PHP對日期列排序多維數組

Question

我通過以下方式設置了數組$ dataStoreForTableImport。

$dataStoreForTableImport['title']
$dataStoreForTableImport['content']
$dataStoreForTableImport['date']
$dataStoreForTableImport['link']
$dataStoreForTableImport['username']
$dataStoreForTableImport['website']

它包含以下數據

如果articleDate在給定日期之前，我希望能夠從此數組中刪除行。

我已經嘗試了一切，但似乎沒有用。 我什至無法按日期正確排序？

日期格式為-2007年2月10日

我用過

$sortDate = date('d/m/Y', strtotime($sortDate));

將其格式化為上面數組中顯示的格式。

誰能幫忙嗎？

謝謝

對數據庫后端中的行進行過濾和排序。 這將改善您的應用程序的性能。 在SQL查詢中，使用WHERE子句按日期過濾，並使用ORDER BY子句按日期排序。
