emacle / hello-composer example snippets


// 自定义命名空间，注意不要与已有的重复
// 必须与 composer.json 文件里 autoload 定义的路径一致
// "emacle\\HelloComposer\\": "src/"
namespace emacle\HelloComposer;

// 类名与文件名保持一致，文件名不区分大小写
class HelloComposer
{
	// 静态方法 static 使用时，可不用声明类，直接调用方法
    public static function greet($greet = "Hello Composer!")
    {
        return $greet;
    }
}


use emacle\HelloComposer\HelloComposer;  // 引入 namespace 并加入类名 HelloComposer


    $test = new HelloComposer(); // 声明类 HelloComposer
    var_dump($test->greet()); // 调用 HelloComposer类方法 greet()
   
    var_dump(HelloComposer::greet()); // 如果类方法greet为 static 方法则不用声明直接调用
