php如何判断单双大小？

Question

php如何判断单双大小？比如采集调用号码为4,5,6,7,8 总和为 30 小于或等于22为小，大于为大， 由于三位4，6，8为双，二位5，7为单，所以为双，反之为单，如果为小就调用0，为大就调用1，单调用为0，双就调用为1！列如为大调用sumBigSmal“:1;”为双sumSingleDouble":1,"

<?php
//$js = file_get_contents('http://kai.kai800.net/getbaseruishi10mshicai?lotCode=10060');
//echo($js);
$servername = "localhost";
$username = "qxc";
$password = "123456";
$dbname = "qxc";

// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("连接失败: " . $conn->connect_error);
}

$sql = "SELECT * FROM qxc.jz_data where type='7' order by number desc LIMIT 1";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
// 输出数据
while($row = $result->fetch_assoc()) {
$number=$row["number"];
$data=$row["data"];
$arr=$row["data"];
$num1=$arr[0]+$arr[1]+$arr[2]+$arr[3]+$arr[4]+$arr[5]+$arr[6]+$arr[7]+$arr[8];

$time=date('Y-m-d H:i:s',$row["time"]);
$drawTime=date('Y-m-d H:i:s',$row["time"]+180);
$serverTime=date('Y-m-d H:i:s');
$drawCount=substr($number,strlen($number)- 3,3);
}
} else {

}

$conn->close();

        $arr = [4,5,6,7,8];
        //判断数字奇偶性
        $single = $double = [];
        foreach ($arr as $val){
            if($val%2 == 0){//双
                $double[] = $val;
            }else{//单
                $single[] = $val;
            }
        }
        $count_single = count($single);
        $count_double = count($double);
        if($count_single > $count_double){//单数大于双数，调用0
            return 0;
        }elseif ($count_single < $count_double){
            return 1;
        }

        $sum = array_sum($arr);
        if($sum <= 22){ //小
            return 0;//调用0
        }else{
            return 1;
        }

写了个demo，你自己看着改，应该能满足你的需求
