<?php	
//计算上一个月的今天

    $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';

//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);
