如果條件在幾小時、幾天內不起作用 (if condition not working for Hours,Days)

問題描述

如果條件在幾小時、幾天內不起作用 (if condition not working for Hours,Days)

見下面的代碼，如果條件不工作，從這段代碼中，我不知道如何寫這個的 if 條件

<?php                          
    $start = $row['t_started_on'];
    $due = date('Y‑m‑d H:i:s');
    $start_date = new DateTime($start);
    $end_date = new DateTime($due);
    $interval = $start_date‑>diff($end_date);
    echo "Result " . $interval‑>y . " years, " . $interval‑>m." months, ".$interval‑>d." days ";
 // upto here i got correct answer.
     if($interval‑>h <="24"){
  $result = $interval‑>h." Hours";// i want like this 10 Hours ago
 }else if ($interval‑>d <="30")){
   $result = $interval‑>d." Days";// i want like this 25 Days ago
 }else{
 $result = $interval‑>m." Months";// i want like this 10 Months ago
 }
    ?>

參考解法

方法 1:

Please try this

<?php                          
    $start = $row['t_started_on'];
    $due = date('Y‑m‑d H:i:s');
    $start_date = new DateTime($start);
    $end_date = new DateTime($due);
    $interval = $start_date‑>diff($end_date);
    echo "Result " . $interval‑>y . " years, " . $interval‑>m." months, ".$interval‑>d." days ";
 // upto here i got correct answer.
     if($interval‑>h <= 24){ // Removed quotes
        $result = $interval‑>h." Hours";// i want like this 10 Hours ago
     }
     else if ($interval‑>d <= 30)){ // Removed quotes
       $result = $interval‑>d." Days";// i want like this 25 Days ago
     }
     else{
       $result = $interval‑>m." Months";// i want like this 10 Months ago
     }
    ?>

方法 2:

    Hi,

One things that we have to check ,is t_started_on coming in Y‑m‑d H:i:s format ?.

Please try this.it should work.

    <?php

        $start = $row['t_started_on'];

        $due = date('Y‑m‑d H:i:s');

        $start_date = new DateTime($start);

        $end_date = new DateTime($due);

        $interval = $start_date‑>diff($end_date);

        echo "Result " . $interval‑>y . " years, " . $interval‑>m." months, ".$interval‑>d." days ";

     // upto here i got correct answer.

         if($interval‑>h <= 24){

      $result = $interval‑>h." Hours";// i want like this 10 Hours ago

     }else if ($interval‑>d <= 30){

       $result = $interval‑>d." Days";// i want like this 25 Days ago

     }else{

       $result = $interval‑>m." Months";// i want like this 10 Months ago

     }

     ?>
Here's example.

$start = '2016‑03‑02 12:00:00 PM';

    $due = date('Y‑m‑d H:i:s');

    echo $due;

    $start_date = new DateTime($start);

    $end_date = new DateTime($due);

    $interval = $start_date‑>diff($end_date);

    echo "Result " . $interval‑>y . " years, " . $interval‑>m." months, ".$interval‑>d." days ";

 // upto here i got correct answer.

     if($interval‑>h <= 24 ){

      $result = $interval‑>h." Hours";// i want like this 10 Hours ago

     }else if ($interval‑>d <= 30 ){

       $result = $interval‑>d." Days";// i want like this 25 Days ago

     }else{

     $result = $interval‑>m." Months";// i want like this 10 Months ago

     }
i got this result : Result 0 years, 0 months, 30 days 21 Hours,it looks liek correct result.
Note : Result may be vary due to timezone.
