方法一：
//交易量折线图
public function actionDrawthirdcaiwusum()
{
if (Yii::$app->request->get("dayselect")) {
$day = Yii::$app->request->get("dayselect");
} else {
$day = 7;
}
$rows=Yii::$app->db->createCommand("select thirdid,FROM_UNIXTIME(yocreatetime,'%Y-%m-%d') as datetime
,SUM(yototal) as money
from ibd_third_oyihuo
LEFT JOIN ibd_shop ON (ibd_third_oyihuo.yosellerid=ibd_shop.suid or ibd_third_oyihuo.yobuyerid=ibd_shop.suid)
where (ystatus = 1 or ystatus = 4) and yotype<20
and yocreatetime>=unix_timestamp(DATE_FORMAT(subdate(now(),$day),'%Y-%m-%d'))
and yocreatetimequery();
$th=IbdThirdInfo::find()->all();
$id=[];
foreach($th as $val){
$id[]=$val->id;
}
for ($i = $day; 0 < $i; $i--) {
$result[] = date('Y-m-d', strtotime('-' . $i . ' day'));
foreach($id as $vvv){
${'money'.$vvv}[] =0;
}
}
foreach($rows as $k => $v){
foreach($result as $value =>$item){
// print_r($v);
$temp = reset($v);
$index = array_search($v['datetime'],$result);
${'money'.$temp}[$index]=sprintf("%.2f",$v['money']/100);
}
}
function my_json_decode($str) {
$str = preg_replace('/"(\w+)"(\s*:\s*)/is', '$1$2', $str); //去掉key的双引号
return $str;
}
$color = array("#EE0000","#00FFFF","#712704","#43A102","#049FF1","#FFA500","#4C4C4C","#00CCFF","#72CFD7","#FF8C05");
$res= array();
foreach($id as $vv){
$fileinfo['label'] = IbdThirdInfo::findOne(['id'=>$vv])->name;
$fileinfo['fill'] = true;
$fileinfo['borderColor'] = $color[$vv%10];
$fileinfo['pointBackgroundColor'] = "#fff";
$fileinfo['data'] = ${'money'.$vv};
array_push($res, $fileinfo);
}
$a = json_encode($result);
$c = my_json_decode(json_encode($res));
// print_r($c);die;
return $this->render('drawthirdcaiwusum',['a'=>$a,'c'=>$c,'day'=>$day]);
}
优化后的方法二
//交易量折线图
public function actionDrawthirdcaiwusum()
{
if (Yii::$app->request->get("dayselect")) {
$day = Yii::$app->request->get("dayselect");
} else {
$day = 7;
}
$rows=Yii::$app->db->createCommand("select thirdid,FROM_UNIXTIME(yocreatetime,'%Y-%m-%d') as datetime
,SUM(yototal) as money
from ibd_third_oyihuo
LEFT JOIN ibd_shop ON (ibd_third_oyihuo.yosellerid=suid)
where (ystatus = 1 or ystatus = 4) and yotype<20
and yocreatetime>=unix_timestamp(DATE_FORMAT(subdate(now(),$day),'%Y-%m-%d'))
and yocreatetimequery();
$th=IbdThirdInfo::find()->all();
$id=[];
foreach($th as $val){
$id[]=$val->id;
}
$rows = $rows->readAll();
for ($i = $day; 0 < $i; $i--) {//time
$result[] = date('Y-m-d', strtotime('-' . $i . ' day'));
}
foreach($id as $v1=>$thirdid){//第三方id
foreach($result as $value =>$item){ //日期
$isexit=0; //0表示不存在 1表示存在
foreach( $rows as $f =>$v){ //数据
if($item==$v['datetime']&&$thirdid==$v['thirdid']){
${'money'.$v['thirdid']}[]=sprintf("%.2f",$v['money']/100);
$isexit=1;
break;
}
}
if(!$isexit){
${'money'.$thirdid}[]=0;
}
}
}
function my_json_decode($str) {
$str = preg_replace('/"(\w+)"(\s*:\s*)/is', '$1$2', $str); //去掉key的双引号
return $str;
}
$color = array("#EE0000","#00FFFF","#712704","#43A102","#049FF1","#FFA500","#4C4C4C","#00CCFF","#72CFD7","#FF8C05");
$res= array();
foreach($id as $vv){
$fileinfo['label'] = IbdThirdInfo::findOne(['id'=>$vv])->name;
$fileinfo['fill'] = true;
$fileinfo['borderColor'] = $color[$vv%10];
$fileinfo['pointBackgroundColor'] = "#fff";
$fileinfo['data'] = ${'money'.$vv};
array_push($res, $fileinfo);
}
$a = json_encode($result);
$c = my_json_decode(json_encode($res));
// print_r($c);die;
return $this->render('drawthirdcaiwusum',['a'=>$a,'c'=>$c,'day'=>$day]);
}
再次优化
$th=IbdThirdInfo::find()->all();
$id=[];
foreach($th as $val){
$id[]=$val->id;
}
$rows = $rows->readAll();
for ($i = $day; 0 < $i; $i--) {//time
$result[] = date('Y-m-d', strtotime('-' . $i . ' day'));
$data[] = 0;
}
// foreach($id as $v1=>$thirdid){//第三方id
// foreach($result as $value =>$item){ //日期
// $isexit=0; //0表示不存在 1表示存在
// foreach( $rows as $f =>$v){ //数据
// if($item==$v['datetime']&&$thirdid==$v['thirdid']){
// ${'money'.$v['thirdid']}[]=sprintf("%.2f",$v['money']/100);
// $isexit=1;
// break;
// }
// }
// if(!$isexit){
// ${'money'.$thirdid}[]=0;
// }
// }
// }
foreach($th as $v1=>$thirdid){//第三方id
${'money'.$thirdid->id} = $data;
}
foreach( $rows as $f =>$v){ //数据
$index = array_search($v['datetime'],$result);
${'money'.$v['thirdid']}[$index]=sprintf("%.2f",$v['money']/100);
}
时间复杂度优化
//交易量折线图
public function actionDrawthirdcaiwusum()
{
if (Yii::$app->request->get("dayselect")) {
$day = Yii::$app->request->get("dayselect");
} else {
$day = 7;
}
$rows=Yii::$app->db->createCommand("select thirdid,FROM_UNIXTIME(yocreatetime,'%Y-%m-%d') as datetime
,SUM(yototal) as money
from ibd_third_oyihuo
LEFT JOIN ibd_shop ON (ibd_third_oyihuo.yosellerid=suid)
where (ystatus = 1 or ystatus = 4) and yotype<20
and yocreatetime>=unix_timestamp(DATE_FORMAT(subdate(now(),$day),'%Y-%m-%d'))
and yocreatetimequery();
$th=IbdThirdInfo::find()->all();
$id=[];
foreach($th as $val){
$id[]=$val->id;
}
$rows = $rows->readAll();
for ($i = $day; 0 < $i; $i--) {//time
$result[] = date('Y-m-d', strtotime('-' . $i . ' day'));
$data[] = 0;
}
// foreach($id as $v1=>$thirdid){//第三方id

}
function my_json_decode($str) {
$str = preg_replace('/"(\w+)"(\s*:\s*)/is', '$1$2', $str); //去掉key的双引号
return $str;
}
$color = array("#EE0000","#00FFFF","#712704","#43A102","#049FF1","#FFA500","#4C4C4C","#00CCFF","#72CFD7","#FF8C05");

// print_r($c);die;
return $this->render('drawthirdcaiwusum',['a'=>$a,'c'=>$c,'day'=>$day]);

//财务折线图
public function actionCaiwusum()
{
if (Yii::$app->request->get("dayselect")) {

} else {
$day = 7;
}
$rows=Yii::$app->db->createCommand("select FROM_UNIXTIME(yocreatetime,'%Y-%m-%d') as datetime

from ibd_oyihuo

主要要点：
1.php+mysql统计最近30天空值补0
1534411492(1).png
以EX1为例，2018/8/9号后数据为空，使用sql group by需要补0，网上有一种思路是leftjoin一张时间表数据默认为0。
查找最近的几天可以直接构建一个数组
for ($i = $day; 0 < $i; $i--) {//设定日期循环
$result[] = date('Y-m-d', strtotime('-' . $i . ' day'));//初始化时间，每次减1天
$money[] = 0;//初始化金额为0
$commission[] = 0;
}
然后，for循环取出从数据库拿到的数据，查找时间找出数组的位置，赋值给之前初始化为0的数组
foreach($rows as $k => $v){
foreach($result as $value =>$item){
$index = array_search($v['datetime'],$result);
$money[$index] = sprintf("%.2f",$v['money']/100);
$commission[$index] = sprintf("%.2f",$v['commission']/100);
}
}
这里写的有问题，首先$result是完整时间包含$rows从数据库找出的时间，应该调换过来，但会报错'DataReader cannot rewind. It is a forward-only reader.'要使用$rows = $rows->readAll();等填坑
$rows = $rows->readAll();
foreach($result as $value =>$item){
foreach($rows as $k => $v){
$index = array_search($v['datetime'],$result);
$money[$index] = sprintf("%.2f",$v['money']/100);
$commission[$index] = sprintf("%.2f",$v['commission']/100);
}
}
这样写也是没问题的。
后面传json给view就行了。
2.按第三方数量画折线
首先看chart.js的方法
datasets : [
{
label: "交易量(元)", //当前数据的说明
fill: true, //是否要显示数据部分阴影面积块 false:不显示
borderColor: "#36A2EB",//数据曲线颜色
pointBackgroundColor: "#fff", //数据点的颜色
data: , //填充的数据
},
{
label: "总后台佣金(元)", //当前数据的说明
fill: true, //是否要显示数据部分阴影面积块 false:不显示
borderColor: "#EE0000",//数据曲线颜色
pointBackgroundColor: "#fff", //数据点的颜色
data: , //填充的数据
}
]
思路：循环构建数组，转为json后，去掉key的双引号
其中变量名的递增可用用：${'money'.$vv}
function my_json_decode($str) {
$str = preg_replace('/"(\w+)"(\s*:\s*)/is', '$1$2', $str); //去掉key的双引号
return $str;
}
$color = array("#EE0000","#00FFFF","#712704","#43A102","#049FF1","#FFA500","#4C4C4C","#00CCFF","#72CFD7","#FF8C05");
$res= array();
foreach($id as $vv){
$fileinfo['label'] = IbdThirdInfo::findOne(['id'=>$vv])->name;
$fileinfo['fill'] = true;
$fileinfo['borderColor'] = $color[$vv%10];
$fileinfo['pointBackgroundColor'] = "#fff";
$fileinfo['data'] = ${'money'.$vv};
array_push($res, $fileinfo);
}
$a = json_encode($result);
$c = my_json_decode(json_encode($res));
html里直接输出
