PHP实现动态柱状图改进版

本文实例分析了PHP实现动态柱状图的改进版。分享给大家供大家参考。具体分析如下：

前面已经写过如果只做动态柱状图的情况，其实原理还是很简单的。因为昨天下午有新的需求，今天上午又修改了一番，并将数据根据编号不同分割显示在表中。

下面把代码粘出来，方便以后自己查看，思路只是一时的火花，今天我想出来这么做，不一定下次还能想得到，也不用费劲的去想，所以写成笔记是比较好的形式。

<!DOCTYPE html>

<?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);

}

?>

<?php

include dirname(dirname(dirname(__FILE__))) . '/config.php';

$endDate = date('Y-m-d');

$date = strtotime($endDate);

$beginDate = last_month_today($date);

$sql = 'select count(*) from newpro where p_date>\'' . $beginDate . '\' and p_date<\'' . $endDate . '\'';

$d = db()->query($sql)->fetch(PDO::FETCH_NUM);

$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);

$sql3 = $sql . ' and is_pa_check_first=1';

$d3 = db()->query($sql3)->fetch(PDO::FETCH_NUM);

$sql4 = $sql . ' and is_pa_check_first=1 and is_pa_check_second=1';

$d4 = db()->query($sql4)->fetch(PDO::FETCH_NUM);

// 查询每个人通过审核的情况：

$sqlab = 'select d_m,sum(sroce) as total_score,count(d_m) as total_number

from newpro

  where is_pa_check_first=1

  and is_pa_check_second=1

  and is_pa_check_third =1

group by d_m';

$row = db()->query($sqlab)->fetchAll(PDO::FETCH_ASSOC);

数据库方便就不弄了，其实，根据查询的表名和字段名，是很容易建一个测试的数据表的。关键是思路，无论怎么变，思路是关键。
