回答1:

Although I think XMLWriter is best suited for that task (like in my other answer), if you really want to do it with SimpleXML, here's how:

$fp = fopen('data.txt', 'r');

$xml = new SimpleXMLElement('<allproperty></allproperty>');

while ($line = fgetcsv($fp)) {
   if (count($line) < 4) continue; // skip lines that aren't full

   $node = $xml->addChild('aproperty');
   $node->addChild('postcode', $line[0]);
   $node->addChild('price', $line[1]);
   $node->addChild('imagefilename', $line[2]);
   $node->addChild('visits', $line[3]);
}

echo $xml->saveXML();

You will notice that the output is not as clean: it's because SimpleXML doesn't allow you to automatically indent tags.

I will suggest you to use XMLWriter instead, because it is best suited for that (and it's also built-in like SimpleXML):

$fp = fopen('data.txt', 'r');

$xml = new XMLWriter;
$xml->openURI('php://output');
$xml->setIndent(true); // makes output cleaner

$xml->startElement('allproperty');
while ($line = fgetcsv($fp)) {
   if (count($line) < 4) continue; // skip lines that aren't full

   $xml->startElement('aproperty');
   $xml->writeElement('postcode', $line[0]);
   $xml->writeElement('price', $line[1]);
   $xml->writeElement('imagefilename', $line[2]);
   $xml->writeElement('visits', $line[3]);
   $xml->endElement();
}
$xml->endElement();

Of course, you can change the php://output argument to a filename if you want it to output to a file.
