How to use defined in class file with namespace

Question

Here is my code.

defined( 'ABSPATH' ) || exit;

namespace JSR;

class myClass{
...
}

This is giving below error

Global code should be enclosed in global namespace declaration

Any idea how to fix it?

Answer 1

From the PHP manual on defining namespaces:

Namespaces are declared using the namespace keyword. A file containing a namespace must declare the namespace at the top of the file before any other code - with one exception: the declare keyword.

To fix the issue, simply make sure that your namespace declaration comes before the other code:

namespace JSR;

defined( 'ABSPATH' ) || exit;

class myClass{

}

Answer 2

You can use "Use" keyword, to access your class of that namespace.
