Question

我正在使用mysql_query从mysql中获取记录，但它没有返回确切的记录，而我在phpmyadmin中运行相同的查询时返回正确的记录。

$sql    = "SELECT * , (3959 * acos(cos(radians(28.5355161)) * cos(radians(latitude)) * cos( radians(longitude) - radians(77.39102649999995)) + sin(radians(28.5355161)) * sin(radians(latitude)))) AS distance FROM businesses   HAVING distance < 100 ORDER BY distance DESC LIMIT 0,10";
$result = mysql_query($sql, $link);

while ($row = mysql_fetch_assoc($result)) {
$arr[]=$row;
}
echo '<pre>';print_r($arr);

仅返回单个记录：

    Array
(
    [0] => Array
        (
            [id] => 8
            [name] => sayeed
            [address] => Test
            [contact_number] => 865335312
            [avatar] => 4f38030400f4e62bbc3cb9aa4e23ac45.jpg
            [route_short] => 
            [route_long] => 
            [postal_code_short] => 
            [postal_code_long] => 
            [neighborhood_short] => 
            [neighborhood_long] => 
            [street_number_short] => 
            [street_number_long] => 
            [country_short] => IN
            [country_long] => India
            [locality_short] => Noida
            [locality_long] => Noida
            [administrative_area_level_1_short] => UP
            [administrative_area_level_1_long] => Uttar Pradesh
            [administrative_area_level_2_short] => Gautam Bud
            [administrative_area_level_2_long] => Gautam Buddh Nagar
            [formatted_address] => Noida, Uttar Pradesh, India
            [latitude] => 28.5355161
            [longitude] => 77.39102649999995
            [time_created] => 0000-00-00 00:00:00
            [description] => Test
            [contact_email] => mohd.sayeed@udaantechnologies.com
            [website] => www.udaantechnologies.com
            [category] => 1
            [distance] => 0.00005899369716644287
        )

)

如果我使用phpmyadmin运行相同的查询，则返回4条记录。

您的查询在乘法过程中有enter code here！这应该会导致错误。尝试删除它。

SELECT * , (3959 * acos(cos(radians(28.5355161)) * `enter code here`cos(radians...

请改为尝试：

$sql = "
    SELECT *,
           (3959 *
             acos(
               cos(radians(28.5355161)) *
               cos(radians(latitude)) *
               cos(radians(longitude) - radians(77.39102649999995)) +
               sin(radians(28.5355161)) *
               sin(radians(latitude))
             )
           ) AS distance
      FROM businesses
    HAVING distance < 100
  ORDER BY distance DESC LIMIT 0,10";
$result = mysql_query($sql, $link);
while ($row = mysql_fetch_assoc($result)) {
    $arr[] = $row;
}
echo '<pre>';
print_r($arr);
echo '</pre>';

使用sin，cos或radians时，mysql_query没有得到所有记录
