J'ai une base de données MySQL sur mon site Web et j'aimerais savoir comment obtenir une sortie XML via PHP des colonnes suivantes du tableau:
Un exemple avec 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();
Sortie:
<?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>";
}
}
?>
Cet extrait de code devrait vous donner un bon départ. Mais sans la structure XML souhaitée, il est difficile de faire mieux.
Cependant, je ne suis pas sûr que PHP soit la bonne solution pour cette tâche. De nombreux outils, comme phpmyadmin par exemple, peuvent générer des données mysql au format XML.
<?php
mysql_connect('myserver', 'username', 'password');
mysql_select_db('mydatabase');
$result = mysql_query('SELECT `udid`, `country` FROM `MyTable`');
$Result = "<?xml version='1.0' encoding='utf-8'?>\n<employees>\n";
while($data = mysql_fetch_assoc($Recordset1)) {
$Result .= " <employee>\n";
foreach($data as $key => $value) {
$Result .= " <$key>$value</$key>\n";
}
$Result .= " </employee>\n";
}
$Result .= "</employees>\n";
echo $Result;
?>
<?php
// Create connection
$con=mysqli_connect("localhost","root","root","students");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
//get student ID from URL
$STU_ID = $_GET['id'];
$sql = "SELECT * FROM students_info WHERE ID = ".$STU_ID;
$res = mysqli_query($con, $sql);
$xml = new XMLWriter();
$xml->openURI("php://output");
$xml->startDocument();
$xml->setIndent(true);
$xml->startElement('students');
while ($row = mysqli_fetch_assoc($res)) {
$xml->startElement("student");
$xml->writeElement("id", $row['ID']);
$xml->writeElement("name", $row['name']);
$xml->writeElement("gpa", $row['GPA']);
$xml->writeRaw($row['student']);
$xml->endElement();
}
$xml->endElement();
header('Content-type: text/xml');
$xml->flush();
// Free result set
mysqli_free_result($result);
// Close connections
mysqli_close($con);
?>
Output
<students>
<student>
<id>111</id>
<name>sara</name>
<gpa>4.5</gpa>
</student>
</students>
J'ai beaucoup de mal à trouver cette solution au format mysqli mais je n'ai trouvé nulle part la solution. Voici la solution que j'ai imaginée. J'espère que ça va aider quelqu'un.
<?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);
?>
