Imagine our `helloworld.html` file looks like this: ```markup

Here's a gift for you: 🧁

``` But we want the gift emoji to be passed as a variable to the pattern to be able to pass a different one each time we make the call to [Patterns::out ](/reference/core-modules/patterns/methods.md#out)or [Patterns::parse](/reference/core-modules/patterns/methods.md#parse). To do so, first we replace the emoji in the `helloworld.html` file with a PHP statement that simply echoes the variable `$emoji`, like this: ```markup

Here's a gift for you:

``` > Note that, to use PHP code inside a pattern, we need to enclose it in PHP's opening and closing tags: ``. In this case, however, we use the shorthand `` which is a shortcut for the more verbose `` And now, in our call to[ Patterns::out](/reference/core-modules/patterns/methods.md#out), we pass `emoji` as a variable: ```php $e->Patterns->out("helloworld.html", [ "variables" => [ "emoji" => "🧸" ] ]); ``` So now, the browser shows this: ```markup Here's a gift for you: 🧸 ``` {% hint style="success" %} See this example working in the [Cherrycake documentation examples](https://documentation-examples.cherrycake.io/example/patternsGuidePassingVariables) site. {% endhint %}
