如何設置動態通過位置

我有很多地方通過。之前，我只是靜靜地設置這些位置。現在，我創建了一個公司表格，並創建了一個用於添加，刪除和更新公司詳細信息的界面。因此，自創建通行證以來，我應該創建公司的這些位置。因此，我應該如何動態設置它們？我用這樣的代碼靜態地點：

取出記錄，產生一個數組，並將其編碼成json字符串。 – Rikesh 2013-05-09 04:47:11

如何使用數組通過從公司表中進行選擇來設置它們？ – malinchhan 2013-05-09 04:47:26

「locations」：[ {「longitude」：「'。$ long。'」，「latitude」：「'。$ lat。'」，「relevantText」：「'。$ name。' '。$ discount。'「 }} – malinchhan 2013-05-09 04:57:47

我只是試試這個，我可以看到像我寫的靜態結果：

$query5 = mysql_query("select * from company"); 

while ($row5 = mysql_fetch_array($query5)){ 
    $companyName = $row5['relevantTextName']; 
    $discount = $row5['relevantTextDiscount']; 
    $long = $row5['longitute']; 
    $lat = $row5['latitute']; 
    $link = $row5['link']; 

    $location['locations'][] = array("longitute" => $long, "latitute" => $lat, "relevantText" => $companyName." (" . $discount. "%)"); 
} 
$jsonString = json_encode($location) ; 

error_log("Locations: ".$jsonString,0);

做

$qry = mysql_query($conn, "select longitude, latitude, relevantText from location_table"); 
$ret = array(); 
while($rec = mysql_fetch_assoc($qry)){ 
    $ret[] = $rec; 
} 
// return or print or do something with the data here. 
return json_encode(array("locations"=>$ret));

json_encode將返回numericaly索引PHP數組作爲JSON數組和字符串與數組的索引作爲JavaScript對象......希望這有助於

謝謝，我會測試它！ – malinchhan 2013-05-09 05:10:01

另外請記住，通行證只能有10個地點。其餘的將被忽略，所以你應該在查詢中加入LIMIT 10，並且應該添加一個WHERE或ORDER BY的條件來提供一些邏輯來選擇10。 – PassKit 2013-05-09 05:12:26

看着你試圖複製最後一行的JSON實際上應該讀取返回json_encode（array（「locations」=> $ ret））; – Orangepill 2013-05-09 05:13:02

嘗試這樣的..

<?php 
$locations = array(); 
$result = $mysqli->query("select longitude, latitude, relevantText FROM company"); 

$inc=0; 
while ($row = $result->fetch_array()){ 
     $locations['locations'][$inc]['longitude'] = $row['longitude']; 
     $locations['locations'][$inc]['latitude'] = $row['latitude']; 
     $locations['locations'][$inc]['relevantText'] = $row['relevantText']; 

    $inc++; 
    } 

echo json_encode($locations); 

?>
