Twig is able to speed things up by caching your templates. Pure PHP code is generated and stored in the cache directory.

So, how do we display our first template? First, prepare your template file. It will be very simple, because it contains only the basic output:. Save this file in the templates directory. The convention is to save a template with the. Its content will be as follows:.

In this code, the Twig autoloader is included and registered. In the next step, the environment is initialized with the previously created loader. As a result, the following code is sent to the browser:.

Nothing could be simpler. Just prepare the XML template, like so:. Save it as, say, hello. To generate the result, just load this file instead of index.

This example shows how easy it is to use Twig. Filters are a useful concept and are common to many templating engines. Filters are applied to the variable to change its contents and print it to the template. Take the following code:. This will affect the variable being printed, and all lowercase letters will be switched to uppercase. Filters can be chained, too. So, you could strip out any HTML tags and convert the variable to uppercase with following code:. In templates, most of the operations you will be doing will be looping over a set of data listing some items , sometimes accompanied by conditional statements if … then.

This is why Twig has implemented only for and if control structures, but they are quite powerful. The for loop was presented in its simplest form in the previous section. Below are some more sophisticated examples.

Notice the else block. It is rendered when the array is empty and no iteration takes place. You may have noticed that the author of Twig was highly inspired by the behavior of the for structure in the Python language.

Important: you cannot use break or continue statements in the Twig version of the for loop. On the other hand, you do have access to a few useful variables inside the loop:. The if statement is almost the same as it is in pure PHP.

You can use if , else and elseif tags. For example:. As with the for loop, the operators in Twig are highly inspired by the ones in Python. This covers most of the basic syntax of Twig. To go deeper, you should read the extensive documentation. As the creator of Twig states, template inheritance is the most powerful and important feature of Twig.

Typically this content would all be contained within tags to explain what type of content it is. In the example above we have left this out just to keep things simple. In the next section we'll start to show you what type of tags may be used. If you copy the file above template. Experimenting with it, you will see that you can actually break the rules in quite a few different ways and the browser will happily play along.

Browser vendors realise there is quite a bit of poorly written HTML out there. In an effort to provide the best experience to their users they will do their best effort to work around any errors they come across. As we work through this tutorial, each section will add new tags allowing you to do more interesting things. My suggestion would be that you pick a topic or subject of interest to you and create a page about that. As you work through each section add to and improve the page with the new tags you have learnt.
