hello,
i am trying to learn oop, so i made a class that generates passwords.
there are several arrays and from some or each array there are elements
picked(at random) that
form the password.
the problem is: when i make an object the password shows.
but when i reload the page several times and/or changing the values that
form the
password (bv changing $test -> value = true, in , $test -> value -> false)
than nothing happens.
there is no password on the page and no error message, nothing.
the page is complely blank.
is there something wrong with the class?
thanks,
------------------------ code to show password -----------
// make an object;
$test = new WachtwoordGenerator();
// choose the amount of elements from each array;
$test -> kLetter = 8;
$test -> hLetter = 3;
$test -> cijfer = 2;
$test -> leesteken = 4;
// true means that the password contains only unique elements;
// false means that duplicates are allowed;
$test -> uniek = true;
// make the password;
$test -> maakWachtwoord();
// show the password
echo $test -> output();
------------------------- source code from the
class --------------------------------
class WachtwoordGenerator{
private $a;
private $b;
private $c;
private $d;
// amount of elements to choose;
