PHP代碼安排記錄按距離

-3

我想這工作了我的舊的數據庫結構PHP代碼安排記錄按距離

$lat = '-27.560263394765027'; 
$long = '153.08231055736542'; 
$query = "SELECT * , ((
    ACOS(SIN(".$lat." * PI() /180) * SIN(lat * PI() /180) + COS(".$lat." * PI() /180) * COS(lat * PI() /180) * COS((
    ".$long." - lon) * PI() /180)) *180/PI()) *60 * 1.1515) AS `distance` FROM `km_stores` HAVING `distance` <=100 ORDER BY distance LIMIT 0 , 10";

下述方法，我試圖採用同樣的原則和最大百公里半徑內找到最近的30家店這次我的數據庫結構完全不同，我需要運行一組sql查詢來獲得所需的輸出。我的查詢是

$select_resname = mysql_query("SELECT * FROM `wp_cf7dbplugin_submits` WHERE `form_name` = 'Add Store' AND `field_name` = 'store-name' LIMIT 0 , 30"); 
$select_resdesc = mysql_query("SELECT * FROM `wp_cf7dbplugin_submits` WHERE `form_name` = 'Add Store' AND `field_name` = 'store-description' LIMIT 0 , 30"); 
$select_reslat = mysql_query("SELECT * FROM `wp_cf7dbplugin_submits` WHERE `form_name` = 'Add Store' AND `field_name` = 'store-latitude' LIMIT 0 , 30"); 
$select_reslong = mysql_query("SELECT * FROM `wp_cf7dbplugin_submits` WHERE `form_name` = 'Add Store' AND `field_name` = 'store-longitude' LIMIT 0 , 30"); 
while(($fetch_resname = mysql_fetch_array($select_resname)) && ($fetch_resdesc = mysql_fetch_array($select_resdesc)) && ($fetch_reslat = mysql_fetch_array($select_reslat)) && ($fetch_reslong = mysql_fetch_array($select_reslong))){ 
    // Print the output 
}

在這種情況下，我該如何按照GEO位置安排記錄？

...什麼是您的數據庫結構？ – deceze

聽起來像你想使用['ORDER BY（）']（http://www.sql-tutorial.net/SQL-ORDER-BY.asp）和/或['GROUP BY（）']（http： //www.sql-tutorial.net/SQL-GROUP-BY.asp） –

@ Fred-ii- GROUP BY？我沒有看到。！？！ – Strawberry

$select_resname = mysql_query("SELECT * FROM `wp_cf7dbplugin_submits` WHERE `form_name` = 'Add Store' AND `field_name` = 'store-name' LIMIT 0 , 30");

$select_reslong = mysql_query("SELECT * FROM `wp_cf7dbplugin_submits` WHERE `form_name` = 'Add Store' AND `field_name` = 'store-longitude' LIMIT 0 , 30"); 

$resultAreas   = array();

    if($areaResult4!="") 
    { 
     $resultAreas[]= $areaResult4; 
    } 
} 
sort($resultAreas); 
print_r($resultAreas); // prints you the sorted result

我不認爲這會實時工作，因爲它按照數字順序排序，而不是按照距離排序。此外，獲得輸出就像「陣列」。 +1代碼。 – lock
