PHP array of functions: interpreter unexpectedly calls all functions during evaluation of the array

I have this little helper method here:

private function continueConv($attribute, $next): void
{
    $sequence = [   $this->askName(),
                    $this->askEmail(),
                    $this->askPhone(),
                    $this->manageMessage()
                ];

    match($attribute) {
        'user_name' => $sequence[0 + (int)$next], 
        'user_email' => $sequence[1 + (int)$next], 
        'user_phone' => $sequence[2 + (int)$next]
    };

    return;
}

When the interpreter evaluates the $sequence array, instead of just storing the pointers to those functions, it calls them all!
Is this a bug?
Are there working alternatives?
Thanks

EDIT:
alternative approach that works:

private function continueConv($attribute, $next): void
{

    match($attribute) {
        'user_name' => $next ? $this->askEmail() : $this->askName(), 
        'user_email' => $next ? $this->askPhone() : $this->askEmail(), 
        'user_phone' => $next ? $this->manageMessage() : $this->askPhone()
    };

    return;
}

but I’d prefer to use an array of functions in order to easily change the sequence.

>Solution :

You can use an array containing the object and method name as a callable. So just put the method names in the array.

private function continueConv($attribute, $next): void
{
    $sequence = ['askName', 'askEmail', 'askPhone', 'manageMessage'];

    $func = [$this, match($attribute) {
        'user_name' => $sequence[0 + $next], 
        'user_email' => $sequence[1 + $next], 
        'user_phone' => $sequence[2 + $next]
    }];

    $func();
}
