How To Install VSCode For PHP On Ubuntu

It provides steps required to install Visual Studio Code or VSCode for PHP development on Ubuntu 18.04 LTS and getting started with PHP development using the Hello World project.

Visual Studio Code or VSCode is a cross-platform, lightweight editor and became popular in a very short span. It provides support for several programming languages. It also supports plugin development and there are several community-driven plugins available for it.

In this tutorial, we will discuss how to install and prepare Visual Studio Code or VSCode for PHP development on the popular Linux distribution i.e. Ubuntu. It provides several features for PHP development including IntelliSense, Syntax Highlighting, Bracket Matching, Snippets, Linting, etc. This tutorial provides all the steps required to install VSCode on Ubuntu 18.04 LTS, though the steps should be similar for other Linux systems.

It assumes that PHP is already installed on the system. You may also be interested in How To Install LAMP and How To Install PHP 7 On Ubuntu 18.04 LTS.

Step 1 — Download Visual Studio Code

We can download Visual Studio from the official download page. It provides options for Ubuntu as shown in Fig 1.

Click on the .deb Download Button to start the download. You can also download the gz file to install it directly without using the deb package. This tutorial provides steps to install VSCode using the Debian package.

Step 2 — Install Visual Studio Code

In this step, we will install the Visual Studio Code downloaded by us in the previous step. Double click the installer to execute it. It will show the installer screen as shown in Fig 2.

Click on the Install Button to start installing VSCode. It will show installation progress as shown in Fig 3.

After successful installation, it will show the final screen as shown in Fig 4.

Now close the screen to complete the installation. Click on the Show Applications icon at the bottom right corner of Ubuntu 18.04. It should show Visual Studio Code as shown in Fig 5.

You may add it to your Favorite Apps or create a desktop shortcut icon based on your preferences. Launch VSCode to start coding in PHP. It will show the welcome screen as shown in Fig 6.

Step 3 — Marketplace

You can see all the available plugins on the Marketplace dedicated for Visual Studio Code. Type php in the search box and click on the Search Button. The results should be similar to one as shown in Fig 7.

We can also browse the available extensions within the IDE by clicking on View -> Extensions or press Ctrl + Shift + x. Enter php on the Search Box and hit Enter Key. It will show the same extensions list within the IDE as we saw on the Marketplace Page as shown in Fig 8.

Step 4 — Install Extensions

We will install the most important extensions as part of this tutorial. Also, make sure that you are using the most recent version of PHP. Your system should have at least PHP 7.2 to use the new features available in PHP 7.

PHP IntelliSense and PHP Debug are the most important extensions that every PHP developer must install for Visual Studio Code or VSCode. The other extensions can be installed based on the requirements. Install both the extensions as shown in Fig 9 and Fig 10. You may also install the JavaScript extension similar to PHP.

Step 5 — Getting started with PHP — Hello World

In this section, we will create our Hello World project i.e. HelloPHP project and write and execute the first script using Visual Studio Code.

Click on File -> Open Folder or press Cntrl + K and Cntrl + O to open the File Chooser to select the project folder. It will open the selected folder as highlighted in Fig 11.

Now click on the New File Icon as highlighted in Fig 12.

Enter the file name as index.php and hit the Enter Key. It will create the PHP file as shown in Fig 13.

Update the file and write the first program to print Hello PHP as shown in Fig 14.

Now right-click the file and choose the option Open In Terminal. It will open the terminal within the editor as shown in Fig 15.

Notes: You can also use the Code Runner extension to execute the code.

We can execute the PHP file on the terminal as we do on command prompt by giving the PHP command as highlighted in Fig 16. It also shows the output on the terminal.

Other option to execute the program is to install the Code Runner Extension as shown below.

Now execute the program and view the output as shown in Fig 17 and 18.

This is how we can install Visual Studio Code for PHP development on Ubuntu. We have also written our first hello world program and executed it within the editor using the terminal.

Coding php in linux

1. Синтаксис

Код в PHP заключается в открывающий теги. Согласно стандарту кодирования PSR-12, закрывающий тег должен быть опущен в файлах, содержащих только код PHP . В конце строки ставят разделитель строк – точку с запятой ; . Если забыть поставить разделитель, то следующая строка кода соединится с предыдущей и интерпретатор PHP выдаст ошибку.

Выведем на экран строку Hello World (заключена в кавычки) с помощью команды echo :

Оператор if выполняет код, если выполняется условие. В противном случае выполняется код после else, который переводится, как «иначе», «в другом случае».

Оператор while выполняет код до тех пор, пока значение условия не станет ложным.

Когда нам известно количество итераций, вместо цикла while лучше использовать цикл for .

Массивы – упорядоченная коллекция элементов с доступом по индексу или ключу. Индексный массив создается двумя способами:

Если мы получили ошибку 404, значит сервер запущен.

XAMPP

Скачаем и установим XAMPP . В папке C:\xampp\htdocs\ создадим папку нашей странички page . Запустим веб-сервер Apache, кликнув по кнопке Start . Узнаем версию PHP, введя в консоли (Shell) команду php -v .

Проверим, запущен ли сервер, перейдя по адресу http://localhost/ . Если появилось приветственное сообщение, значит сервер запущен.

14. Собираем страничку

Теперь создадим несколько PHP-файлов, из которых соберем страничку. Перейдем в папку page и создадим четыре файла: index.php , header.php , body.php , footer.php .

Структура простого HTML-документа выглядит следующим образом:

Литература

• Робин Никсон. Создаем динамические веб-сайты с помощью PHP, MySQL, JavaScript, CSS и HTML5;
• Котеров, Симдянов. PHP 7;
• Веллинг, Томсон. Разработка веб-приложений с помощью PHP и MySQL;
