PHP color formatting in Kirby forum

I’ve seen color formatting of PHP code blocks. How is that done? Mine are always grey, like this.

echo 'Boring grey code';

Look at Syntax Highlighting in the forum

Add “php” after the three beginning tickmarks

Nice! For anyone else, here it is…

Copy, paste BUT remove the space before the last three tickmarks.

```php
echo 'Colorful PHP code';
