BetterPHP

OK so I want to do something like this in my PHP code, except I don't think its supported... How would I be able to do this?

$xml = simplexml_load_file("odds.xml");
$players = $xml->pool.$number->players

Not really sure what that sample is meant to be doing Could you post some sample data and expected result ?

Ok I don't really want to disclose any real code but I'll give an example...
Here is a xml file

<?xml ?>
<pools>
<pool1>
<swimmers>10</swimmers>
</pool1>
<pool2>
<swimmers>15</swimmers>
</pool2>
</pools>

And so I can parse it as so

$xml = simplexml_load_file("pools.xml");
$players = $xml->pool1->swimmers;
echo $players;

but I want to place it in a function as so

<?php
function get_swimmers($pool){
$xml = simplexml_load_file("pools.xml");
$players = $xml->pool.$pool->swimmers;
echo $players;
}
?>

but that doesn't really work...

Ah you need to need to know the element name dynamically.

I believe you can do that like this

$players = $xml->{"pool{$pool}"}->swimmers;
