Example of simple usage of PHP namespace

This article describes the simple usage of PHP namespace. Share it for your reference, as follows:

There are three files, namely, bar, in the same directory.

：

<?php
namespace MyNamespace\Factory;
class Employees{
  private $name;
  function __construct($nameStr){
    $this->name = $nameStr;
  }
  function getName(){
    return 'Factory : '.$this->name;
  }
}

：

<?php
namespace MyNamespace\Company;
class Employees{
  private $name;
  function __construct($nameStr){
    $this->name = $nameStr;
  }
  function getName(){
    return 'Company : '.$this->name;
  }
}

：

&lt;?php
//We all know that in the same directory, the same file of the same name cannot be stored.  Then you can store files with the same name in different directories.//The full namespace is similar to the above meaning.//If there are two PHP files, there is an Employees class in the file.  Creating two Employees objects in the same file is definitely not possible, and you can use the namespace at this time.$DIR = dirname(__FILE__);
include($DIR.'/');
include($DIR.'/');
$obj = new MyNamespace\Factory\Employees('a');
$myName = $obj-&gt;getName();
echo "&lt;p&gt;$myName&lt;/p&gt;";
$obj = new MyNamespace\Company\Employees('a');
$myName = $obj-&gt;getName();
echo "&lt;p&gt;$myName&lt;/p&gt;";

Running results:

Factory : a

Company : a
