通过PHP将SQLite转换为XML

Question

我确信这可以完成。 我需要从SQLite数据库中提取数据&将其快速转换为XML，因此可以通过融合图来读取它以显示漂亮的图。

我已经看到它与MySQL完成，但我发现很难找到关于SQlite到XML的信息。

<?php 

header("Content-type: text/xml"); 

$host = "localhost"; 
$user = "root"; 
$pass = ""; 
$database = "test"; 

$linkID = mysql_connect($host, $user, $pass) or die("Could not connect to host."); 
mysql_select_db($database, $linkID) or die("Could not find database."); 

$query = "SELECT * FROM blog ORDER BY date DESC"; 
$resultID = mysql_query($query, $linkID) or die("Data not found."); 

$xml_output = "<?xml version=\"1.0\"?>\n"; 
$xml_output .= "<entries>\n"; 

for($x = 0 ; $x < mysql_num_rows($resultID) ; $x++){ 
    $row = mysql_fetch_assoc($resultID); 
    $xml_output .= "\t<entry>\n"; 
    $xml_output .= "\t\t<date>" . $row['date'] . "</date>\n"; 
     // Escaping illegal characters 
     $row['text'] = str_replace("&", "&", $row['text']); 
     $row['text'] = str_replace("<", "<", $row['text']); 
     $row['text'] = str_replace(">", "&gt;", $row['text']); 
     $row['text'] = str_replace("\"", "&quot;", $row['text']); 
    $xml_output .= "\t\t<text>" . $row['text'] . "</text>\n"; 
    $xml_output .= "\t</entry>\n"; 
} 

$xml_output .= "</entries>"; 

echo $xml_output;

这里是你发布的代码的一个版本，但使用SQLite替代的MySQL：

<?php 

header("Content-type: text/xml"); 

$dbhandle = sqlite_open('sqlitedb'); 
$query = sqlite_query($dbhandle, 'SELECT * FROM blog ORDER BY date DESC'); 
$result = sqlite_fetch_all($query, SQLITE_ASSOC); 

try { 
    $db = new PDO("sqlite:/path/to/database.db"); 
} catch(PDOException $e) { 
    die('Unable to connect to database: ' . $e->getMessage()); 
} 
$query = $db->prepare("SELECT * FROM blog ORDER BY date DESC"); 
$query->execute(); 
$result = $query->fetchAll(); 

$xml_output = "<?xml version=\"1.0\"?>\n"; 
$xml_output .= "<entries>\n"; 
foreach ($result as $row) { 
    $xml_output .= "\t<entry>\n"; 
    $xml_output .= "\t\t<date>" . $row['date'] . "</date>\n"; 
    // Escaping illegal characters 
    $row['text'] = str_replace("&", "&", $row['text']); 
    $row['text'] = str_replace("<", "<", $row['text']); 
    $row['text'] = str_replace(">", "&gt;", $row['text']); 
    $row['text'] = str_replace("\"", "&quot;", $row['text']); 
    $xml_output .= "\t\t<text>" . $row['text'] . "</text>\n"; 
    $xml_output .= "\t</entry>\n"; 
} 

$xml_output .= "</entries>"; 
$db = null; 

这里是PHP documentation for PDO以获取更多信息。

这是一个tutorial for using PDO。

编辑：更改代码以使用PDO而不是sqlite_*函数。
