php - 在mysql和php中搜索两个日期

Question

您好，我想搜索用户表中存在的项目。我写的代码是

$fromdate = date("Y-m-d H:i:s", strtotime($_POST['fromdate']));
$todate = date("Y-m-d H:i:s", strtotime($_POST['todate']));

$s="SELECT * FROM logs WHERE dt BETWEEN $fromdate AND $todate  ORDER BY dt DESC ";
$x = mysql_query($s);

但是输出没有显示。请有人帮助我。

Answer 1

需要在 '$fromdate' 和 '$todate' 周围加上引号

$s="SELECT * FROM logs WHERE dt BETWEEN '$fromdate' AND '$todate' ORDER BY dt DESC ";
