如何将别名类注册为全局类 /Core/Api.php
如何将别名类注册为全局类 /Core/Api.php,php,Php,use仅在当前名称空间内工作（大多数情况下用于整个文件） 您可以创建空类来继承目标类 <?php class Api extends \Core\Api {} <?php include 'vendor/autoload.php' <?php include 'start.php'; use Core\Api as Api; new Api // it's work <?php include 'vendor/autoload.php' us
use<?php
class Api extends \Core\Api
{}
<?php
include 'vendor/autoload.php'
<?php
include 'start.php';
use Core\Api as Api;
new Api // it's work
<?php
include 'vendor/autoload.php'
use Core\Api as Api;
<?php
include 'start.php';
new Api; // Fatal error: Class 'Api' not found
<?php
class Api extends \Core\Api
{}
