# Twig

## Snippets

Prevent returned HTML from being auto-escaped by Twig ([source](https://stackoverflow.com/a/44736733/937377)):

```php
class MyParser {
    public function getHTML() {
         $rawString = '<a href="#">Hello World</a>'
         return new \Twig\Markup( $rawString, 'UTF-8' );
    }
}
```

* Search order:
  * check if foo is an array and bar a valid element;
  * if not, and if foo is an object, check that bar is a valid property;
  * if not, and if foo is an object, check that bar is a valid method (even if bar is the constructor - use \_\_construct() instead);
  * if not, and if foo is an object, check that getBar is a valid method;
  * if not, and if foo is an object, check that isBar is a valid method;
  * if not, and if foo is an object, check that hasBar is a valid method;
  * if not, return a null value.
* foo\['bar'] on the other hand only works with PHP arrays:
  * check if foo is an array and bar a valid element;
  * if not, return a null value.
