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>
<?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);
//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);
?>
