PHP对日期列排序多维数组

Question

我通过以下方式设置了数组$ dataStoreForTableImport。

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

它包含以下数据

如果articleDate在给定日期之前，我希望能够从此数组中删除行。

我已经尝试了一切，但似乎没有用。 我什至无法按日期正确排序？

日期格式为-2007年2月10日

我用过

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

将其格式化为上面数组中显示的格式。

谁能帮忙吗？

谢谢

对数据库后端中的行进行过滤和排序。 这将改善您的应用程序的性能。 在SQL查询中，使用WHERE子句按日期过滤，并使用ORDER BY子句按日期排序。
