php实现按天数、星期、月份查询的搜索框

本文实例为大家分享了php实现按天数、星期、月份查询的搜索框，搜索时候展示数据的统计图，主要展示图形的效果，供大家参考，具体内容如下

1.ajax.php

<?php     $year = $_GET['y'];    if(!isset($_GET['m'])){       $month=1;    }else{         $month = $_GET['m'];    }    $week_arr = getMonthWeekArr($year, $month);    echo json_encode($week_arr);    die;                 /** * 获得系统某月的周数组，第一周不足的需要补足 *  * @param int $current_year * @param int $current_month * @return string[][] */function getMonthWeekArr($current_year, $current_month){     //该月第一天  $firstday = strtotime($current_year.'-'.$current_month.'-01');  //该月的第一周有几天  $firstweekday = (7 - date('N',$firstday) +1);  //计算该月第一个周一的时间  $starttime = $firstday-3600*24*(7-$firstweekday);  //该月的最后一天  $lastday = strtotime($current_year.'-'.$current_month.'-01'." +1 month -1 day");  //该月的最后一周有几天  $lastweekday = date('N',$lastday);  //该月的最后一个周末的时间  $endtime = $lastday-3600*24*($lastweekday%7);  $step = 3600*24*7;//步长值  $week_arr = array();  for ($i=$starttime; $i<$endtime; $i= $i+3600*24*7){    $week_arr[] = array('key'=>date('Y-m-d',$i).'|'.date('Y-m-d',$i+3600*24*6), 'val'=>date('Y-m-d',$i).'~'.date('Y-m-d',$i+3600*24*6));  }  return $week_arr;}

2.datehelper.php
