Answer 1

Use the syntax: $object->{$property} where $property is a string variable and $object can be this if it is inside the class or any instance object

Live example: http://sandbox.onlinephpfunctions.com/code/108f0ca2bef5cf4af8225d6a6ff11dfd0741757f

 class Test{
    public function createProperty($propertyName, $propertyValue){
        $this->{$propertyName} = $propertyValue;
    }
}

$test = new Test();
$test->createProperty('property1', '50');
echo $test->property1;

Result: 50
