PHP: Namespace usage: aliases/imports

Namespaces are a mechanism in PHP for organizing and managing code. It allows developers to use the same class, function, and constant names across projects without worrying about conflicts. PHP provides a concise syntax to define namespaces, and also provides alias and import functions to better take advantage of namespaces.

namespace alias

Namespace aliases allow us to create a short and concise alias for a namespace or class for easier use in code. This is especially useful when dealing with long namespace or class names.

Here is an example showing how to use namespace aliases:

namespace My\Long\Namespace\Name;

class MyClass
{
   
    
    
    public function doSomething()
