PHP 5.3.2：实例化对象的不推荐使用的方法？

问题描述：

Getting a white screen of death, so decided to remote debug an application that I suspect is instantiating an object using a now unsupported method:

$type['content_object'] = new $type['handler_class']();

Is this still legitimate?

获取死亡白屏，因此决定远程调试我怀疑使用now实例化对象的应用程序不支持的方法： p>

$ type ['content_object'] = new $ type ['handler_class']（）; code> p>

这仍然合法吗？ p> div>

答

Assuming $type['handler_class'] is a string containing the name of a class, then it's fine, according to the manual:

If a string containing the name of a class is used with new, a new instance of that class will be created.
<?php
    $instance = new SimpleClass();

    // This can also be done with a variable:
    $className = 'Foo';
    $instance = new $className(); // Foo()
?>
