Converting XML to CSV using PHP - php

Question

I need to convert an XML file to CSV.
I have a script but I am unsure of how to use it to my needs.
Here is the script
$filexml='141.xml';
if (file_exists($filexml)) {
$xml = simplexml_load_file($filexml);
$f = fopen('141.csv', 'w');
foreach ($xml->item as $item) {
fputcsv($f, get_object_vars($item),',','"');
}
fclose($f);
}
The file is called 141.xml and here is some of the code in the XML which I need to convert.
<?xml version="1.0" encoding="UTF-8" ?>
<rss xmlns:g="http://base.google.com/ns/1.0" version="2.0">
<channel>
<item>
<title><![CDATA[//title name]]></title>
<link><![CDATA[https://www.someurl.co.uk]]></link>
<description><![CDATA[<p><span>Demo Description</span></p>]]></description>
<g:id><![CDATA[4796]]></g:id>
<g:condition><![CDATA[new]]></g:condition>
<g:price><![CDATA[0.89 GBP]]></g:price>
<g:availability><![CDATA[in stock]]></g:availability>
<g:image_link><![CDATA[https://image-location.png]]></g:image_link>
<g:service><![CDATA[Free Shipping]]></g:service>
<g:price><![CDATA[0 GBP]]></g:price>
</item>
I am running the script from SSH using:
php /var/www/vhosts/mywebsite.co.uk/httpdocs/xml/convert.php
If you can help me, it would be really appreciated :)
Thanks

Consider passing XML data into an array $values and exporting array by row to csv.
Specifically, using the xpath() function for the XML extraction, iterate through each <item> and extract all its children's values (/*). By the way, I add headers in the CSV file.
$filexml='141.xml';
if (file_exists($filexml)) {
$xml = simplexml_load_file($filexml);
$i = 1; // Position counter
$values = []; // PHP array
// Writing column headers
$columns = array('title', 'link', 'description', 'id', 'condition',
'price', 'availability', 'image_link', 'service', 'price');
$fs = fopen('141.csv', 'w');
fputcsv($fs, $columns);
fclose($fs);
// Iterate through each <item> node
$node = $xml->xpath('//item');
foreach ($node as $n) {
// Iterate through each child of <item> node
$child = $xml->xpath('//item['.$i.']/*');
foreach ($child as $value) {
$values[] = $value;
}
// Write to CSV files (appending to column headers)
$fs = fopen('141.csv', 'a');
fputcsv($fs, $values);
fclose($fs);
$values = []; // Clean out array for next <item> (i.e., row)
$i++; // Move to next <item> (i.e., node position)
}
}

Try out below code. And the XML file is having syntax error, the closing tag for rss and channel is missing.
$filexml='141.xml';
if (file_exists($filexml))
{
$xml = simplexml_load_file($filexml);
$f = fopen('141.csv', 'w');
createCsv($xml, $f);
fclose($f);
}
function createCsv($xml,$f)
{
foreach ($xml->children() as $item)
{
$hasChild = (count($item->children()) > 0)?true:false;
if( ! $hasChild)
{
$put_arr = array($item->getName(),$item);
fputcsv($f, $put_arr ,',','"');
}
else
{
createCsv($item, $f);
}
}
}
