php - SQL 查询未将日期读取为字符串

Question

这段代码有效

$date = "12/09/2016";
$sql = "SELECT  * FROM someTable.forum_posts_queue where post_owner='admin' and post_create_time = '".$date."' order by post_id desc limit 0,1";

但是，我想将日期设置为变量并将其作为字符串传递

$date = date("m/d/Y");
$sql = "SELECT  * FROM someTable.forum_posts_queue where post_owner='admin' and post_create_time = '".$date."' order by post_id desc limit 0,1";

这不会像上面一样读取日期，并且不理解查询。

Answer 1

使用

$date = date("Y-m-d");

应该可以解决您的问题(假设“post_create_time”字段的类型是 DATE、DATETIME 或 TIMESTAMP)。
