如何加入在时间字段中提交的日期php

Question

我需要加入日期字段bid_staring_date，时间字段为bid_staring_time，并检查当前日期时间$current_date_time=date('M d,Y H:i:s');我该怎么做？

<?php 
    $current_date_time=date('M d,Y H:i:s'); 
    $bid_schedule_date=date('M d,Y',strtotime($row['bid_staring_date'])); 
    $bid_schedule_time=date('H:i:s',strtotime($row['bid_staring_time'])); 
    echo $bid_schedule_date_time=date('M d,Y H:i:s',(strtotime($bid_schedule_date)+strtotime($bid_schedule_time))); 
    $bid_schedule_id=$row['bid_schedule_id']; 

    if($current_date_time>=$bid_schedule_date_time){ 
     $btn_type="btn btn-success"; 
     $btn_value="Bid Now"; 
     $btn_link="openbid.php?pid=$bid_schedule_id";                  
    } 
    else 
    { 
     $btn_type="btn btn-danger"; 
     $btn_value="Bid Not Started"; 
     $btn_link="#";                  
    } 
    echo "<a href='$btn_link' class='$btn_type'>$btn_value</a>"; 
?> 

Answer 1

I need to also get top largest 5 bid_rate for each bid_shedule_id

SELECT * FROM tbl_bid_history ORDER BY bid_rate DESC limit 3
this query returns only top 5 values of same bid_shedule_id

Answer 2

$game_date = game['date']; 
    $game_time = game['time']; 

    $combined_date_and_time = $game_date . ' ' . $game_time; 
    $past_date = strtotime($combined_date_and_time);
