im pretty sure constructors return an object instance:
php > class Test { function __construct() {} }
php > var_dump(new Test());
object(Test)#1 (0) {
}
but anyway, how could you even test that __construct() returned void
and the new keyword returned a copy of the object? new essentially
invokes __construct() and passes along its return value, near as i can tell.
Christoph,
if you dont want to write a function in the global namespace, as suggested
in the article, Eric posted, just add a simple factory method in your class,
eg.
<?php
class Test {
public static function getInstance() {
return new Test();
}
public function doSomething() {
echo __METHOD__ . PHP_EOL;
}
}
Test::getInstance()->doSomething();
?>
