular, experience with Symfony and Laravel are helpful because Symfony is the basis for other popular PHP-based technologies like Drupal, while Laravel has established itself as a fundamental framework for numerous existing products. In addition, Laravel is excellent for rapid prototyping, 而Symfony为长期可伸缩性提供了更稳定的基础. But each PHP-based system has its nuances, 所以，如果你想让应聘者立即投入工作，就有必要了解他们的具体经验水平.
超越框架和平台, there are several related technologies that are strongly relevant when examining the experience of PHP developers for hire:
Relational (SQL) databases such as MySQL and PostgreSQL -虽然不是后端存储数据的唯一方法, SQL is a well-established standard and still wholly appropriate for a litany of use cases. 除非你的技术栈特别使用像MongoDB这样的NoSQL数据库, 在雇佣PHP专家时，强大的SQL技能是必须的. 如果他们的经验与您的项目使用的特定数据库一致，这将特别有帮助.
REST APIs and web servers – Your project may not implement its own REST API—perhaps using a GraphQL-based API instead—but chances are your project’s back end will eventually need to integrate with a third-party REST API. To that end, it’s worth hiring a PHP engineer who knows a few tricks about optimizing async calls to REST APIs and handling their errors appropriately.
面向对象编程 (OOP) and 模型-视图-控制器 (MVC) architecture -这些广泛使用的编码方法使代码更具可读性、模块化和可维护性. PHP developers not well-versed in them may take longer to familiarize themselves with your project’s codebase and may struggle to create code others can collaborate on efficiently, lowering your ROI. This is crucial not only on large-scale projects, 但也适用于较小的项目，因为只有当它们具有内聚的体系结构方法时，它们才能实质性地发展.
Unit testing 即使是最基本的软件也能从这种自动化测试技术中获益. 拥有一套单元测试意味着可以指望特定的代码模块继续正常工作, even when seemingly unrelated code is changed. 坚持使用认真对待单元测试的PHP专家:没有它, 开发者很容易在恶性循环中浪费时间, 修复一个紧急的bug，导致另一个bug重新出现.
When employing skilled PHP developers, 重要的是，他们拥有技术技能和软技能的正确组合. The latter are important because PHP experts usually work on complex core system features where the interaction with other team members is essential. Furthermore, 组织技能——包括熟练使用必不可少的协作和源代码控制工具，如 Git-对于任何PHP开发角色都应该被认为是给定的.
Before looking to hire PHP developers, it is best to define the scope of your project. Writing down the specifics of your project will provide clarity on the skills gap you face, the gaps you anticipate down the road, 是专注于雇佣一名全职员工，还是选择一名灵活的自由职业者.
After defining your project and any skills gap, you next task is to create a job post. It’s helpful to use a template for this, 包括你公司最相关和最吸引人的细节, team, and project.
When interviewing PHP engineers, open-ended questions can be used to spark further discussion:
What PHP frameworks have you worked with, and what has your experience with each been like?
The isset function is used to determine if a variable exists and has a non-null value, returning true in that case. In contrast, the empty 函数检查变量是否为空，返回 true 如果变量为空(i.e., not set, false, 0, an empty string, an empty array, or null). While isset checks for existence and a non-null value, empty 特别关注空，包括空值.
使用预处理语句或参数化查询来防止SQL注入漏洞. 预处理语句将SQL代码与用户输入分开, 消除了注入恶意代码的可能性. 通过将输入值绑定到SQL语句中的占位符, the database engine can distinguish between the actual SQL code and user-supplied data, 有效防止任何未经授权的SQL操作.
在PHP中，可以使用错误处理机制来处理错误和异常. 一种常见的方法是使用try-catch块捕获异常并优雅地处理错误. 通过将可能生成异常或错误的代码包装在try块中, you can catch the specific exception or error type and provide appropriate error handling or recovery logic in the corresponding catch blocks.
两者的区别是什么 include and require in PHP?
Both include and require are used to include and evaluate external PHP files. 它们之间的主要区别在于它们如何处理错误. The include 语句包含一个文件，并继续执行脚本，即使没有找到该文件或未包含该文件, 导致警告. In contrast, the require 语句包含一个文件，如果没有找到该文件或未能包含该文件，则使用致命错误停止脚本执行. In situations where the included file is essential for the script’s functionality, require 通常更倾向于确保脚本在没有它的情况下不会继续.
PHP provides built-in support for handling sessions, 哪一个允许开发人员跨同一用户的多个请求持久化数据. 初始化和使用会话的过程包括以下步骤:
