Simple Usage Example of PHP Namespace

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

There are three files, space1. php, space2. php, use. php, in the same directory.

space1.php:

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

space2.php:

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

use. php:

<?php
// We all know that the same 1 Directory, you can't store similar files with the same name. You can store files with the same name in different directories. 
// The full name space is similar to the above meaning. 
// If there are two PHP File, it's all in the file 1 A Employees Class. In the same 1 Create two files in Employees Object, definitely not, you can use namespaces at this time. 
$DIR = dirname(__FILE__);
include($DIR.'/space1.php');
include($DIR.'/space2.php');
$obj = new MyNamespace\Factory\Employees('a');
$myName = $obj->getName();
echo "<p>$myName</p>";
$obj = new MyNamespace\Company\Employees('a');
$myName = $obj->getName();
echo "<p>$myName</p>";

Run results:

Factory : a

Company : a
