Comment obtenir une série d'heures à partir d'une heure de début et d'une heure de fin, chacune espacée d'une heure en utilisant PHP ?

Question

$course_hour = 1; $starttime = '07:00'; $endtime = '16:00';

Je veux qu'il renvoie un tableau de valeurs comme celui-ci : si

$course_hour = 1;

$return_array = array('07h00 - 08h00', '08h00 - 09h00', '09h00 - 10h00', '10h00 - 11h00', '11h00 - 12h00', '12h00 - 13h00', '13h00 - 14h00', '14h00 - 15h00', '15h00 - 16h00'); si

$course_hour = 1.5;

$return_array = array('07h00 - 08h30', '8h30 - 10h00', '10h00 - 11h30', '11h30 - 13h00', '13h00 - 14h30', '14h30 - 16h00'); si

$course_hour = 2;

$return_array = array('07h00 - 09h00', '09h00 - 11h00', '11h00 - 13h00', '13h00 - 15h00');< /p>

function get_session_times($course_hour, $start_time, $end_time){
    if(strlen($start_time) < 5) $start_time = '0'.$start_time;
    if(strlen($end_time) < 5) $end_time = '0'.$end_time;
    $current_time = date("Y-m-d H:i");
    $session_starttime = date("Y-m-d H:i", strtotime(date("Y-m-d ").$start_time));
    $session_endtime = date("Y-m-d H:i", strtotime(date("Y-m-d ").$end_time));
    $session_starttime_ms = strtotime($session_starttime);
    $session_endtime_ms = strtotime($session_endtime);
    $session_times_array = array();
    for ($i = $session_starttime_ms; $i < $session_endtime_ms; ) { 
         $session_times_array[] = date("H:i", $i)."<br/>"; 
         $i = $i + ($course_hour * 60 * 60);
    }
    return $session_times_array;
}

<?php 
$course_hour = 1.5; // 1 || 1.5 || 2
$starttime = '07:00';
$endtime = '16:00';
 
print_r(get_time_range($course_hour, $starttime, $endtime));

function get_time_range($course_hour, $starttime, $endtime){
  $to_add = '';
  switch($course_hour):
    case 1:
     $to_add = " +1 hours";
     break;
   case 1.5:
     $to_add = " +1 hours 30 minutes";
     break;
   case 2:
     $to_add = " +2 hours";
     break;
   default:
     $to_add = " +1 hours";
     break;
  endswitch;

 // get the total hours
 $from_time = strtotime($starttime); 
 $to_time = strtotime($endtime); 
 $diff_mins = round(abs($from_time - $to_time)/60);
 $diff_hours = $diff_mins/60;

 $hours_arr =[];

 for($i=1; $i<=$diff_hours; $i+= $course_hour):

   $new_end_strtime = strtotime($starttime . $to_add);
   $endtime = date('H:i', $new_end_strtime);

   if($new_end_strtime <= $to_time): // checking the last end time is not greater than defined $endtime
     $str = $starttime . ' - '. $endtime;
     $tmp = strtotime($starttime . $to_add);
     $starttime = date('H:i', $tmp);
     array_push($hours_arr, $str);
   endif;

  endfor;

  return $hours_arr;
}
?>

Vous devez convertir en heures et minutes selon 1, 1.51.5). com/a/27497314/128761">Cette réponse.

J'ai ensuite utilisé le code de cette réponse mentionné par mickmackusa pour obtenir le tableau horaire.

C'est un test.

/**
 * This function is for test the result only. It is no need in your real project.
 */
function testResult($result, $expect)
{
    if (!is_array($result) || !is_array($expect)) {
        throw new Exception('The result and expect must be array.');
    }
    
    $totalResult = count($result);
    $totalExpect = count($expect);
    $totalTested = ($totalResult === $totalExpect);
    unset($totalResult, $totalExpect);

    foreach ($result as $index => $eachResult) {
        if (isset($expect[$index]) && $expect[$index] === $eachResult) {
            // matched.
        } else {
            throw new Exception('The result and expect at index ' . $index . ' does not matched. (' . $eachResult . ')');
        }
    }
    
    return $totalTested;
}

// run tests
$result = getSessionTimes(1, '07:00', '16:00');
$expect = ['07:00 - 08:00', '08:00 - 09:00', '09:00 - 10:00', '10:00 - 11:00', '11:00 - 12:00', '12:00 - 13:00', '13:00 - 14:00', '14:00 - 15:00', '15:00 - 16:00'];
print_r($result);
var_dump(testResult($result, $expect));

$result = getSessionTimes(1.5, '07:00', '16:00');
$expect = ['07:00 - 08:30', '08:30 - 10:00', '10:00 - 11:30', '11:30 - 13:00', '13:00 - 14:30', '14:30 - 16:00'];
print_r($result);
var_dump(testResult($result, $expect));

$result = getSessionTimes(2, '07:00', '16:00');
$expect = ['07:00 - 09:00', '09:00 - 11:00', '11:00 - 13:00', '13:00 - 15:00'];
print_r($result);
var_dump(testResult($result, $expect));

Le résultat sera...
