将参数从php中的数组传递给构造函数

问题描述：

通常，如果我想将参数从 $myarray 传递给 $somefunction，我可以在 php 中使用

Normally, if I want to pass arguments from $myarray to $somefunction I can do this in php using

call_user_func_array($somefunction, $myarray);

然而，当人们希望调用的函数是对象的构造函数时，这不起作用.由于相当明显的原因，它不起作用:

However this does not work when the function one wishes to call is the constructor for an object. For fairly obvious reasons it does not work to do:

$myobj = new call_user_func_array($classname, $myarray);

是否有一些相当优雅的东西确实有效?

is there something fairly elegant that does work ?

答

您可以使用反射 API:

You can use the Reflection API:

示例:

$reflector = new ReflectionClass('Foo');
$foo = $reflector->newInstanceArgs(array('foo', 'bar'));
