I haven't seen anyone use an anonymous function but it works! This way you only have to add ONE
function in your parent class instead of cluttering up your children. It works for regular classes,
extended classes, abstract classes, and even classes that inherit interfaces
<?php
class A
{
public static string $name = 'A';
public static string $birthday = 'February';
public static string $hairColor = 'Light Brown';
public static function getProperty(string $propertyName)
{
$property = function ($name): string {
return static::$$name;
};
return $property($propertyName);
}
public static function getProperties()
{
$properties = function () {
return get_class_vars(static::class);
};
return $properties();
}
}
class B extends A
{
public static string $name = 'B';
public static string $birthday = 'February';
public static string $hairColor = 'Blonde';
}
// class A
echo 'My name is: '.A::getProperty('name')."\n";
print_r(A::getProperties());
echo "\n";
// Class B
echo 'My name is: '.B::getProperty('name')."\n";
print_r(B::getProperties());
?>
The result will be:
// My name is: A
// Array
// (
// [name] => A
// [birthday] => February
// [hairColor] => Light Brown
// )
//
// My name is: B
// Array
// (
// [name] => B
// [birthday] => February
// [hairColor] => Blonde
// )
Hopefully this helps someone else that likes simple clean code.
