Help with PHP web page

I have a webpage that has a roster for World of Warcraft on it. I would like to know how do I create summary statistics for number of each Class, number of each Race, and number of each Gende开发者_如何学Gor. Can someone please help. The data is read in from an XML page into an array. Thank you.

I think you can create count array for each of your criteria and loop all your input data. Here is how it can look:

$races_count = array();
foreach ($persons as $person) {
    $races_count[ $person['race'] ] ++;
}

print_r($races_count);

You can start by using the xml functionality built into php:

Then use foreach loops to summarize the data.
