php - property_exists() to check if static property exists inside class method

one text

Solution:

Updating my code from above to include namespaces. This was the problem that was causing the method to return undefined.

The updated code is as follows:

class Generic
{
    public static $propA = "A";
    private static $propB = "B";
    protected static $propC = "C";

    public static function getProperty(string $property): string
    {
        if (!property_exists('JLDN\Generic', $property)) :
            return "Undefined Property";
        endif;

        return self::$$property;
    }
}

foreach (['propA', 'propB', 'propC', 'nonProperty'] as $prop) :
    printf("<p>Property: %s::%s - %s</p>\n", 'Generic', $prop, print_r(Generic::getProperty($prop), true));
endforeach;

Output:

Property: Generic::propA - A

Property: Generic::propB - B

Property: Generic::propC - C

Property: Generic::nonProp - Undefined Property
