If you need PHP homework help, you have two options. The first one is to get assistance from the experts who work on helpful services. The second one is using sandboxes. Sandboxes are an isolated space in online code editors. Their peculiarity is that you can make a page or write a program and immediately see the result of the work. In the sandbox, you can write a piece of code or lead an entire project. Some of these services allow teamwork: several people work on one task at once.
Sandboxes began to appear en masse in 2010–2013. Now some of these services are moving away from the usual understanding of the sandbox as a place for coding and are developing as a community of web developers. Groups of users are formed within the service. You can chat on Discord, post works in the gallery, and subscribe to your favorite developers and designers.
What are sandboxes for?
The main purpose of sandboxes is to give the user a comfortable and safe place to develop. Here you can learn to code and complete work tasks. The main thing is to remember that on some services, access to projects is open, so others can see your work.
Sandbox code can be added to Stack Overflow, and their analogues. This allows the developer to show their work to other users to ask for help or advice. Also, you can help someone by explaining the solution to the problem.
Some online editors have gone beyond the standard sandboxes and created feeds with trends and examples of work. These include Codepen and Plunker. On these resources, you can see the implementation of modern layout and styling, trend animation, as well as examples of programs from other users. All code is open-source, so you can get inspiration and figure out how problems were solved. Online editors also allow you to immediately see both the structure of the code and its rendering in the browser. Therefore, links to your best work can be added not only to the trend feed but also to the portfolio.
One of the features of CodePen is the Trends section. This is a feed with the work of other developers: layout, animation, programs. Here you can get inspiration, study the implementation, add your favorite works to your templates, and subscribe to other users.
JSFiddle is a sandbox with functionality similar to CodePen. Here you can also configure the editor, enable a validator for code validation, and select languages and preprocessors. And most importantly, JSFiddle offers a large selection of libraries and frameworks.
JSFiddle does not have a blog with interesting works, but it is convenient to use it for collaboration with other developers in real time.
Plunker is like a standard code editor with a preview window added. To get started, you first need to choose a library/framework: Angular, React.js, AngularJS, or Preact, or stay on VanillaJS. After that, the code editor will open, in which you can connect libraries and install npm packages. Style preprocessors can be customized too, although this can be a daunting task for beginners.
These sandboxes will help you not only with PHP homework but with assignments in other languages. Choose the one that suits you the best.
