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.

Как вставить HTML, CSS и JS в PHP-код?

Когда вы разрабатываете свой модуль, то иногда прибегаете к помощи верстки (HTML и CSS) и дополнительным скриптам.

Все это можно подключать отдельно – что-то в теле страницы, что-то в отдельных файлах. Но некоторые дополнения лучше вставлять непосредственно в сам PHP-файл.

Сегодня я покажу два варианта, как можно вставить HTML, CSS или JavaScript в код PHP.

Первый вариант вставки элементов в PHP-код

Я думаю, что если вы хоть немного знакомы с PHP, то знаете, что такое «echo» (тег, с помощью которого вы можете вывести сообщение на экран).

Вот с помощью него и можно вывести один из перечисленных ранее кодов. Пример:

   "; echo $content; ?>

На что здесь стоит обратить внимание? Кавычки. Если вы используете внешние кавычки в виде » «, то внутренние кавычки элементов должны быть ‘ ‘ и наоборот, иначе вы получите ошибку. Если вы принципиально хотите использовать одинаковые и внешние, и внутренние кавычки, то во внутренних ставьте знак экранизации:

   "; echo $content; ?>

В этом случае все будет работать корректно.

Второй вариант вставки элементов в PHP-код

Этот вариант мне нравится куда больше, чем первый. Здесь мы будем также использовать «echo», как и в предыдущем варианте, но добавим еще элемент «HTML»:

Сюда вы можете вставлять любой элемент, будь то HTML-код или же JavaScript. Кавычки здесь не играют роли (можете вставить любые), а по желанию можно внедрить переменные для вывода:

 "; echo    HTML; ?>

Весьма удобный способ для реализации ваших идей.

How to Use HTML Inside PHP on the Same Page

Here in this file as you can see that PHP code is being put inside html tags namely HTML tag and BODY tag and php code is written inside PHP delimiters (lines 4 and 7) $name=”your name”; is a variable that stores the string inside ” ” and here string stores in variable name is Your name $ is used to declare a variable in PHP. Right now this is the only thing I know about variables and how to declare them in PHP. I am planning to read more about it later and then I’ll record what I understand through the blog post. print $name; Here I have used Print to show the value stored in the variable $name .

print is not actually a real function (it is a language construct) so you are not required to use parentheses with its argument list.

There is more to this function I suppose and will study it in detail. I could also have used echo to obtain the same thing. In line 10 see that I have put PHP code inside the bold html tag ( ) which resulted in bold faced “your name” string. So this way you can put your PHP scripts inside any HTML tags. There are other alternative PHP delimiters you can use to tell server to distinguish between your php script and other webpage elements.
Although these alternative PHP delimiters can be used but I have read that these forms should be avoided and you in practice should use following PHP delimiter as used firstly inside HTML file

Html code inside PHP tags and using echo or print to show those HTML elements

We can use html tags inside PHP also as given below

" echo "" $name="your name"; print $name; echo "
" echo "" print $name; echo "" echo "" echo "" ?>

So we can basically echo all the HTML construct and get it working.Another example could be

Using PHP and HTML on the Same Page

Angela Bradley is a web designer and programming expert with over 15 years of experience. An expert in iOS software design and development, she specializes in building technical hybrid platforms.

Want to add HTML to a PHP file? While HTML and PHP are two separate programming languages, you might want to use both of them on the same page to take advantage of what they both offer.

With one or both of these methods, you can easily embed HTML code in your PHP pages to format them better and make them more user-friendly. The method you choose depends on your specific situation.

HTML in PHP

Your first option is to build the page like a normal HTML web page with HTML tags, but instead of stopping there, use separate PHP tags to wrap up the PHP code. You can even put the PHP code in the middle if you close and reopen the and ?> tags.

This method is especially useful if you have a lot of HTML code but want to also include PHP.

Here’s an example of putting the HTML outside of the tags (PHP is bold here for emphasis):

My Example

//your PHP code goes here
?>
Here is some more HTML
//more PHP code
?>

As you can see, you can use any HTML you want without doing anything special or extra in your PHP file, as long as it’s outside and separate from the PHP tags.

In other words, if you want to insert PHP code into an HTML file, just write the PHP anywhere you want (so long as they’re inside the PHP tags). Open a PHP tag with and then close it with ?> like you see above.

Use PRINT or ECHO

This other way is basically the opposite; it’s how you’d add HTML to a PHP file with PRINT or ECHO, where either command is used to simply print HTML on the page. With this method, you can include the HTML inside of the PHP tags.

This is a good method to use for adding HTML to PHP if you only have a line or so to do.

In this example, the HTML areas are bold:

Echo "";
Echo
"";
Echo
"My Example";
//your php code here
Print
"Print works too!";
?>

Much like the first example, PHP still works here regardless of using PRINT or ECHO to write HTML because the PHP code is still contained inside the proper PHP tags.
