Are namespaces case-sensitive in PHP?

Yes, namespaces in PHP are case-sensitive. This means that when referencing namespaces in your code, you must match the case exactly as it is defined. To avoid issues with case sensitivity, it is recommended to consistently use the correct casing when defining and referencing namespaces in your PHP code.

// Example of using namespaces with correct casing
namespace MyNamespace;

use MyNamespace\MyClass;

$obj = new MyClass();
