Holen Sie sich MySQL-Datenbank-Ausgabe über PHP in XML

Ich habe eine MySQL-Datenbank auf meiner Website und möchte wissen, wie ich eine XML-Ausgabe über PHP der folgenden Spalten in der Tabelle erhalten kann:

  1. du tatest
  2. land
11
max_

Ein Beispiel mit XMLWriter .

mysql_connect('server', 'user', 'pass');
mysql_select_db('database');

$sql = "SELECT udid, country FROM table ORDER BY udid";
$res = mysql_query($sql);

$xml = new XMLWriter();

$xml->openURI("php://output");
$xml->startDocument();
$xml->setIndent(true);

$xml->startElement('countries');

while ($row = mysql_fetch_assoc($res)) {
  $xml->startElement("country");

  $xml->writeAttribute('udid', $row['udid']);
  $xml->writeRaw($row['country']);

  $xml->endElement();
}

$xml->endElement();

header('Content-type: text/xml');
$xml->flush();

Ausgabe:

<?xml version="1.0"?>
<countries>
 <country udid="1">Country 1</country>
 <country udid="2">Country 2</country>
 ...
 <country udid="n">Country n</country>
</countries>

<?php

mysql_connect('myserver', 'username', 'password');
mysql_select_db('mydatabase');
$result = mysql_query('SELECT `udid`, `country` FROM `MyTable`');

while($data = mysql_fetch_assoc($result)) {
  foreach($data as $key => $value) {
    echo "<$key>$value</$key>";
  }
}

?>

Dieses Code-Snippet sollte Ihnen einen guten Start ermöglichen. Aber ohne die gewünschte XML-Struktur ist es schwer, es besser zu machen.

Ich bin mir jedoch nicht sicher, ob PHP die richtige Lösung für diese Aufgabe ist. Viele Tools, wie zum Beispiel phpmyadmin, können MySQL-Daten im XML-Format ausgeben.

Ich habe viel Mühe, diese Lösung im MySQL-Format herauszufinden, aber nirgendwo habe ich die Lösung gefunden. Unten ist die Lösung, die ich dachte. Hoffe, es wird jemandem helfen.

<?php
//Create file name to save
$filename = "export_xml_".date("Y-m-d_H-i",time()).".xml";

$mysql = new Mysqli('server', 'user', 'pass', 'database');
if ($mysql->connect_errno) {
    throw new Exception(sprintf("Mysqli: (%d): %s", $mysql->connect_errno, $mysql->connect_error));
}

//Extract data to export to XML
$sqlQuery = 'SELECT * FROM t1';
if (!$result = $mysql->query($sqlQuery)) {
    throw new Exception(sprintf('Mysqli: (%d): %s', $mysql->errno, $mysql->error));
}

//Create new document 
$dom = new DOMDocument;
$dom->preserveWhiteSpace = FALSE;

//add table in document 
$table = $dom->appendChild($dom->createElement('table'));

//add row in document 
foreach($result as $row) {
    $data = $dom->createElement('row');
    $table->appendChild($data);

    //add column in document 
    foreach($row as $name => $value) {

        $col = $dom->createElement('column', $value);
        $data->appendChild($col);
        $colattribute = $dom->createAttribute('name');
        // Value for the created attribute
        $colattribute->value = $name;
        $col->appendChild($colattribute);           
    }
}

/*
** insert more nodes
*/

$dom->formatOutput = true; // set the formatOutput attribute of domDocument to true 
// save XML as string or file 
$test1 = $dom->saveXML(); // put string in test1
$dom->save($filename); // save as file
$dom->save('xml/'.$filename);   
?>
