如何使用foreach（）插入HTML而不使用echo

I have this working code in my view:

<?php
                $task_num = 0;
                foreach ($curent_day->getTasksList() as $task){

                    echo '<div class="task">';
                        echo '<span class="task_id">'.($task_num+1).'.'.'</span>';
                        echo '<div class="task_time">';
                            echo '<span class="task_time_start">'.$task->getStartTime().'</span>';
                            echo '<span class="task_time_finish">'.$task->getFinishTime().'</span>';
                        echo '</div>';
                        echo '<a href="/" class="task_name">'.$task->name.'</a>';
                        echo '<a href="/" class="btn task_start btn_disabled">Start</a>';
                        echo '<a href="/" class="btn task_finish btn_disabled">Finish</a>';
                        echo '<div class="status_round '.$task->status.'"></div>';
                    echo '</div>';

                $task_num++;

                }
?>

Is there any way to get rid of 'echo'? P.S. and is the way to insert HTML with HTML helper more correct even if it takes more space?

You can drop echo completely and use native HTML syntax:

<?php $task_num = 0 ?>
<?php foreach ($curent_day->getTasksList() as $task): ?>
    <div class='task'>
        <span class='task_id'><?= ++$task_num ?></span>
        <div class='task_time'>
            <span class='task_time_start'><?= $task->getStartTime() ?></span>
            <span class='task_time_finish'><?= $task->getFinishTime() ?></span>
        </div>
        <a href='/' class='task_name'><?= $task->name ?></a>
        <a href='/' class='btn task_start btn_disabled'>Start</a>
        <a href='/' class='btn task_finish btn_disabled'>Finish</a>
        <div class='status_round <?= $task->status ?>'></div>
    </div>
<?php endforeach ?>

This will give you better syntax highlighting and autoformatting support in your IDE/editor.

There are several different ways that you can concatenate the string by using single quotes and double quotes, or by using a variable and the ".=" operator to append text onto the end of a string. Just google php strings & concatenation and it will have more than you need to figure this out.

But using you example here is a method:

$task_num = 0;
foreach ($curent_day->getTasksList() as $task){
echo 
'<div class="task">' .
  '<span class="task_id">' . ($task_num+1) . '.'.'</span>' .
    '<div class="task_time">' .
    '<span class="task_time_start">' . $task->getStartTime() . '</span>' .
    '<span class="task_time_finish">' . $task->getFinishTime() . '</span>' .
    '</div>' . 
  '<a href="/" class="task_name">'.$task->name.'</a>' . 
  '<a href="/" class="btn task_start btn_disabled">Start</a>' . 
  '<a href="/" class="btn task_finish btn_disabled">Finish</a>' . 
  '<div class="status_round '.$task->status.'"></div>' .
'</div>';

$task_num++;

}

You have to echo to output you data to the browser.

You need not use string concatenation or multiple echo statements.

Alternative

$task_num = 0;
  foreach ($curent_day->getTasksList() as $task){
    $task_num++;
    echo
      "<div class='task'>
        <span class='task_id'>{$task_num}</span>
          <div class='task_time'>
          <span class='task_time_start'>{$task->getStartTime()}</span>
          <span class='task_time_finish'>{$task->getFinishTime()}</span>
          </div>
        <a href='/' class='task_name'>{$task->name}</a>
        <a href='/' class='btn task_start btn_disabled'>Start</a>
        <a href='/' class='btn task_finish btn_disabled'>Finish</a>
        <div class='status_round {$task->status}'></div>
      </div>";

    }

You can concatenate your html in one variable and then you can use it with one time echo statement

<?php
            $task_num = 0;
            $html = '';
            foreach ($curent_day->getTasksList() as $task){
                $html .= '<div class="task">';
                $html .= '<span class="task_id">'.($task_num+1).'.'.'</span>';
                $html .= '<div class="task_time">';
                $html .= '<span class="task_time_start">'.$task->getStartTime().'</span>';
                $html .= '<span class="task_time_finish">'.$task->getFinishTime().'</span>';
                 $html .= '</div>';
                 $html .= '<a href="/" class="task_name">'.$task->name.'</a>';
                 $html .=  '<a href="/" class="btn task_start btn_disabled">Start</a>';
                 $html .= '<a href="/" class="btn task_finish btn_disabled">Finish</a>';
                 $html .= '<div class="status_round '.$task->status.'"></div>';
                $html .=  '</div>';

            $task_num++;
