php命名空间+spl_autoload_register实现类的自动加载

function my_autoload($name){$name = str_replace(‘\\‘,DIRECTORY_SEPARATOR,$name);require $name.‘.class.php‘;}

spl_autoload_register(__NAMESPACE__.‘\\my_autoload‘);

<?phpnamespace Index;use auto\say;use auto\mycolor\color;function my_autoload($name){$name = str_replace(‘\\‘,DIRECTORY_SEPARATOR,$name);require $name.‘.class.php‘;}spl_autoload_register(__NAMESPACE__.‘\\my_autoload‘);$say = new say();$say->hello();$color = new color();$color->test();

b. auto/say.class.php：

<?phpnamespace auto;class say{public function hello(){ ???echo "hello";}}

c. auto/mycolor/color.class.php：

<?phpnamespace auto\mycolor;class color{public function test(){ ???echo "blue";}}
