PHP dynamic histogram implementation method, php dynamic histogram

The example in this article describes the PHP dynamic histogram implementation method. Share it with everyone for your reference. The specific analysis is as follows:

1. Demand

Query the total number of data items and the number of approved items in the last month, and make a histogram

2. Implementation code:

<!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);
