I am trying to make a xml file from the data stored in my local db using php. But i am having a problem with it. as when I hard code the value I am able to get the xml file but when i am trying to call from the database i am not able to do it? so can some one help me out with it.

so here is the code that i wrote..

<?php

 include 'config.php';
 include 'database.php';

$sql = "select title, content, url from table limit 100";
$results = Database::GetAll($sql);

$xml = new DomDocument("1.0","UTF-8");

$content = $xml->createElement("content");
$content = $xml->appendChild($content);

foreach($results as $result) {
    $item = $xml->createElement("item");
    $item = $content->appendChild($item);

    $title = $xml->createElement("title",$result['title']);
    $title = $item->appendChild($title);

    $description = $xml->createElement("description",$result['content']);
    $description = $item->appendChild($description);

    $link = $xml->createElement("link",htmlspecialchars($result['url']));
    $link = $item->appendChild($link);
}

$xml->FormatOutput = true;
$output = $xml->saveXML();
$xml->save("xmls.xml");


?>

here Database::GetAll($sql) is a class that i have created, it executes the query and gets the table contents. the config file consists of all the database credentials and database.php is the file with the class of database.

The XML that i would want is

<content>
<item>
<title>....</title>
<description>....</description>
<url>....</url>
</item>

<item>
<title>....</title>
<description>....</description>
<url>....</url>
</item>

<item>
<title>....</title>
<description>....</description>
<url>....</url>
</item>

...till 100 values..
</content>

here the .... between the tags represent the datas retrieved from the database using mysql. var_dump($results) gives me all the three required values upto the 100th row.

and these are the errors that I am getting while using my code..

Answer 1

Thank you all for helping me out, with all your help and a little help from google i found the answe for it..

the updated code is as follow..

$xml = new DomDocument("1.0","UTF-8");

$content = $xml->createElement("content");
$content = $xml->appendChild($content);

foreach($results as $result) {
    $item = $xml->createElement("item");

    $title = $xml->createElement("title",htmlspecialchars($result['title']));
    $title = $item->appendChild($title);

    $description = $xml->createElement("description",htmlspecialchars($result['content']));
    $description = $item->appendChild($description);

    $link = $xml->createElement("link",htmlspecialchars($result['url']));
    $link = $item->appendChild($link);

    $item = $content->appendChild($item);

}

$xml->FormatOutput = true;
$output = $xml->saveXML();
$xml->save("xmls.xml");

I have only included the xml file. you can just create a connection with your db and use this code.
