Your first PHP-enabled page
Create a file named hello.php and put it in your web server’s root directory ( DOCUMENT_ROOT ) with the following content:
Example #1 Our first PHP script: hello.php
Use your browser to access the file with your web server’s URL, ending with the /hello.php file reference. When developing locally this URL will be something like http://localhost/hello.php or http://127.0.0.1/hello.php but this depends on the web server’s configuration. If everything is configured correctly, this file will be parsed by PHP and the following output will be sent to your browser:
This program is extremely simple and you really did not need to use PHP to create a page like this. All it does is display: Hello World using the PHP echo statement. Note that the file does not need to be executable or special in any way. The server finds out that this file needs to be interpreted by PHP because you used the «.php» extension, which the server is configured to pass on to PHP. Think of this as a normal HTML file which happens to have a set of special tags available to you that do a lot of interesting things.
If you tried this example and it did not output anything, it prompted for download, or you see the whole file as text, chances are that the server you are on does not have PHP enabled, or is not configured properly. Ask your administrator to enable it for you using the Installation chapter of the manual. If you are developing locally, also read the installation chapter to make sure everything is configured properly. Make sure that you access the file via http with the server providing you the output. If you just call up the file from your file system, then it will not be parsed by PHP. If the problems persist anyway, do not hesitate to use one of the many » PHP support options.
The point of the example is to show the special PHP tag format. In this example we used . You may jump in and out of PHP mode in an HTML file like this anywhere you want. For more details, read the manual section on the basic PHP syntax.
Note: A Note on Line Feeds
Line feeds have little meaning in HTML, however it is still a good idea to make your HTML look nice and clean by putting line feeds in. A linefeed that follows immediately after a closing ?> will be removed by PHP. This can be extremely useful when you are putting in many blocks of PHP or include files containing PHP that aren’t supposed to output anything. At the same time it can be a bit confusing. You can put a space after the closing ?> to force a space and a line feed to be output, or you can put an explicit line feed in the last echo/print from within your PHP block.
Note: A Note on Text Editors
There are many text editors and Integrated Development Environments (IDEs) that you can use to create, edit and manage PHP files. A partial list of these tools is maintained at » PHP Editors List. If you wish to recommend an editor, please visit the above page and ask the page maintainer to add the editor to the list. Having an editor with syntax highlighting can be helpful.
Note: A Note on Word Processors
Word processors such as StarOffice Writer, Microsoft Word and Abiword are not optimal for editing PHP files. If you wish to use one for this test script, you must ensure that you save the file as plain text or PHP will not be able to read and execute the script.
Now that you have successfully created a working PHP script, it is time to create the most famous PHP script! Make a call to the phpinfo() function and you will see a lot of useful information about your system and setup such as available predefined variables, loaded PHP modules, and configuration settings. Take some time and review this important information.

PHP — это серверный язык написания скриптов, предназначенный для создания интерактивных веб-страниц. Он стал очень популярен благодаря простоте использования, функциям интерактивности внутри веб-страниц и интеграции с HTML. Только представьте себе, что происходит в момент редактирования страницы даже на этом сайте. За этим процессом стоит множество, а возможно, даже сотни PHP скриптов, контролирующих изменение веб-страниц в зависимости от различных обстоятельств. В данной статье вы узнаете о том, как можно написать несколько очень простых PHP скриптов — так вы получите общее представление об основах работы PHP.
Первые шаги с оператором Echo
- Для запуска «Блокнота» на любой версии Windows можно использовать сочетание клавиш ⊞ Win + R > Notepad.
- Запустить TextEdit на Mac OS можно через меню «Программы» > TextEdit.
- В «Блокноте», добавьте расширение .php к названию файла и заключите в кавычки. Таким образом, «Блокнот» уже не будет считать файл текстовым и не станет преобразовывать его в текстовый формат. Если не добавить кавычки, то имя файла автоматически станет следующим: hello world.php.txt. В качестве альтернативного варианта отключения автоматического добавления расширения .txt при сохранении в меню «Тип файла» можно выбрать значение “Все файлы (*.*)». В этом случае имя файла останется таким, каким вы его введете, и вам уже не нужно будет добавлять кавычки.
- В программе TextEdit не нужно добавлять кавычки в название файла при его сохранении. Вместо этого появится всплывающее окно с запросом на подтверждение того, что вы хотите сохранить файл с расширением .php.
- Убедитесь в том, что сохраняете файл в корневом каталоге документов вашего сервера. Обычно внутри папки сервера Apache на Windows этот каталог называется “htdocs”. Для Mac каталог по умолчанию расположен в /Library/Webserver/Documents, однако путь может быть скорректирован при настройке сервера.
- Если возникнет сообщение об ошибке, проверьте, что код в файле введен в точности как в примере. Убедитесь в том, что не забыли добавить точку с запятой в конце команды.
- Также необходимо проверить, что файл сохранен в правильном каталоге.
