用PHP组织日期

我喜欢首先使用数组索引对项目进行分组。

控制器

$months = array();
foreach ($rows as $row) {
    $month = date('F Y', strtotime($row['date']);

    if (!isset($months[$month]) {
        $months[$month] = array();
    }

    $months[$month][] = $row;
}

视图

foreach ($months as $month => $events) {
    echo '<h2>' . $month . '</h2>';
    foreach ($events as $event) {
        // ...
    }
}

迭代事件;跟踪上个月看到的事件。如果是当月!=上个月,显示月份分隔符。

$lastDate = '';

foreach ($events as $e)
{   
    $currDate = date('F Y', $e->date);
    if ($currDate != $lastDate )
    {
        echo "<h1>$currDate</h1>";
    }
    // might want to format the date to be human readable here...
    echo "<li>$e->date, $e->event"; 
    $lastDate = $currDate;

}
