我不想使用緯度和經度顯示多個標記，只能通過存儲在mysql數據庫中的地址顯示。緯度和經度不是表格中的商店。如何使用google map api通過地址顯示多個位置標記？
我已經在它的工作，併成功地顯示一個標誌，但我的web應用程序要求我根據位置 這裏顯示多個標記的代碼：
<?php include_once("dbcon.php") ;
?>
<html>
<?php
$search = $_POST['search'];
$results = mysql_query("SELECT * FROM eventsTable WHERE eventLocation LIKE '%$search%'");
while ($row = mysql_fetch_assoc($results)) {
$ename = $row["eventName"];
$edate = $row["eventDate"];
$edetail=$row["eventDetails"];
$eloc = $row["eventLocation"];
$ecity = $row["eventCity"];
echo "<p> ".json_encode($eloc)."</p>"; echo json_encode($ecity); }
?>

請[停止使用'mysql_ *'函數]（http://stackoverflow.com/questions/12859942/why-shouldnt-i-use-mysql-functions-in-php）。他們不再被維護，並[正式棄用]（https://wiki.php.net/rfc/mysql_deprecation）。瞭解[準備的陳述]（http://en.wikipedia.org/wiki/Prepared_statement），並考慮使用PDO，[它不像你想象的那麼難]（http://jayblanchard.net/demystifying_php_pdo.html） 。 –
有多少「更多標記」？地理編碼器將工作約10而不會觸及查詢/速率限制。 – geocodezip
差不多40-50。 ：/ – ayleen
