本文实例讲述了PHP动态柱状图实现方法。分享给大家供大家参考。具体分析如下：

1.需求

查询最近一个月的数据总条数和审核通过的条数，做成柱状图

2.实现代码：

<!DOCTYPE html> 
<&#63;php   
//计算上一个月的今天 
function last_month_today($time){ 
  $last_month_time = mktime(date("G", $time), date("i", $time),date("s", $time), date("n", $time), 0, date("Y",$time)); 
  $last_month_t = date("t", $last_month_time); 
  if ($last_month_t < date("j", $time)) { 
    return date("Y-m-t H:i:s", $last_month_time); 
  } 
  return date(date("Y-m", $last_month_time) . "-d", $time); 
} 
&#63;> 
 
<&#63;php 
  include dirname(dirname(dirname(__FILE__))).'/config.php'; 
  $endDate = date('Y-m-d');   
  $date = strtotime($endDate); 
  $beginDate= last_month_today($date); 
 
//查询最近一个月的总的数据条数 
$sql = 'select count(*) from newpro where p_date>\''.$beginDate.'\' and p_date<\''.$endDate.'\''; 
//$sql = "select count(*) from newpro where p_date>'$beginDate' and p_date <'$endDate'";//这条语句也可以 
$d = db()->query($sql)->fetch(PDO::FETCH_NUM); 
//echo "总的数据条数：".$d[0]; 
 
//查询审核通过的数据条数 
$sql2=$sql.' and is_pa_check_first=1 and is_pa_check_second=1 and is_pa_check_third=1'; 
$d2 = db()->query($sql2)->fetch(PDO::FETCH_NUM); 
//echo "审核通过的数据条数：".$d2[0]; 
 
//查询一次审核通过的条数 
$sql3=$sql.' and is_pa_check_first=1'; 
$d3 = db()->query($sql3)->fetch(PDO::FETCH_NUM); 
 
//查询二次审核通过的条数 
$sql4=$sql.' and is_pa_check_first=1 and is_pa_check_second=1'; 
$d4 = db()->query($sql4)->fetch(PDO::FETCH_NUM);
