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> 
<&#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); 
$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);

</html>

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。

为了更加方便的了解代码的效果，截个图吧

希望本文所述对大家的php程序设计有所帮助。

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

PHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
