I have a classname saved in a string in PHP. Is it possible to resolve the class name using a string?
If assuming that I have a class called 'Myclass', I need something like:
'Myclass'::class

@naneri do you want to use it like this `$dynamic_name_of_the_class::class`? – Tintu C Raju Dec 02 '15 at 11:12

@HoschNok no, I need to get a full class name out of a string without creating an object that is a class instance. – naneri Dec 02 '15 at 11:25

2Please elaborate. In what way will/may the "full classname" differ from 'Myclass' ? – VolkerK Dec 02 '15 at 11:51

I'm not entirely clear what use you'd have for ::class against a string. The simple fact is that, if this worked, it would just output the same string as you already have. ie in your example, 'MyClass'::class would output the string MyClass.
Maybe you're trying to have a string that just contains the classname and you're trying to resolve the namespace? This won't work. But you can get the current namespace using the __NAMESPACE__ reserved word:
namespace foo\bar;
echo __NAMESPACE__; //will output 'foo\bar'
You can use this in conjunction with a classname string to build a fully-qualified classname for the current namespace.
If you want to get a classname from a different namespace, then you will have to know the namespace beforehand; without the namespace, PHP won't be able to locate the class at all.
