How to convert timestamp in thinkphp?

ThinkPHP (current date, specified date) time and timestamp conversion

1. Year, month, day, hour, minute and second, time and timestamp conversion

public function test()
  {
    //获取当前日期
      echo '直接获取到的当前日期'.date('Y-m-d H:i:s');
      echo "\n";//换行
    //当前时间时间戳转日期的转换
      $time = time(); //获取当前时间戳
      echo '当前的时间戳'.$time;
      echo "\n";//换行
      $date = date('Y-m-d H:i:s', $time);//时间戳转换为日期格式
      echo '当前时间戳转换后日期'.$date;
      echo "\n";//换行
    //指定时间的转换  
      $str='1666146455';//指定时间戳
      echo '指定时间戳转换为时间'.date("Y-m-d H:i:s",$str);
      echo "\n";//换行
      $str='2022-10-19 11:50:50';//指定时间
      echo '指定日期转换为时间戳'.strtotime($str);
  }

Output results

2. Conversion of year, month, day, time and timestamp

1. Transform directly through the above

public function test()
  {
    //获取当前日期
      echo '直接获取到的当前日期'.date('Y-m-d');
      echo "\n";//换行
    //当前时间时间戳转日期的转换
      $time = time(); //获取当前时间戳(包含时分秒)
      $date = date('Y-m-d', $time);//时间戳转换为日期格式
      echo '当前时间戳转换后日期'.$date;
      echo "\n";//换行
      echo '当前日期转换为时间戳'.strtotime($date);
      echo "\n";//换行
    //指定时间的转换  
      $str='1666146455';//指定时间戳
      echo '指定时间戳转换为时间'.date("Y-m-d ",$str);
      echo "\n";//换行
      $str='2022-10-19';//指定时间
      echo '指定日期转换为时间戳'.strtotime($str);
  }

Output result

2. Convert through mktime, date_parse_from_format

public function test()
  {
    //当前日期的转换
        $date_new = date('Y-m-d'); //获取当前日期2022-10-19
        //日期转换为时间戳
        $arr = date_parse_from_format('Y-m-d', $date_new);
        $time = mktime(0, 0, 0, $arr['month'], $arr['day'], $arr['year']);
        echo '对应时间戳为：' . $time; 
        echo "\n";//换行
        //时间戳转换为日期
        $time1 = date("Y-m-d ", $time);
        echo '对应时间为：' . $time1; //2022-10-12
        echo "\n";
    //指定日期的转换
        $str = '2022-10-19'; //或者 2018年10月1日，中间的符号可以是任何
        $arr = date_parse_from_format('Y-m-d', $str); //如果是2022年10月19日,那么这里就是 Y年m月d日，上下需要保持一致
        $time = mktime(0, 0, 0, $arr['month'], $arr['day'], $arr['year']); //转换为时间戳
        echo '对应时间戳为：' . $time;
        echo "\n";
        //时间戳转换为日期
        $time1 = date("Y-m-d ", $time);
        echo '对应时间为：' . $time1;
  }

Output result
