How to Use CSS in PHP Echo to Add Style (3 Easy Ways)

In this tutorial, learn how to use CSS in PHP echo to add style to the text content. The short answer is: use the style attribute and add CSS to it within single quotes (‘ ‘).

Let’s find out with the examples given below to include CSS in PHP echo.

How to Use CSS in PHP Echo with Style Attribute

You can use the

tag inside the PHP echo statement to add text content. In this tag, you have to add a style attribute within which you can mention CSS as given below:

echo «

This is a text in PHP echo.

» ;

This is a text in PHP echo.

The above example shows the output that changes the appearance of the text content after adding the CSS. You can add as much CSS to it as you want to include.

Add CSS in a Class and Include the Class in PHP Echo

You can mention as many CSS as you want in a class. After that, add the CSS class to the text content with

tag in PHP echo statement as given below:

echo «

This is a text in PHP echo.

» ;

This is a text in PHP echo.

You have to first add as many CSS as you want in a CSS class. The above example added 4 CSS properties in a class to style the text content.

Use Double Quotes and Escape Using Backslash

In addition to the above all methods, you can add CSS class in PHP echo statement using the double quotes. After that, you have to escape the quotes using the slash ( \ ) symbol as given in the example below:

This is a text in PHP echo.

The above example uses the double quotes (” “) escaped using the backslash (\) symbol.

How to Use CSS With PHP

Learn about the different ways to add Cascading Style Sheets (CSS) to your website using PHP—with code samples.

On websites powered by PHP, the HTML markup, CSS style sheets, and JavaScript scripts are stored in PHP files.

Any code that’s not enclosed in a PHP tag (that is, ) doesn’t have to follow PHP syntax and will be outputted as static code to the HTML document that the server generates in response to the browser’s request.

Code that’s enclosed in a PHP tag, on the other hand, has to follow the PHP language syntax and will be outputted dynamically to the HTML file loaded by the user’s browser.

In other words, there’s a static and a dynamic way to add CSS with PHP—and we will go through both of them in the rest of this article.

Adding CSS With PHP the Static Way

In your PHP file, you can inline your CSS code in the style=»» attribute of HTML elements, embed it in a tag in the header, or link to it in a tag, and it will be outputted as it is.

doctype html> html>  head>  style> font-size: 42px;  style>  link rel="stylesheet" href="style.css">  head>  body>  h1 style="color:blue">Hello, world!h1>  body> html>

Will result in the following HTML markup:

doctype html> html>  head>  style> font-size: 42px;  style>  link rel="stylesheet" href="style.css">  head>  body>  h1 style="color:blue">Hello, world!h1>  body> html>

However, this assumes that you’re only writing HTML/CSS code and storing it in a PHP file, in which case you aren’t taking advantage of the PHP scripting language’s ability to make your website dynamic.

Adding CSS With PHP the Dynamic Way

Now that we’ve covered the static way of doing things, let’s take a minute or two to talk about how to add CSS code to your HTML document dynamically.

One of the many things that you can do with PHP is to declare variables and store information in them. You can then reference these variables in your echo PHP statements to output the information stored in them to the screen.

For example, you can store the values for your CSS properties in PHP variables, then output them to the client-side HTML files to dynamically generate your CSS code on every request:

?php  $h1_size = "42px";  $h1_color = "blue";  $stylesheet_url = "style.css"; ?> doctype html> html>  head> ?php  echo "style> font-size: h1_size>>;  style>"  ?> ?php  $url = "style.css";  echo "link rel='stylesheet' href=''>";  ?>  head>  body>  h1  echo "style='color:blue'" ?>>Hello, world!h1>  body> html>

The result is the same as the static example a few paragraphs above. But the difference is that you can define the values of the CSS code—and reuse them across CSS rules.

doctype html> html>  head>  style> font-size: 42px;  style>  link rel="stylesheet" href="style.css">  head>  body>  h1 style="color:blue">Hello, world!h1>  body> html>

But the real power of PHP, as W3Schools explains in this tutorial, comes from its functions.

For example, you can create a function to generate a element with the rel=”” and href=”” attributes stored in variables:

?php  // Define the linkResource() function  function linkResource($rel, $href)   echo "link rel='' href=''>";  > ?>

Using this function, you can link any external CSS style sheet or JS script.

Note the use of single and double quotation marks. If you’re using double quotation marks in your PHP code, you need to use single quotation marks for the HTML code in your echo statements, and vice versa.

If you call the linkResource() function anywhere in your PHP file with the following parameters:

// Call the linkResource() function ?php linkResource("stylesheet", "/css/style.css"); ?>

It will output a DOM element with those parameters to the client-side HTML file:

link rel="stylesheet" href="/css/style.css">

Here’s what this looks like in practice. The server-side PHP file below:

php function linkResource($rel, $href)  echo "";  > ?> doctype html> html> head> php linkResource("stylesheet", "/css/normalize.css"); ?> php linkResource("stylesheet", "/css/style.css"); ?> head> body> h1>Hello, world!h1> body> html>

Will output the client-side HTML file below:

doctype html> html>  head>  link rel='stylesheet' href='/css/normalize.css'>  link rel='stylesheet' href='/css/style.css'>  head>  body>  h1>Hello, world!h1>  body> html>

Note: You can give all of the PHP code a test by executing it in one of my favorite tools, the browser-based PHP sandbox at onlinephp.io.

In Conclusion

There are two ways to add CSS code with PHP. One is the static way, or two hardcode it into your PHP files, and the other is the dynamic way, or to generate with functions and variables.

Now that you know how to use both, you can choose the one that’s right for your project depending on the needs and requirements at hand.

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.
