在mysql和php中的两个日期之间搜索

Question

您好我想搜索表用户中存在的项目。 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);

但是输出未显示。 请有人帮我。

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 ";

Answer 2

$fromdate = strtotime($_POST['fromdate']);
$todate = strtotime($_POST['todate']);

$query="SELECT * FROM logs WHERE UNIX_TIMESTAMP(dt) BETWEEN $fromdate AND $todate  ORDER BY dt DESC ";
