Smarty comes with several built-in functions. These built-in functions
are the integral part of the smarty template engine. They are compiled
into corresponding inline PHP code for maximum performance.

You cannot create your own [custom
functions](./language-custom-functions.md) with the same name; and you
should not need to modify the built-in functions.

A few of these functions have an `assign` attribute which collects the
result the function to a named template variable instead of being
output; much like the [`{assign}`](./language-builtin-functions/language-function-assign.md) function.
