如何检查查询之一是否在PHP MySQL中的数据范围内？

Question

我在这里有问题

如何检查输入之一在数据范围内？ 第一个if语句仅在两个数据具有相同的值或两个数据在数据范围之间时才执行

但是如果其中一个数据在范围内，则不会执行

我的问题是，如何检查输入之一是否在范围之间？

代码如下：

<?php
    $connect      = mysqli_connect("", "root", "", "");
    global $connect;   

    if(isset($_POST['Submit'])){
        $time_out   = $_POST['time_out'];
        $time_enter = $_POST['time_enter'];

        $sql = "SELECT * FROM table";
        $get = mysqli_query($connect,$sql);
        if($get && mysqli_num_rows($get) > 0 ){              
            while($row = mysqli_fetch_assoc($get)){

            $time_out_db    = $row['time_out'];
            $time_enter_db  = $row['time_enter'];

                if(($time_out >= $time_out_db) && ($time_enter <= $time_enter_db))
                {
                    echo "Time is in between";
                }
                else if (){
                    echo "Either one of the time_out or time_enter is in the range";
                }
            }
            mysqli_free_result($get);           
        }else{
            echo "Nothin here !";
        }
    }
?>
<form action="time.php" method="post">  
    <table> 
        <tr>
            <td><i class="fa fa-unlock-alt"></i> </td>
            <td>Time out : </td>
            <td><input type ="text" name="time_out" size="30"></td>
        </tr>
        <tr>
            <td><i class="fa fa-unlock-alt"></i> </td>
            <td>Time enter : </td>
            <td><input type ="text" name="time_enter" size="30"></td>
        </tr>
    </table>    

    <p><input class="btnSuccess" type ="submit" name="Submit" value="Submit"> </p>             
</form>

谢谢。

if以下情况，请在第二秒使用a or （ || ）条件：

<?php
    $connect      = mysqli_connect("", "root", "", "");
    global $connect;   

    if(isset($_POST['Submit'])){
        $time_out   = $_POST['time_out'];
        $time_enter = $_POST['time_enter'];

        $sql = "SELECT * FROM table";
        $get = mysqli_query($connect,$sql);
        if($get && mysqli_num_rows($get) > 0 ){              
            while($row = mysqli_fetch_assoc($get)){

            $time_out_db    = $row['time_out'];
            $time_enter_db  = $row['time_enter'];

                if(($time_out >= $time_out_db) && ($time_enter <= $time_enter_db))
                {
                    echo "Time is in between";
                }
                else if (($time_out >= $time_out_db) || ($time_enter <= $time_enter_db)){
                    echo "Either one of the time_out or time_enter is in the range";
                }
            }
            mysqli_free_result($get);           
        }else{
            echo "Nothin here !";
        }
    }
?>
<form action="time.php" method="post">  
    <table> 
        <tr>
            <td><i class="fa fa-unlock-alt"></i> </td>
            <td>Time out : </td>
            <td><input type ="text" name="time_out" size="30"></td>
        </tr>
        <tr>
            <td><i class="fa fa-unlock-alt"></i> </td>
            <td>Time enter : </td>
            <td><input type ="text" name="time_enter" size="30"></td>
        </tr>
    </table>    

    <p><input class="btnSuccess" type ="submit" name="Submit" value="Submit"> </p>             
</form>

请尝试以下代码。

if(($time_out_db>=$time_out) && ($time_enter<=$time_enter_db)){
    echo "Time is in between"
}elseif(($time_out_db>=$time_out) || ($time_enter<=$time_enter_db)){
    echo "Either one of the time_out or time_enter is in the range";
}
