PHP, SVN, and Git: A Comprehensive Guide

As a developer, understanding the tools and technologies that streamline the software development process is crucial. In today's blog post, we will delve into the worlds of PHP, SVN, and Git and explore their significance in modern software development.

PHP: The Dynamic Language for Web Development

PHP, also known as Hypertext Preprocessor, is a powerful and versatile server-side scripting language primarily used for developing dynamic web applications. With its simplicity and broad community support, PHP has become one of the most popular choices among web developers.

Version Control Systems: SVN and Git

In collaborative software development, managing various versions of source code is essential. This is where version control systems (VCS) come into play. Two widely adopted VCS options are Subversion (SVN) and Git. Let's explore these tools in more detail:

Subversion (SVN)

SVN is a centralized VCS that tracks changes made to files and directories over time. It's known for its stability and simplicity, making it an ideal choice for small to medium-sized projects. SVN relies on a central repository that all team members can access, allowing for seamless collaboration and version control.

Git: Distributed Version Control at Its Best

Unlike SVN, Git is a distributed VCS that offers a more decentralized approach to version control. With Git, each developer has a local copy of the entire repository, enabling them to work offline and commit changes locally. The distributed nature of Git provides enhanced flexibility and resilience, making it highly regarded in the software development community.

Comparing SVN and Git

When deciding between SVN and Git, it's crucial to consider your project requirements and team dynamics. Here are some notable differences:

Branching and Merging

SVN: Branching and merging in SVN can be complex and time-consuming. Due to its centralized nature, SVN requires a connection to the central repository for performing merges, resulting in potential bottlenecks.

Git: Git excels in branching and merging. Branches are lightweight, allowing developers to create, switch, and merge branches effortlessly. Git's superior merge capabilities and branch management make it a preferred choice for complex projects.

Speed and Performance

SVN: SVN relies heavily on network communication with the central repository, impacting performance, especially during large file operations and version history retrieval.

Git: Git's distributed architecture ensures fast and efficient performance. As most operations are performed locally, Git eliminates the dependence on network connectivity, resulting in swift operations and better productivity.

Community and Ecosystem

SVN: Being one of the oldest version control systems, SVN has a well-established community and excellent integration with various development tools.

Git: Git's popularity has soared in recent years, resulting in a vast and vibrant community. The Git ecosystem provides a plethora of third-party tools, extensions, and integrations that enhance its functionality and adaptability.

Getting Started with PHP, SVN, and Git

Now that we understand the significance of PHP, SVN, and Git, let's discuss how to get started with these tools.

PHP Development Environment

To begin PHP development, you need to set up an appropriate environment. Install PHP, along with a web server such as Apache or Nginx. Additionally, consider utilizing a development framework like Laravel, CodeIgniter, or Symfony, which offer robust features and ease the development process.

Using SVN for Version Control

If you decide to adopt SVN for version control, the first step is setting up and configuring your repository. Choose a reliable SVN server, such as Apache Subversion or VisualSVN Server, and create a repository structure aligning with your project requirements. Next, familiarize yourself with common SVN commands like checkout, commit, update, and branch to efficiently manage your source code versions.

Utilizing Git for Version Control

If you opt for Git, start by initializing a local repository in your project directory using the 'git init' command. Familiarize yourself with Git's core commands, such as 'add', 'commit', 'pull', 'push', and 'merge'. Additionally, explore branching strategies like feature branching, release branching, and hotfix branching, which facilitate a smooth and organized development process.

Conclusion

In a technology-driven world, staying ahead requires leveraging the right tools. PHP, SVN, and Git each play a crucial role in modern software development, offering unique advantages and capabilities. Whether you choose PHP for dynamic web development, SVN for centralized version control, or Git for its distributed functionality, understanding these tools will undoubtedly refine your development workflows and elevate your projects to new heights. Embrace the power of PHP, SVN, and Git, and unlock the true potential of your software development endeavors.

二、大厂用git还是svn?

大厂用git。

# 只用过Git,没用过SVN~

当然从发展来看无疑是Git好了! 你看看最大的两个开源平台GitHub和GitLab就知道了,她们都使用的Git!!!

三、git和svn的作用?

SVN 的主要功能

SVN属于集中化的版本控制系统,有个不太精确的比喻:SVN = 版本控制+ 备份服务器

SVN使用起来有点像是档案仓库的感觉,支持并行读写文件,支持代码的版本化管理,功能包括取出、导入、更新、分支、改名、还原、合并等。

功能有许多我就不一一列了,SVN大都采用图形界面操作,直观,上手快。

Git的主要功能

Git是一个分布式版本控制系统,操作命令包括:clone,pull,push,branch ,merge ,push,rebase,Git擅长的是程序代码的版本化管理。

四、Git跟svn哪个好用点?

# 只用过Git,没用过SVN~

当然从发展来看无疑是Git好了! 你看看最大的两个开源平台GitHub和GitLab就知道了,她们都使用的Git!!!

五、svn 与git哪个入门快?

你好,正常来说,svn上手快,因为SVN大都采用图形界面操作,使用起来有点像是档案仓库的感觉,支持并行读写文件,支持代码的版本化管理。

Git是一个分布式版本控制系统,操作命令包括:clone,pull,push,branch ,merge ,push,rebase,Git擅长的是程序代码的版本化管理,图形界面支持差,使用难度大。不易推广。

六、git对比svn有什么优势?

Subversion是集中式管理的数据仓库

虽然速度快和多副本等git分布式数据仓库显而易见的好处吸引了很多人的喜爱,但在很多情况下,一个集中式的数据仓库却是更合适的。例如,如果你有一些核心代码想只允许部分人能访问,把它放到git里必然是你不希望的。很多的企业都是将它们的代码集中管理的,我猜,所有(重要)政府项目估计都使用的是集中式数据仓库的版本控制系统。

Subversion的理念符合常规思维这是说,很多人(特别是管理者或老板)对版本号有一种习惯的认识,把开发视作一种按时间的线性发展轨迹,这在他们脑子里根深蒂固。并不是找借口,Git的随意性并不是很容易去理解,你也许注意到了,任何一本关于Git的书都会在第一章第一节告诉你要抛弃脑子里所有的传统观念,重新认识。

Subversion只提供一种途径,没有第二选择

SVN是一个版本控制系统,它只提供一种方式做这些,每个人都使用相同的方法。就是这样。这使得你将代码从SVN迁移到其它集中式管理的VCS或从其它集中式管理的VCS迁进来变得很容易。Git并不仅仅是一个版本控制系统——它实际上是一个文件系统,它里面有很多的拓

扑学知识来支持你如何在不同的环境中架设代码仓库——并且没有一个统一的标准。选择一个合适的拓扑结构就成了难题。

其它一些优势:

SVN支持空目录

SVN有更好的Windows平台支持

SVN可以check out/clone一个子树(sub-tree)

SVN支持特权访问控制svn lock,在处理很难合并的文件时非常有用

SVN支持二进制文件,更容易处理大文件(不需要把老版本拷来拷去)

提交文件相对简单,因为没有pull/push操作,本地修改通过svn update自动的执行了同步代码的功能。

------------

七、如何在svn系统中使用git?

1、从服务器上克隆完整的Git仓库(包括代码和版本信息)到单机上。也就是说自己机器上有一个git仓库。这和svn是不同的,svn是没有本地的仓库的。所以git是先提交到本地仓库,然后推送到服务器。而svn是直接提交到服务器。这里说一下几个含义:拉取:将服务器中git仓库的数据拉取到本地git仓库,同时修改(更新)当前分支的文件获取:仅仅将服务器中git仓库的数据拉取到本地git仓库提交:将修改的文件提交到本地git仓库。推送:将本地git仓库上的数据推送到服务器。

2、在自己的机器上根据不同的开发目的,创建分支,修改代码。git和svn的一点不同在于svn是通过目录结构来区分不同的分支的。而git你可以点击切换/检出来切换不同的分支。在svn上右键点击RepositoryBrowser可以看见整个工程的目录结构在git上可以点击版本分支图查看整个工程的分支解构。

3、在单机上自己创建的分支上提交代码。

4、在单机上合并分支。

5、把服务器上最新版的代码fetch下来,然后跟自己的主分支合并。

6、生成补丁(patch),把补丁发送给主开发者。git分支保护:自己并没有权限推送到当前分支:1自己创建一个分支,2将自己创建的分支推送上去,3登录git,发送MergeRequests(合并分支的请求)给相关人员。4通知相关人员,并由相关人员将你的代码合并到主分支

八、如何一起使用Git和SVN?

操作步骤:你需要:1.安装 git 和 git-svn2.创建工作目录:mkdir strigi3.初始化git工作目录:4.找到项目的某个提交 (你可以通过 cia版本控制 去获得). 警告: 命令git-log 会从这个版本开始显示项目的版本历史。

5.执行命令git-svn fetch -rREVISION,REVISION 就是刚才获得的那个版本号。

6.更新工作目录:git-svn rebase,现在你就可以在这个项目中使用git作为版本控制了。要保持工作目录更新,可以执行:git-svn rebase你可以用下面的命令将更改提交到svn服务器:git-svn dcommit通过这种方式,所有的git提交都会“转换”成相应的svn命令。解决git-svn rebase的问题在加入新东西之前,你也许会在同步主开发树的时候体验到一些问题。

实际上,你在执行git-svn rebase之前还必须提交所有的本地修改(使用git-commit命令)。

有时候这并不合理,因为你的更改也许还没有准备好提交(还没有完成、测试或者验证这写代码)。不过别担心,git对此也有一个官方的解决方案,只需下面的步骤:

先把你的改动保存起来,使用命令:git-stash更新工作副本,使用命令:git-svn rebase,这跟平时一样恢复保存起来的改动,使用命令:git-stash apply清除“保存”,使用命令:git-stash clear。第1步之后,所有未提交的改动在工作副本上都看不到了,因而你可以执行rebase命令,不会有任何问题。

九、svn和git的区别是什么?

GIT是分布式的,SVN不是分布式的。

这是GIT和其它非分布式的版本控制系统,例如SVN,CVS等,最核心的区别。

2.GIT把内容按元数据方式存储,而SVN是按文件。

3.GIT分支和SVN的分支不同:

分支在SVN中一点不特别,就是版本库中的另外的一个目录。

GIT的分支却是相当的简单和有趣。你可以从同一个工作目录下快速的在几个分支间切换。

4.GIT没有一个全局的版本号,而SVN有。

目前为止这是跟SVN相比GIT缺少的最大的一个特征。

5.GIT的内容完整性要优于SVN。

GIT的内容存储使用的是SHA-1哈希算法。这能确保代码内容的完整性,确保在遇到磁盘故障和网络问题时降低对版本库的破坏。

十、什么是禅道?

禅道,一般指僧侣所修之道。

亦特指禅定之道。

佛家证入"定"的方法之一就是禅。

宋 严羽《沧浪诗话·诗辨》:“大抵禅道惟在妙悟,诗道亦在妙悟。
