[{{ page.title }}]({{ page.url | absolute_url }}) redeclares all core PHP functions. The new PHP functions act exactly as the old ones, except they throw exceptions properly when an error is encountered.

The "safe" functions have the same name as the core PHP functions, except they are in the Safe namespace.

Note: {{ page.title }} can be integrated with both PHPStan and Rector. Check out the documentation for more information.
