PHP XML fast read

Question

I load more than 50 XML files on my homepage. An example structure you can see here:

http://api.eve-central.com/api/marketstat?usesystem=30000142&hours=24&typeid=3683&minQ=10000

I need the price "sell" -> "min". So currently I run foreach() loops and stop when got it. But my page needs more than 30 seconds to handle this, I think I need a direct entry to the data like:

$min = $xml -> children() -> children() -> sell -> min;

Can anybody give me the right arithmetik?

Thx step

Is there any indication as to how often those figures are updated? If every minute then consider caching the finished page every minute and serving that up. — Cups

Those “files” are actually not files, but HTTP resources – and downloading 50 of them just takes a certain amount of time. As @Cups already said, see if you can cache those instead of reading them again every time. — C3roe

Use simplexml_load_file function. Its so simply and quick!

$xml = simplexml_load_file('http://api.eve-central.com/api/marketstat?usesystem=30000142&hours=24&typeid=3683&minQ=10000');

echo $xml->marketstat->type->sell->min; // 257.99

And SimpleXMLElement and file_get_contents

$xml_str = file_get_contents('http://api.eve-central.com/api/marketstat?usesystem=30000142&hours=24&typeid=3683&minQ=10000');
$xml = new SimpleXMLElement($xml_str);

echo $xml->marketstat->type->sell->min;  // 257.99

Interestingly enough, i am also working with the eve-central api at the moment. I have to give you a great tip though, eve-central allows you to pass requests for more than one item.

http://api.eve-central.com/api/marketstat?typeid=3683&typeid=3684&typeid=3685&typeid=3686&typeid=3687&typeid=3688&typeid=3689&usesystem=30000142&hours=24&minQ=10000

Like that.

Build a nice for loop that gets all the id's you want and let that construct an url like that. Once done adding all the &typeid=, add &usesystem=30000142&hours=24&minQ=10000 to it and do the simplexml_load_file(the name of your url here);

Now you can do a foreach on the xml output you get for all the items you wanted all at once.
