Author

Aleksandar Zivanovic

This package provides a trait to implement the singleton design pattern.

The trait provides functions that return a new instance of the class if none was created so far, or an already created instance of the class otherwise.

It may also force creating a new instance of the class even if another was created.

The trait uses reflection to call the class constructor passing any arguments as a list or as an array.

require_once __DIR__ . '/class.Example.php';

$cat = Example::getSharedInstance('Cat', 'MEOW');
$brownCat = Example::getSharedInstance('Brown Cat', 'BREOW'); // Brown cat will sound same as $cat as its same instance
$dog = Example::getNewInstance('Dog', 'WOF');

$breakLine = php_sapi_name() === 'cli' ? "\n" : '<br>';

$cat->makeSound($breakLine);
