完蛋了,为什么我感觉 PHP 的语法这么优雅呢

temporal 官网示例

python:

@workflow.defn
class SleepForDaysWorkflow:
    # Send an email every 30 days, for the year
    @workflow.run
    async def run(self) -> None:
        for i in range(12):
            # Activities have built-in support for timeouts and retries!
            await workflow.execute_activity(
                send_email,
                start_to_close_timeout=timedelta(seconds=10),
            )

            # Sleep for 30 days (yes, really)!
            await workflow.sleep(timedelta(days=30))

ruby:


# Send an email every 30 days, for the year
class SleepForDaysWorkflow < Temporalio::Workflow::Definition
  def execute
    12.times do
      # Activities have built-in support for timeouts and retries!
      Temporalio::Workflow.execute_activity(
        SendEmailActivity,
        start_to_close_timeout: 10
      )

      # Sleep for 30 days (yes, really)!
      Temporalio::Workflow.sleep(30 * 24 * 60 * 60)
    end
  end
end

C#:

[Workflow]
public class SleepForDaysWorkflow
{
    // Send an email every 30 days, for the year
    [WorkflowRun]
    public async Task RunAsync()
    {
        for (int i = 0; i < 12; i++)
        {
            // Activities have built-in support for timeouts and retries!
            await Workflow.ExecuteActivityAsync(
                (Activities act) => act.SendEmail(),
                new() { StartToCloseTimeout = TimeSpan.FromSeconds(10) });

            // Sleep for 30 days (yes, really)!
            await Workflow.DelayAsync(TimeSpan.FromDays(30));
        }
    }
}

PHP:

class SleepForDaysWorkflow implements SleepForDaysWorkflowInterface
{
  // Send an email every 30 days.
  public function sleepForDays(): void
  {
      for ($i = 0; $i < 12; $i++) {
          // Activities have timeouts, and will be retried by default!
          $this->sendEmailActivity->sendEmail();

          // Sleep for 30 days (yes, really)!
          Workflow::sleep(30 * 24 * 60 * 60)
      }
  }
}

感觉对于 java 程序员 php 的心智负担好小啊

PHP 最大的问题不是$，而是设计一塌糊涂，例如我要处理一个字符串，我要把这个字符串放在第几个参数？每个处理函数还不一样。

这导致要单独记忆，很多人都是懂多种语言，没谁想单独为某个语言记一些垃圾玩意。

另外就是 JS 这种可以链式调用，自动补全啥的都很优秀，php 这种……语法也不优美，函数套函数，函数套函数，眼睛都看不清楚引号和括号是哪个函数的（当年我写 vb 也有这个问题，烦）

这也是为什么很多人说别学 C#，学了之后学不会其他语言了，因为设计是真的好，由奢入俭难。
