create function

[frankz]

you can get some help, to create and use functions in fat free ?

Thanks

[ved]

What exactly do you mean?

F3 is plain php so to create functions you use:

function myFunction() {
    echo 'This is a function';
}

Somehow I guess this is not what you're asking? 

[frankz]

I said that badly.
for variables use F3-> set ( 'var', 'fair') and are global, and for functions?

[ikkez]

it's the same:

$f3->set('var', function(){ return "value"; });

$val = $f3->var();

[ved]

Try:

$f3->set('myfunc', function($a,$b) {
    return $a+$b;
});

And on your templates:

{{ @myfunc(2,3) }}

[Summer White]

This can't be used in the template language though can it?

$f3->set('var', function() { return 1+1; });

{{ var() }}

[bcosca]

Yes you can:

{{ @var() }}

If you like to encapsule everything in a class this should work as well:

{{ \helper\toolbox::instance()->dosomething(@foo) }}

namespace helper;
class toolbox extends \prefab
{

...

    /**
     * Send bar to client
     */
    public function dosomething($foo) {
        return $bar

    }

and if the function does not return void ?

hmmm unsure if I understand your question correctly.

• For php 7.1 void as return type was accepted 
  
• before 7.1 you return just NULL
  
• if you have something to return than return it ;) return ($my_new_converted_array)
