How can a PHP developer efficiently manage and display news items with distinct dates to avoid repetition?

To efficiently manage and display news items with distinct dates to avoid repetition, PHP developers can use an array to store the dates of the news items. By checking if a date already exists in the array before displaying a news item, developers can prevent duplicate dates from being displayed. 

$newsItems = [
    ['title' => 'News Item 1', 'date' => '2022-01-01'],
    ['title' => 'News Item 2', 'date' => '2022-01-02'],
    ['title' => 'News Item 3', 'date' => '2022-01-02'],
    ['title' => 'News Item 4', 'date' => '2022-01-03']
];

$displayedDates = [];

foreach ($newsItems as $item) {
    if (!in_array($item['date'], $displayedDates)) {
        echo $item['title'] . ' - ' . $item['date'] . '<br>';
        $displayedDates[] = $item['date'];
    }
}
