搜索数据库中有两个查询mysql / php的行

Question

我有一个带有旅程的数据库，我试图在表中找到通过两个查询的所有结果（比如INTERSECT），但我只能得到它给我两组结果。查询搜索两端半径范围内的所有记录sql是旅程的开始，sql2是旅程的结束

<?php

include_once 'dbconnect.php';


     // Get lat and long by address 
     $dlocation = 'SW1A 0AA';        
        $address = $dlocation; // Google HQ
        $prepAddr = str_replace(' ','+',$address);
        $geocode=file_get_contents('https://maps.google.com/maps/api/geocode/json?address='.$prepAddr.'&sensor=false');
        $output= json_decode($geocode);
        $lat = $output->results[0]->geometry->location->lat;
        $lng = $output->results[0]->geometry->location->lng;

        $lng2 = $output->results[0]->geometry->location->lng;

$sql = "SELECT adpastrip_id, ( 3959 * acos( cos( radians($lat) ) * cos( radians( lat1 ) ) * cos( radians( long1 ) - radians($lng) ) + sin( radians($lat) ) * sin( radians( lat1 ) ) ) ) AS distance FROM addgoodstrip HAVING distance < 10 ORDER BY distance LIMIT 0 , 20";

    }
}
