wish of those help The problem is how you're referencing the class variable inside your methods. Look:
code :
public function dbConnect() {
    $conn = mysqli_connect($this->host,$this->username,$this->password);
    ...
$this->conn = mysqli_connect(...);

will help you Do it when it's absolutely needed (and avoid it whenever possible).
The only task of a getter is to return the data, perhaps after a transformation to make it more easy to use.
code :
long _ticks = 500000000000L;
public long GetTicks() 
{
    return _ticks;
}
public string GetTicks() 
{
    return _ticks.ToString();
}

may help you . The public method Employee.prototype.publicGetFullName has to be defined outside Employee constructor function.
When you use it inside and refer to a private function, then it will be redefined on each instantiation and so it will return the 'private' data of the last created instance instead of this instance.

To fix the issue you can do I have a config.php: , you can do this by replacing $config with $this
code :
class DataBase extends GConfig {
       function opendb() {
           $node = mysqli_connect($this->DbServer, ($this->DbUser, $this->DbPassword);
           mysqli_select_db($node, $this->DbName);
           mysqli_set_charset($node, "$this->CharSet");
           return $node;
       }

}

I wish this helpful for you With "globalization" of var $b before storing value into it, it works fine for me. Snippet here:
code :
call_user_func(function () {
    global $b;
    $b = 42;
    var_dump("b: " . $b);

    $instance = new class
    {
        function foo()
        {
            global $b;
            var_dump("b: " . $b);
        }
    };

    $instance->foo();
});

To fix this issue You're thinking of the JVM as a bunch of Java code in some other package, which therefore couldn't access the main method hidden in your class with default accessibility. But it's not. The JVM is the virtual machine on which Java code is run; it decides what is and is not accessible to other Java code. In particular, it can run whichever methods it likes, regardless of their accessibility.
