Php 将分组结果作为分离变量返回

我是mysql/php新手，正在尝试使用

$query = "SELECT expo_location,  SUM(total_sale) FROM _sales_db WHERE day IN('Friday') GROUP BY expo_location"; 

$result = mysql_query($query) or die(mysql_error());

// Print out result
while($row = mysql_fetch_array($result)){
  echo "<span style='font-weight:normal;color:#cfcfcf;'>"."Total ". $row['expo_location']. " = $". number_format((float)$row['SUM(total_sale)'], 2, '.', '')."</span>";
  echo "<br />";
}

我希望使用GROUPBY返回“expo_location”名称作为变量

Example
$Canton = 
$Malone = 
$Massena =

总而言之，将所有条目放在一列中，将它们分组并作为变量返回？

下面的代码将为您创建一个关联数组，以便您可以执行类似$expo_locations['Canton']的操作，其中包含295.94

    $query = "SELECT expo_location,  SUM(total_sale) FROM _sales_db WHERE day IN('Friday') GROUP BY expo_location"; 

    $result = mysql_query($query) or die(mysql_error());

    $expo_locations = array();

    // Print out result
    while($row = mysql_fetch_array($result)){
        $expo_locations[$row['expo_location']] = number_format((float)$row['SUM(total_sale)'], 2, '.', '');
    }

您可以在执行记录循环时将提取的位置数据存储在数组中，然后简单地将所有收集的数据内爆为字符串

$query = "SELECT expo_location,  SUM(total_sale) FROM _sales_db WHERE day IN('Friday') GROUP BY expo_location"; 

$result = mysql_query($query) or die(mysql_error());

$locations = array();

// Print out result
while($row = mysql_fetch_array($result)){
    $locations[] = $row['expo_location'];
}

$locations_string = implode(', ', $locations); // String version
var_dump($locations); // Displays array content.

$query = "SELECT expo_location,  SUM(total_sale) FROM _sales_db WHERE day IN('Friday') GROUP BY expo_location"; 

$result = mysql_query($query) or die(mysql_error());

$locations = array();

// Print out result
while($row = mysql_fetch_array($result)){
    $locations[] = $row['expo_location'];
}

$locations_string = implode(', ', $locations); // String version
var_dump($locations); // Displays array content.
