Question

您好如何在数组中执行此操作。我希望REMARKS显示单词＆＃34; Stopped＆＃34;当速度低于10Kph

时

这是我的代码

array(
                  'account' => $rowmaxtec['ACCOUNT'],
                  'trxdate' => $rowmaxtec['TRXDATE'],
                  //'trxtime' => date('H:i:s',strtotime("+8 Hours",strtotime($rowmaxtec['gpsdate'] . ' ' . $rowmaxtec['gpstime']))),
                 // 'trxtime' => $gpsdatetimeg,
                 'trxtime' => $philtime,
                  'long' => $rowmaxtec['LONG'],
                  'lat' => $rowmaxtec['LAT'],
                  'location' => callback($rowmaxtec['LOCATION']),
                  'direction' => $rowmaxtec['DIRECTION'],
                  'compass' => $rowmaxtec['COMPASS'],
                  'id' => $rowmaxtec['ID'],
                  'events' => $rowmaxtec['Events'],
                  'remarks' => $rowmaxtec['REMARKS'],    -----------------------REMARKS
                  'status' => $rowmaxtec['devicestatus'],
                  'kmrun' => $kmrun,
                  'speed' => $rowmaxtec['speed'],          <------if this is  less than 10kph then REMARKS must be masked/overwritten by the word Stopped
                  'totalkm' => $total,
        'engine' => $rowmaxtec['ENGINE']
                  );

很抱歉，因为这是我第一次在数组中执行if else语句。

Answer 1

使用三元运算符

'remarks' => ($rowmaxtec['speed'] < 10) ? 'Stopped' : $rowmaxtec['REMARKS'],

如果你要处理$rowmaxtec['speed'] < 10的格式（即如果它不是一个简单的整数），

$rowmaxtec['speed']可以用函数替换

快速举例，如果你考虑10Kph＆＃39; ：

function speed_check ($speed, $check_value = 10) {
   return substr($speed, 0, -3) < $check_value;
}

'remarks' => (speed_check($rowmaxtec['speed'])) ? 'Stopped' : $rowmaxtec['REMARKS'],

Answer 2

您可以尝试使用if shorthands将其全部内联写入：

'remarks' => (($rowmaxtec['speed'] < 10)?"STOP":$rowmaxtec['remarks'])

Answer 3

如果符合以下条件，您可以做简写：

$rowmaxtec['speed'] <= 10 ? "STOPPED" : $rowmaxtec['REMARKS'];

所以：

array(
              'account' => $rowmaxtec['ACCOUNT'],
              'trxdate' => $rowmaxtec['TRXDATE'],
              //'trxtime' => date('H:i:s',strtotime("+8 Hours",strtotime($rowmaxtec['gpsdate'] . ' ' . $rowmaxtec['gpstime']))),
             // 'trxtime' => $gpsdatetimeg,
             'trxtime' => $philtime,
              'long' => $rowmaxtec['LONG'],
              'lat' => $rowmaxtec['LAT'],
              'location' => callback($rowmaxtec['LOCATION']),
              'direction' => $rowmaxtec['DIRECTION'],
              'compass' => $rowmaxtec['COMPASS'],
              'id' => $rowmaxtec['ID'],
              'events' => $rowmaxtec['Events'],
              'remarks' => $rowmaxtec['speed'] <= 10 ? "STOPPED" : $rowmaxtec['REMARKS'],    -----------------------REMARKS
              'status' => $rowmaxtec['devicestatus'],
              'kmrun' => $kmrun,
              'speed' => $rowmaxtec['speed'],
              'totalkm' => $total,
    'engine' => $rowmaxtec['ENGINE']
              );

如果在数组内部
