Question

在我的Api中，我必须在地图中显示从数据库中获取经度和纬度的几个地方，我在php中工作，如何做到这一点？

Answer 1

Google tutorial很棒。但是因为它使用了已弃用的mysql_扩展，我将其修改为使用PDO。请参见地图HERE

<?php
require("phpsqlajax_dbinfo.php");

// Start XML file, create parent node
$dom = new DOMDocument("1.0");
$node = $dom->createElement("markers");
$parnode = $dom->appendChild($node);

// Opens a connection to a MySQL server
$dbh = new PDO("mysql:host=$host;dbname=$database", $username, $password);
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
try {
     $stmt = $dbh->query('SELECT * FROM markers WHERE 1');  
     // setting the fetch mode  
     $stmt->setFetchMode(PDO::FETCH_ASSOC);
     header("Content-type: text/xml");
    // Iterate through the rows, adding XML nodes for each
    while($row = $stmt->fetch()) {  
        // ADD TO XML DOCUMENT NODE
        $node = $dom->createElement("marker");
        $newnode = $parnode->appendChild($node);
        $newnode->setAttribute("name", $row['name']);
        $newnode->setAttribute("address", $row['address']);
        $newnode->setAttribute("lat", $row['lat']);
        $newnode->setAttribute("lng", $row['lng']);
        $newnode->setAttribute("type", $row['type']);
    }
echo $dom->saveXML();
}
catch(PDOException $e) {
    echo "Error .". $e->getMessage() ;// Remove or modify after testing 
    file_put_contents('PDOErrors.txt',date('[Y-m-d H:i:s]').", phpsqlajax_genxml.php , ". $e->getMessage()."\r\n", FILE_APPEND);  
 }
//Close the connection
$dbh = null; 
?>

您可以查看生成的HERE

<强> phpsqlajax_dbinfo.php

<?
$username="username";
$password="password";
$database="username-databaseName";
?>
