PHP命名空间namespace用法实例分析

<?php
//命名要使用复合名称
namespace me\mine;
class me{
  public function __construct(){
    echo &#39;name&#39;.&#39;<br>&#39;;
  }
  public function name(){
    echo &#39;i use space&#39;.&#39;<br>&#39;;
  }
}
//$me = new me();
function me(){
  echo &#39;is me&#39;.&#39;<br>&#39;;
}

<?php
class me{
  public function __construct(){
    echo &#39;no namespace&#39;.&#39;<br>&#39;;
  }
}

<?php
//建议使用别名
use me\mine as i;
require &#39;./name.php&#39;;
require &#39;./common.php&#39;;
$me = new i\me();
$me->name();
i\me();
$com = new me();
