How to pass an array as parameters or arguments?

Question

I have two functions:

function example($param1, $param2)
{
    echo $param1 . $param2;
}

function frutas($fruta1, $fruta2, $fruta3)
{
    echo $fruta1 . $fruta2 . $fruta3;
}

And I also have a variable that receives function parameters in the form of a array:

$array = ['param1', 'param2'] // para função example()
or
$array = ['fruta1', 'fruta2', 'fruta3'] // para função fruta()

I can manually pass the values this way:

example($array[0], $array[1])

I don’t want to manually pass because the function frutas for example, it has 3 parameters and not 2. And I would like it to be automatic, passing all arguments. As if it were a foreach.

There’s a way I can do this?

Answer 1

You don’t have much control over it, a lot can go wrong. You have to know what you’re doing.

PHP 5.6

example(...$array);

Documentation. This is usually called splat.

PHP previous to 5.6

call_user_func_array("example", $array);

Documentation.

I recommend avoiding this as much as possible. If you are going to create the function, then make it accept the array also, or do another that accepts a array. It’s much better. Just do it when there’s no other way. Still, for a few arguments (and it’s rare not to be so) I would always do it by hand.
