PHP如何四捨五入總計

Question

我很困惑在PHP中使用循環函數，我在我的系統中使用PHP做了一些計算函數，但答案仍然不是四捨五入。

我希望所有的總數都在percent_complete之內。

有人可以幫我修復這段代碼嗎？這是原代碼..

<?php echo $row_sr1['percent_complete'] = ($row_sr1['partial_complete'] + $row_sr1['full_complete'])/$row_sr1['appt_today'] * 100;?> 

，這裏是代碼，我已經嘗試圓，但不成功。

<?php echo round($row_sr1['percent_complete']),2 = ($row_sr1['partial_complete'] + $row_sr1['full_complete'])/$row_sr1['appt_today'] * 100;?> 

Answer 1

你的輪功能是在錯誤的地方。

<?php 
    echo $row_sr1['percent_complete'] = 
     round(
      ($row_sr1['partial_complete'] + $row_sr1['full_complete'])/
      $row_sr1['appt_today'] * 100, 
      2); 
?>
