如何在php中比较时间戳的月份与Spinner中选择的月份,php,mysql,Php,Mysql,这是我的report.php <?php require("config.inc.php"); if (!empty($_POST)) { $query = "SELECT * FROM user WHERE position = 'user'"; try { $stmt = $db->prepare($query); $result = $stmt->execute()

这是我的report.php

<?php

    require("config.inc.php");

    if (!empty($_POST)) {

        $query = "SELECT * FROM user WHERE position = 'user'";

        try {
            $stmt   = $db->prepare($query);
            $result = $stmt->execute();
        }
        catch (PDOException $ex) {

            //die("Failed to run query: " . $ex->getMessage());
            $response["success"] = 0;
            $response["message"] = "Database Error 1. Please Try Again!";
            //die(json_encode($response));
        }

        $row = $stmt->fetchAll();

        //No. of shipment that is requested
        $query = "SELECT p.*,s.* FROM parcel p ,shipmentrequest s 
                    WHERE p.parcelstatus= 'requested'
                    AND p.receiverid = s.receiverid
                    AND MONTH(FROM_UNIXTIME(s.requestTime`)) = 05";

        //Again, we need to update our tokens with the actual data:

        try {
            $stmt   = $db->prepare($query);
            $result = $stmt->execute();
        }
        catch (PDOException $ex) {

            //die("Failed to run query: " . $ex->getMessage());
            $response["success"] = 0;
            $response["message"] = "Database Error 2. Please Try Again!";
            //die(json_encode($response));
        }

        $shipmentrow = $stmt->fetchAll();

        $response["success"] = 1;
        $response["message"] = "Summary Report is displayed";
        //echo json_encode($response);

我想问为什么我的查询

$query=“从包裹p，发货请求s中选择p，s.*”
其中p.parcelstatus='请求'
p.receiverid=s.receiverid
和月份（从_UNIXTIME（s.requestTime））=05”
它没有任何MySQL错误，但它不会返回我想要的结果。
我想要的是，当我从Spinner中选择月份时，它将执行查询并获取该月份的数据行数。
根据您的查询，它将始终返回五月的项目（month（）=05
）。如果希望它返回不同的月份，则必须使用$\u POST['month']
作为查询的输入
$query = "SELECT p.*,s.* FROM parcel p ,shipmentrequest s WHERE p.parcelstatus= 'requested' AND p.receiverid = s.receiverid AND MONTH(FROM_UNIXTIME(s.requestTime)) = :month";

$stmt   = $db->prepare($query);
$stmt->bindValue(':month', $_POST['month']);
$result = $stmt->execute();

但问题是，我直接在数据库中的MySQL中尝试查询，也无法根据我选择的月份检索任何内容。您在var_dump（$_POST）时看到预期的输出了吗？我没有看到预期的输出
